Used this video to help rebuild the exact same jack. The jack originally was my grandfather's(WW2 vet), then my dad's and now mine. I rebuilt to give to my son. 4 generations of my family will have used the jack and it holds so many memories. I used it to change oil in my first car at 16, I am 61 now. When i touch the handle memories instantly flood back of family members long gone. Thanks for excellent video.
Thank you very much Carlton for your kind words. You made my day. I’m glad you found it helpful. How great that that is now gone for generations. It’ll certainly go many generations to come. The rebuild for me was a lot of fun and I’m really glad that it was helpful for you. Consider subscribing. Thank you. Joe.
this was a well done video Doc. hopefully more people my age will come across your channel and be inspired to fix and repair instead of trashing and buying new.
Thank you very much for your comment. Right now I have 5400 subscribers that I’m proud about and I’m working to grow my channel. It’s really a pleasure and particularly nice to receive comments like yours. Thanks again. Take care, Joe.
Nice. Thank you for the how too video. Much appreciated. I bought mine in 1986. I didn't have much money back then, but I certainly got my money's worth out of this jack. I thought about buying a new jack. Glad I didn't, got the seal kit instead. Now my trusty jack can be passed down to my grandson. Thanks again!
Hello Mary Mac, Thanks for your nice comments. Yes enjoy getting that baby going again and lasting for many more generations. Consider subscribing. Thanks, Joe.
Thanks for this video! I got one of these 1.5 Ton jacks when Sears began carrying, I believe it was 1978. My neighbor just gave be another identical as he is moving and installing a lift. These are made in Japan and overcame some of the deficiencies of the Hein-Warner WG model I also have. It is interesting how the adjustable pressure relief in the end of the rod allowed the company to sell the same frame for 1.5, 2.0 and 3.0 jack. My 12002 sold for $99 and the H-W of that time was $500+. Lesson learned. Presumably with higher quality U-seal on the rod. Economical thinking on their part with high part commonality for manufacturing. My H-W has been rebuilt once and repaired many times. My original Sears 328-12002 model just started dropping the load and the gift 12002 weeps externally. Parts ordered for both. Next is restoration of a 1967 VW engine lift from the VW dealer!! The pump has leaked forever. It looks like a modified transmission jack. Too much for funnel, switching to syringe . . . . .
Thank you for your very nice comment. You have a lot of experience with those products and I know how much fun it is to have a successful rebuild. Carry on. Consider subscribing. Thanks. Joe.
Thanks for the video! I’ve subscribed. I’ll be rebuilding that EXACT model this weekend, so your tutorial was invaluable. I bought mine new in 1982 when my oldest son was one! I now have three kids and five grandchildren!
I'm 40 years old and rebuilt my dad's first Sears 1ton floor jack. I wish I watched this video first. Lot of things I didn't do with the kit. But it's working like a champ
In 1980 my dad purchased a Sears 3 ton floor jack and after lifting n lowering several vehicles including a semi truck transmission the jack still works. Amazing craftsmanship. Probably nothing out there made in the USA still to compare
Those Jack’s were made in Japan and very well-made. Yes, they have some seals that will fail but overall their quality and durability obviously is excellent. I’m glad you’re still works great it may need to rebuild someday consider subscribing. Thanks Joe.
Excellent video, sir. I inherited this jack from my father-in-law who was a mechanic. Loved using it. I got 2 of the ball bearings flip flopped while rebuilding it and watching your video helped figure out the issue.
This was probably the best informational video I’ve ever seen. The headset made the narrative so clear and you describe everything perfectly. Now, I have the same problem. I bought a jack at an estate sale and the plug was missing when I bought it. This was an online auction, so it was basically sight unseen. Anyway, the jack won’t lift with the cap and once I remove the cap it will lift if I pump it kind of fast and then once it starts to raise, it will raise to its fullest height. It will sustain that for 24 hours because I had it underneath a wall-mounted cabinet and it didn’t come back down. I have no idea what the brand of my floor jack is. The labels are long gone. The only thing I have a clue about is the fact that it had a Texico sticker on it because you can still see the “T”. So it was at a Texaco refinery or garage, I just don’t know. How in the world am I gonna be able to tell what I have in order to get a repair kit? Any help you can give will be greatly appreciated. Thanks again for a really, really good video.
Thank you for your very nice shout out. Yes that could be an issue. If there are no markings usually there are some stamped markings somewhere or a label but yours may be gone. Send me some pictures I might be able to help. Many of these checks are sold under a different name is, but they’re all very similar. If yours is similar to mine, I will send you the link for the repair kit. Consider subscribing. Thanks, Joe.
I had a Sears 3 ton floor jack that was similar to the model you have there. I bought it in 1988. I lent it to a friend for his engine job. It saw heavy wear & it wasn’t the same afterwards. It limped along for another thirty years & I tried bleeding it & adding jack oil. Nothing seemed to work? I junked it at the town dump. I bought a much better jack from NAPA that’s a hybrid. It lifts quickly until it reaches the vehicle. Then it slows down. It doesn’t weigh nearly as much as the Sears. A much better jack. It will see me out. Thanks for the rebuild video.
Thank you so much. I’ve been saving my dad’s old jack hoping I could figure out a repair someday. Thanks to you I have it out of the barn and rebuild kit on the way
Hey buddy, that is so good to hear. The rebuild is actually a lot of fun and your Jack will be absolutely as good as new for generations to come. I’m glad it was helpful. Consider subscribing. Thank you. Joe.
Wonderful Video, I have an old sears/craftsman 2 1/4 ton floor jack, took it apart, have all the parts in a 5gal oil bucket, now watching your video inspired me to get up and rebuild it it, thank you
Thank you V8skills! I appreciate your comment and I’m glad you found the video useful. I felt a great sense of accomplishment when I rebuilt mine and I know you’ll feel the same way. Consider subscribing. Thanks, Joe.
Thank you so much for your kind words. You will enjoy the rebuild very much and then it’s good to go for at least the next one or two generations. Consider subscribing. Thanks. Joe.
Thanks for this video. I have a similar Sears jack that my dad gave me. It is an odd thing to hold some sentimental value, but it has been in the family as long as I have! We restored cars together and this jack was always there. It stopped holding weight this year and your video gave me a good guide on the rebuild. It works like new again.
Thank you so much for your wonderful comment. I am so glad that was helpful. Isn’t it great when you can rebuild something particularly yours has such incredible sentimental value. That’ll be able to be passed down to the next generation or two. Consider subscribing. Thanks Joe.
Thank you so much for your kind comment. I hope you found it useful. It’s so great when you can put a machine back into perfect working order. Consider subscribing. Thanks. Joe.
I bought a 3 ton Sears jack that was on craigslist for $40 it was completely rebuild professionally he did it because it was his Dad's at the time he spent more than a $100 + shipping at the time -very nice jack i got a bargain
I have the same exact jack that just decided to fail the same way (how dare it after 45 years of reliable service)! LOL I was considering a new one, but it seems even the best of them are all made in China these days. Starting to think it’s best to rebuild this one after watching your video. It’s certainly a well built and reliable tool.
Thank you for your message. Yes I think it’s hard to beat this one. This one is made in Japan and the quality is excellent. The rebuild process is actually quite fun and it will allow you now to have another few generations of use. Consider subscribing. Thanks. Joe.
Bout to rebuild mine in a few mins. Thanks for the great detail in your video. Will make this very easy. I got mine from a good friend that's no longer with us. Almost got rid of it before finding ur video. Now I can continue remembering the good times when I work on the cars.
That’s probably not a bad idea. Remember there are different types of Loctite one is permanent and one is long lasting. I would probably use the long lasting not the permanent one just something to think about. Thank you. Joe.
I hate working on old things. But I love the satisfaction of seeing them work again. Love hate relationships. Now if you could put out a video on getting the old lady to work again. That would be priceless! (I'm kidding!)
Hi Ron, thanks for the comment. It’s a great jack overall isn’t it. They produce so many of those. It’s unbelievable. I’m so glad you’re still works. Consider subscribing. Thanks, Joe.
Thank you so much for sharing with that. That is fantastic. I know you had a great time doing it now you can pass it down to the next generation. Consider subscribing. Thanks. Joe.
It is very enjoyable rebuilding that jack and basically turning it into a brand new piece of equipment that will outlive you. Consider subscribing. Thanks. Joe.
@@JosephHunstad:: the rebuild kit arrived from Amazon a couple days ago. Rebuilding the jack will be my weekend project. My dad bought the Jack new when I was still a teenager, and he, my oldest brother, and I use the Jack many times over the years on different car projects. Have a Lotta good memories of working on my first muscle car, and 68 mustang GT fastback, with both my dad and brother, and using that for Jack. It is an incredibly useful tool.
Excellent Video, I have one just like it only it's orange. Mine is labeled Astro but it's the same. I bought it off the MAC Tools truck about the same time you bought yours, 1981. I had the same problem years ago and since I dealt with a local hydraulic shop they said, "give it to us and we'll rebuild it". They said it's a Hein Werner knockoff. I'd trust it over the cheap ones on the market today. It's sad that all the old hydraulic jack companies are gone. Walker, Lincoln and Blackhawk. These older jacks are definitely worth saving. Subscribed
Thank you very much for your kind comments. It was actually a lot of fun to rebuild and it works great. Yes, these jacks are super well-made and again I think with the rebuild should last another 50 years. Much better than the ones from China. Thanks for subscribing. Take care Joe
Wow, great video, thanks, Dr. Joe! I have what looks like the same jack, but was rated at 2 1/4 tons. I believe I bought it around 1986 at a place called Trak automotive. I have the owner's manual for it, but it doesn't say where it was made, but now I know it was probably Japan. It is just now failing. I'm looking at replacing it for around $200 with an aluminum jack, but now am reconsidering. My hesitation is based on the fact that I don't have any monster vises, along with a few other missing extra large tools. And as you know, Dr. Joe, these things are rather heavy to be muscling around. My back is telling me to proceed with great caution. I do have access to a larger vise, so I might just replace the jack with the intention of doing the rebuild at my leisure rather than giving it to the scrapper. Thanks a lot for posting this. Oh, and I wish I'd seen it before I opened up both of the valve screws on the oil block. I didn't count the threads while backing the needle-valve screw out. Any hope on a home adjustment on that? Again, many thanks for the great video. Cheers.
Wow, great comment! Thank you so much. As far as the valve adjustment I think it’s going to be OK. I would tighten it all the way down and then back it up for turns and watch the function. You probably can’t tell until you repair it how well it works unfortunately. and yes, I needed a big vice to loosen that large nut because it was incredibly tight. I think you’ll enjoy the rebuild. It was a lot of fun for me. Consider subscribing. Thanks, Joe.
@@JosephHunstad Thanks for your quick response and advice. I may order up the kit today and see how it goes. I have a friend who is into vintage vises. And he has heavy shop tables like you have, which would be very handy. I sent him the link here because he has mentioned Wilton vises before. Like you, he's very handy with all things mechanical. Thanks again. Cheers.
Thanks for your comment. It’s a Great Jack made in Japan very high-quality. Once you rebuild, it works great and it’s a pleasure to use. Consider subscribing. Thanks Joe.
Excellent video Joe! Your video on rebuilding this floor jack was very detailed and informative. You didn’t take any short cuts or Mickey Mouse anything. You accomplished a great rebuild on this floor jack. Thanks and BTW I subscribed to your channel and rang the bell(as Scotty Kilmer would say “ring that bell”).
Thank you very much for your kind comments. I hope you enjoy your rebuild. It was a lot of fun and now I have an incredible jacket as good as or better than New. Thanks for subscribing. Take care. Joe.
Thanks for your comment. It’s almost certain that you’ll have a basically brand new Jack that will last for many decades. Consider subscribing. Thanks, Joe.
@@JosephHunstad I'm sure hoping so. It has been many years since I was able to use it. I am about done now and the only problem I found was the main seal. It actually was cracked with a couple of chunks broken off. I was a little short on metric wrenches, but a couple of crescents and a pipe wrench worked okay. And the cheater pipe of course. Not a hard job if one has the tools.
Oh, thank you! I have the same Jack and need to repair it, too. One of the best tools I ever bought. Lost the label years ago, though. Wish I still had it.
finally, I found someone who knows about this particular jack. My father purchased this from Sears when it first came out. It failed last year. That is one well-made jack. Now that I have a video to go along with instructions, I can finally fix it. This is an amazing jack well worth saving and after fixing it, I am sure it will outlive me. I will try to do a video on my repair. Between work, it might be a while. I do have problem. That large flat screw, almost flush to the surface, located on the backside of the pump housing, as shown in your video at 9:14 minutes, you are removing the grooved wheel (not sure actually what's called), to the left, next to the hole opening. On mine, the notch for a flathead screwdriver is worn and frozen. How can I remove that besides drilling it out? I have tried matching the blade the size to give the notch a solid fit, but it just eats the meatal attempting to remove it. Perhaps to use a torch and remove it? That screw is the only thing preventing my repair. By the way. What is that screw for anyways? Any tips or advice on this jack is most appreciated. Thank you.
Hey buddy, great comment. Could you send me a picture of that screw? I have some ideas. Sometimes I’ll take but a Dremel tool with a narrow, grinding wheel and actually cut the groove for the screwdriver deeper and then use an impact screwdriver to get it going, but send me a picture so I can take a look. Thanks, Joe.
Did you have any luck? Sounds like you're speaking of one the screws that say "DO NOT ADJUST". Count and write down the turns needed to take it out, so when you reinstall, you know just how many turns in to go. Like removing a broken exhaust manifold stud, You could (or have someone) weld a nut to that screw head. Once out, cut the nut off and re-slot the screw. Or...just leave the nut on.
@jdh6000 yes. I tore the whole thing apart. Since the time I had asked you about it, my father's old jack works perfectly again. That screw I was careful of. Getting it off was tricky. It was rusted shut. With lots of luck, adjustments, and testing with that particular screw. I was able to dial it in to where it performed well. The only thing left to do and should have done it when it was all apart is to paint it. I am currently looking for a design company that can/would remake new original labels to replace my worn-out ones. So far, it has been a copy right issue and might have to do a little more research to do that or get permission. Overall, this has been the best $50 and change investment I have made. I couldn't have done without your help.
@jdh6000 Also, that screw. The flat head was so beat up. Looks like someone tried to remove it, and there wasn't any slot left to put a Phillips on. I had to spot weld a nut to it and then was able to remove it. I am lucky I have a friend who is a machinist and he made me a replacement.
Hey buddy, it was a lot of fun to totally rebuild it and I know you’ll have the same experience. Let me know how it goes. Consider subscribing. Thanks, Joe.
OBTW- I was almost out the door for a Harbor Freight 3 ton vs the rebuild on this jack. I decided to call HF support and check on rebuild kits. They do not sell any for the jack I wanted.
I have the same jack but its branded by an Australian company so who ever makes them must make them buy the millions and slap on different company stickers. I haven't been able to track down a rebuild kit in Australia so went and bought a new one but am still interested in rebuilding my 20 year old one. Thanks for the rebuild kit link to rebuild mine.
First of all, you are very welcome. The rebuilt kit works great thanks for your interest. I know you’ll enjoy the rebuild. Consider subscribing. Thanks. Joe.
I have 2 of those hydraulic jacks over 45 yrs old One was my dads other I bought like 30 yrs ago Time for me to rebuild them I bought 2 harbor freight jacks in their place. I do this kind of hydraulic wk for a living. Forklift mechanic. Just been lazy. Now watching your video inspired me to get mind rebuilt 😀😀
Thank you for your nice comment. Those old jacks are dramatically better than your Harbor freight replacements. Once you rebuild them, you absolutely have the knowhow, you will be so proud of them and they will last for another couple generations at least. I’ve got a link to the rebuild kits in the description you can just get them that way. It is a lot of fun to rebuild a Jack and have it worked perfectly again. Consider subscribing. Thanks. Joe.
Appreciate the video. I too bought mine in 82-83. I replaced it recently with a Harbor Freight unit but kept this jack around hoping to rebuild it. It is just too well built compared to the new stuff..
You will enjoy very much rebuilding that Jack Yes, it’s well-made. Those were made in Japan interestingly, high-quality, and if you do rebuild it which I highly recommend it’ll be good for another few generations at least. Consider subscribing. Thanks. Joe.
Hey, thanks for your comment. Yes you could use that video to rebuild. If your jack loses pressure once it’s pumped up that’s the time to fix it. It’s a lot of fun to actually repair it as well. Then it’s good for another few generations at least. Consider subscribing. Thanks. Joe.
Thx! Great video instructions. FYI, to remove the hydraulic unit, you don’t have to take all that stuff off. Just the cotter pin and the two side bolts. Raise the lift arm by hand, and then the hydraulic unit then just slips out the bottom.
You should not take at the pressure relieve screw out, it is set from the factory so It don't lift over the rating on the jack. The reason you had trouble taking out the screw was because it was pinned in from the factory. If you look close you can see you can see the center punch mark at the top of the screw... If you have it set to tight it will tear itself up trying to lift more than the rating..
Thank you for your comment Tim. You are absolutely correct. I don’t think I’m gonna try to push this beyond it rated capacity but that certainly could be a problem. Thanks again joe
Hey Desmond, thank you for the nice comment. I’m glad that was helpful. It feels great. Doesn’t it to repair of these things. My old Jack is now my new Jack because it works. Consider subscribing. Thanks Joe.
I loved seeing you rebuild the jack you bought back in '83. I just inherited my grandfather's Sears 2 1/2 ton grey floor jack. I was curious how old it was as he had that thing as long as I remember & I loved helping & messing with it as a kid. Not sure mine needs a rebuild yet as the only issue is it struggles to get the last little bit up so I'm hoping it's just low on fluid. I was surprised to see where the fill plug was located as mine has the slotted plug on the right & a hex plug on the left so I figured those where for filling & bleeding. Anyways now that I know a rebuild kit is available I can be confident that I can pass this on to one of my kids or eventually grandkids.
Hello Larry. Thanks for your comment. It’s great. It’s wonderful to use the jack after the rebuild because it works perfectly. You’re probably going to need a rebuild sometime in the future because it won’t fully lift but if it’s adequate now it’s OK just keep an eye on it because many time is it lifts but doesn’t stay up it will slowly descend, which is dangerous. Consider subscribing. Thanks, Joe.
OK, let me answer your second question first the needle valve. I would basically bottom it out and then back it off six turns that’s a good starting point and will probably be fine. As far as the barbarians are concerned, what I did was identify them as I removed them and replaced them with the same ones. It should be on the video showing exactly which ones go where. I don’t remember off the top of my head right now, but it should be on the video. Thanks for your question consider subscribing. Take care. Joe.
Thank you for your nice comment. I hope you’re able to rebuild the Jack. It would be a good thing to pass out for multiple generations. Consider subscribing. Thanks, Joe.

First off; that is a beautiful Wilton bullet Vise that your keeping clean beside you there. HE...He.. {Oops! there you're using it.} I just missed out on one on my local FB marketplace for an extremely good price. I had a knee jerk reaction to the jack being from Japan, and why put any effort into repairing basically throw away tools. I quickly remembered that Japan does not build tools like China does, in fact they build very good quality tools and electronics. I have an old monkey wards jack that I was considering messaging with a repair on it. Your video has convinced me to do so. Great Video as well as thorough. First video of yours and you got me to sub.
Hello there. You are totally right. Japan makes and has made very high-quality machine goods and instruments. No question. Rebuilding this made in Japan. Jack is absolutely worth the time and effort. You’re basically re-creating a brand new perfectly working tool that will last generations. Enjoy the process. You can get the rebuild kits in the video description. Consider subscribing. Thanks. Joe.
Thank you very much for your comment. It is a lot of fun to rebuild this Jack and yes, it will definitely work for another 50 years. Consider subscribing. Thanks Joe.
If everything else is in good shape as it was here you can consider buying just the piston cup seal to save a few bucks. It's 40mm o.d x 22mm i.d x 12mm thick and it's used on a wide variety of floor jacks including my MAC Tools jack that looks exactly the same.
Hello John. You were absolutely right. I didn’t realize that that was the real issue because everything else is reasonably good. Yes, as it turned out, I could probably have just replace that single part and everything would’ve been fine, but it was good to basically give the jack a complete once over to restore to original. Thanks for your comment. Consider subscribing. Thanks Joe.
I have found that it is safer to replace the old parts the moment I take them out. They will not intermix with other parts and I will not run the risk of placing them in the wrong order. On the other hand, you will save mony buying seals from a seal and bearings store. I took the old ones and they measured them. I paid about $20 for the whole group. Those online kits are way overpriced in my opinion.
@@jpcheco I don’t disagree with you thanks for your comment. I want to replace all the parts including the barbarians, etc. but they’re rarely a problem if ever. Thanks again consider subscribing. Thanks, Joe.
Thank you! for this comment - it saved me a lot of measuring. My same jack has the exact same annoying issue where it won't stay up without load, but will fully support loads. I think that is the same single issue that the jack in this video had. Seems like most of the components are non-wear, or external sealing items, so no need to replace unless there is a leak - even then it's just orings and a couple of pressed-in seals. Thanks again, it should save more than a few bucks, especially considering the copper washers don't fit. Update: just replaced the one seal - it was completely deteriorated - changed it without removing anything from the jack except large nut at top of cylinder and unlatching spring - took 20 minutes including flush with brake cleaner and refill.
I have a vintage Craftsman 1 1/2 ton jack. I think its a 727.12100. Mine pumps up and lift well, but slowly it creeps back down. No outside leaks. Think it needs a rebuild? I will assume watching your video will help me as well. You mentioned Ebay, but I see Amazon links. Great work and you went at a great pace. Thank you for this great content.
Thank you for your question. Yes when you pump up a jack and it’s slowly leaks down that is the number one reason to require a rebuild because basically it’s worthless at this point. The rebuild will fix that problem and the step-by-step instructions in my video will guide you all the way through it. It’s a great joy to rebuild your vintage Jack, and then be able to use it yourself and then pass it down to the next generation. Consider subscribing. Thanks. Joe.
When you have a jack that goes up and back down with the handle when jacking with the jack handle down try taking a small sledge hammer and give the foot that lifts the vehicle a good hit or two straight down 9 times out of 10 it will pop the stuck bearing and work again
Hi Joe. A very interesting and well detailed rebuild video! It's exactly what I need as I have to rebuild my 2-ton Sears floor jack. Am I correct in thinking that you used all of the pieces in the kit, except for the 2 copper washers that were "thicker" than the factory ones? Thanks.
Thank you for your question. No I did not use all the parts. The main cylinder is welted onto the body of the lift mechanism so that didn’t require any seals. Others that that part is separate require an extra O-ring so no I did not use all of the parts. I would say I used 75% of the parts or more. When I looked at the steel ball bearings I couldn’t tell any problems with the ones I had but I did replace them all. Good luck with your rebuild it will go fine. Please consider subscribing. Thanks - Joe
Wish mine still had the plate decals on it, but it faded to metal from sitting outside its whole life. It was my grandfathers, and he didn’t really care about bringing it inside, but it’s still in beautiful shape. Only issue is the cup, that is rusty and pitted beyond fixing, meaning that i had to beat off with a hammer aswell. only has paint on the bottom left.
Thank you for your comment. Yes they’re wonderful Jax. You probably could take that cup and sandblast it and then repaint it and it would look as good as new. Just a thought. Consider subscribing. Thanks. Joe.
Thank you for your question. I’m glad everything is been useful for you what I would do is tighten it all the way down and then back it off six turns as a start see how that works and then possibly adjusted upper down two turns at a time but it probably won’t be necessary. Consider subscribing. Thanks, Joe.
My Sears 2 1/4 is labelled Manufactured for SHINN FU co. of America Inc. In TAIWAN. Very good video. I need more understanding on the adjustment for the factory adjusted screw.
Hi Donald. Good question. If you remove the factory adjusted screw, the best thing to do is to screw it until it stops counting how many revolutions there are. When you reassemble, it screwed all the way until it stops and then back it out that same number of revolutions. That is a good starting point and it’s probably all you need. Consider subscribing. Thanks Joe.
Approx. how many turns do you have in the needle valve screw? Of course I took mine out and didn't realize it was factory set to the correct setting. I believe you mentioned screwing it all the way in and then if counted so many turns back out. Thanks for the video, it's very helpful!
Hey there, I’m glad you tuned into my video. Yes the video goes step-by-step through the whole rebuild kit. It’s actually a lot of fun and then your Jack is basically as good as or better than new and then it will last for another. I don’t know two or three generations. The jacks are excellent and it’s just need for a rebuild which is fully described to your period consider subscribing. Thanks. Joe.
There are many folks that use adjustable end wrenches incorrectly. Iv'e been taught and makes sense, is to flip that wrench over for the direction shown. What it does is it spreads the jaws and allows them to not fit correctly around the fastener.
Well very glad someone is showing how to rebuild these but damn, didn't show pulling the piston rod out and bad main seal? Cmon and what about flushing system before reassembly
Hello Wes, thank you for your comment. Because I already put in so much oil, the quality of the oil in the system was outstanding so I did not need to flush it. Of course if you found the oil was terrible, you’d want to do something other than that. Your comment regarding the piston rod and main seal are very valid. I had already filled this, unfortunately, without any audio, so this is actually a redo to complete the video. Sorry about that. Otherwise I hope you found it helpful. Please consider subscribing.

@@JosephHunstad I just began rebuilding mine, and found a nylon backer washer and an o-ring down the pump rod shaft. Did you change that on yours? If so, which part goes on top in the groove? The o-ring or the nylon washer? It's a PITA to change b/c of the bore being smaller than the 2 parts.
@@JosephHunstad Sorry I don't have a pic b/c the jack is already in service. But if remove the pump rod, and look down the shaft, you will see an o-ring. Anyway, I talked to the tech who sold me the rebuild kit and he told me the backer ring goes above the o-ring. I also lubed the wheel shafts and wheel top bearings with lithium grease (spray). Now my jack works better than when new! Thanks for telling us it was made in Japan and is of high quality.
Your video is the best I've seen so far but I still have some problems with it. I wanted to see how you got the O ring, ring back up and the plunger pump oil seal all in that hole. And I wanted to see which direction of the plunger pump oil seal is up. There is a top and bottom to that plunger seal so which side is up. You don't get directions with any of these kits.
Hello Samuel. Thank you for your shout out and your question. The O-ring and ring back up simply are folded and go into the hole of the pump. And then with your finger you just open those up and they pop in the place inside. The seal is placed so that the flared part is at the end, facing away from the cylinder.. Consider subscribing. Thanks Joe.
Thank you for your comment. Yes I know you’re going to enjoy the rebuild. It’s great when you put it all back together and it works fantastic. Consider subscribing. Thanks Joe.

at 30:12 the flat part of the rotating bar goes down so it spreads the load over a larger area when you're pushing on the piston. The up stroke is a light load by comparison so the round part is loaded less.
Doc, I'm rebuilding and restoring (tore down as far as I can, sanding/painting, etc.) my Dad's 1 1/2 ton jack. Your video helped me A LOT. But under the adjustment screw on the right, all that's up under there a like a rubber 'floor'. I pushed on it a little (very little) and it has some give, but not much. Any ideas? Any help would be greatly appreciated. His borthday is on 12/22, I'm in the home stretch except for knowing what the story is on the adjustment screw.
OK, great question. I would leave that alone because that is a cover of an adjustment screw that was adjusted when the thing was built at the factory. That controls the maximum pressure and the maximum lift and I think you can just leave that B. I did take mine out And readjusted it basically the same setting that it came with. I would leave that alone and not mess with it because it’s already been set. Consider subscribing. Thanks you will love this Jack for many many years you rebuild it. Have fun. Joe
Hello Dr. Joe! I have a very similar jack at home, but it doesn't have any lables for me to identify the exact model. It stopped working so I tried repairing it, but made the mistake of trying to blow out some dust with a compressor, so the small balls flew out. I did my best to find each one, but as I do not know the model, it is hard to know how many balls there should be and how big they are supposed to be. I was wondering if I could send you a picture of the jack somewhere, if you could tell me which model it is and how many balls there should be. Thank you and keep making awesome videos!
thank you for your comment. Yes you probably have lost some of those ball bearings which is actually OK because the rebuild kit will have everything you need. I would recommend getting the rebuild kit that I suggested because I ended up with a lot of extra parts. If you use it, you will have everything you need. Use the number of the Jack that’s on my video and Google it and look at images. You will find an exploded parts diagram that you can use to rebuild your Jack. You’ll have a good time doing it and it will work. Consider subscribing. Thanks Joe. I will have a link in my video description for you to buy that kit and I actually make a few pennies on it but it doesn’t cost you anything more than if you bought it outside of my lake. Thank you thanks for supporting me.
RE loosening the gear in the base @8:17 If you know this is coming off, you can bust it loose before taking things apart. I put it sideways, put on the wrench, and wacked it with a hammer.
Hey buddy sorry about taking so long to respond to your question. You're absolutely right I should've busted it loose before I took it off of the frame. That was certainly made it easier and reduce the step. Consider subscribbing. Thanks Joe
Thanks for your question. You’ve got a good jack. If it fails to hold weight, then it needs to be rebuilt until then it should be fine. Consider subscribing. Thanks. Joe.
Awesome video. I have a different problem with my jack (I have a different one mine is a 3 ton model 875.501153). Mine lifts ok and holds the load up but what it’s doing is as I’m lifting my truck higher it doesn’t go up with a full stroke. The higher it goes the less it lifts. As it gets to about 2/3 of the max lift as I pump the handle down it freely goes down almost all the way and only lifts when your almost at the end of the stroke. It will lift and hold but the higher it gets it takes a lot of pumps of the handle to get the tires off the ground. Do I need a full rebuild or what could be the problem? The jack is almost 30 years old and I bought it new at sears back in the day Thank you.
Hello there. Great question. Funny that it works that way, but it would suggest to me that seal and O-ring replacement would probably benefit or fix that. I’m not certain however. It’s probably the best way to go. I’d be interested in knowing how it turns out. Thanks Joe.
My identical jack is doing the exact same as yours. It bleeds down slowly while I am jacking, but once the saddle gets some pressure on it, it works and holds just fine. Are you saying in the comments, that you feel that the main problem was the light blue colored large piston seal? Nice job by the way!
Yes, it is probably that seal. That’s the most common point of failure. Just be careful if you’re using it and it’s bleeding down it might be risky. Consider subscribing. Thanks. Joe.
Hi Joe, I did subscribe!! I thought that possibly it could be debris/shards where the 2 check balls reside under the metal cap on the valve body. The parts manual calls this the Suction/Delivery Assembly. That said, I bought this brand new in 1975 and I have used it extensively for all of these years. I guess that it does warrant a full rebuild. I may just pull out those ball bearings and check anyway. Has anyone run into this before?
Those barbarians are essential. Be sure you replace those those they’re probably not worn mine were not but the rebuild kit comes with replacement parts anyway so I used the new ones. Thanks.
I think you’ll be able to find it on Amazon. Put the model number in and you should get a number of different repair kits. Consider subscribing. Thanks, Joe.
Hey Joe, I got a reassembly question for you. The "connecting pin" that connects the "fork" pivot to the "pump plunger" has a flat spot on it. Does it go flat side down, or flat side up". I believe flat down to get more surface area. BUT, more surface area means more friction on pump down stroke. Any idea?
If the jack appears to look similar to the jack, I rebuild I believe the kit will be just fine. It actually comes with extra O-rings and seals that allow it to be used on multiple jacks. Consider subscribing. Thanks. Joe.
You ask a very good question. Typically this is set at the factory and I probably should’ve just left alone, but I didn’t so I screw it it all the way in and then backed it out for turns and that seemed to work very well in my case, try that and then you may have to go And unscrew it a little bit more if it doesn’t lower, you would like to consider subscribing. Thanks. Joe.
Hi, good video 👍Question, my Craftsman 214. 12300 three ton jack pumps up a bit and falls flat slowly. I filled the reservoir and bled out all the air prior to it doing what I mentioned and before working on it. Any clues to the problem? Txs
Hey there thank you for your question. It’s undoubtedly one of the seals that has failed. The slow leak is typical and problematic for a seal issue. If you can look up the model number of your Jack, you can probably get a rebuild kit which corrected the problem for me.let me know how it goes. Thanks. Joe.
@@JosephHunstad hi, txs for the reply. A seal? Where do you suspect it is? It's not leaking underneath nor is it leaking on top where there are four holes. i. e. The pump shaft, the next hole, the valve hole and the set screw hole. Do you mean the bottle jack internal seals? Txs
Yes, it is an internal seal. You have to take the pump apart and my video explains that if you watch it you’ll be able to follow it step-by-step and then it’ll be repaired. Thanks. Joe.
Hey Jesse, hope you’re doing well. I actually went on Amazon and put in the part number of the jack and the replacement kit came up. Try that. Consider subscribing. Thanks, Joe.
Hey, that’s a really good question. I’m really not sure but if you’re able to measure the O-rings, you might be able to buy those on Amazon. Thanks. Joe.
@JosephHunstad HI Joe! I am in the middle of this rebuild and have two questions: 1. There are 3 sizes of ball bearings in the kit, so when you refer to the "Large" one I can only guess which one it is. Can you help me as the where the middle size one goes? Also, I neglected to watch your video before starting and failed to not the position of the needle valve. Suggestions where to set it or is it reachable when the jack is reassembled?
Hello sir, I have exactly the same one you have that I bought since 1987 and it just acted like your I wanted to fix it but don't know how. But your channel popped up now I'm rushing to get the kit's and will working on it. Thanks
Hello Tuyen! Thank you for your comment. It was actually a lot of fun to do. Some big tools are helpful as you can see in the video. Let me know how it turns out. I think you’ll have a good time doing it. Believe me at the end when it’s finished and pumps and works great it’s highly satisfied. Consider subscribing. Thanks Joe.
I have the rebuilt kit listed in the video description. You can just click on it and get it from Amazon. It does give me a little royalty, but you pay the same price don’t you don’t pay a penny anymore consider subscribing. Thanks. Joe.
No, that’s true. There are no bearings but what do you need the bearings for? The kid comes with basically all the different types of seals wipes, etc. that will return it to normal functioning, but it doesn’t come with any bearings. I’m not sure where they would go. Thanks. Consider subscribing. Joe.
Hey, thanks for your comment. I have a video on its restoration. You might want to check that out. It turned out to be really great. Consider subscribing. Thanks. Joe.
So many of these jacks were produced with different brands, but they all are very similar and the rebuild kit that I have mentioned in the video description usually works for all of them. That’s what I would try. Consider subscribing. Thanks. Joe.
You know that’s a very good question. I know which gears you’re talking about the pinion gears. I have not looked into that and I do not have a readily available source at this time if I find what I will try to get back with you. Consider subscribing. Thanks. Joe.
Thank you for this video. Very helpful and detailed. One question : what is brand and size of that wrench extension tool you used at time 9:10 of this video. I think I need one of those.
OK the wrench extender that I use I purchased from Lee Valley tools. It is made by the chestnut tool company. It has two very large rare earth magnets that hold the wrench in place. It is very well-made and a very good tool. It’s about $27 I think from Lee Valley.
Dr. Joe - thank you so much. I have just bought one of these tools from Lee Valley and until your video I had never heard of Lee Valley Tools - what a great store and resource. Thanks again.@@JosephHunstad
My leaky Sears 2ton jack is a 328 12041. It looks like the 12160. I can not find a seal kit for 12141. Do you think the 12160 kit would work? I hold you harmless for any opinions.
You ask a great question. Fortunately, the seal kit that I have listed is actually quite universal and comes with extra pieces for many different jacks. I believe that it will take care of your Jack without any issues. Consider subscribing. Thanks. Joe.
It’s a great Jack. These were made in Japan and are very high-quality. If you need to rebuild it, I hope the video is useful. Consider subscribing. Thanks, Joe.
Hello Terry, Although I was unable to find a rebuild kit for the exact part number you listed, there are many such as the following: Floor Jack Seals Kit for Lincoln Walker Model 93642 All Series B C E, 2 Ton If you copy and paste that into eBay, you will find a kit for about $30 that probably will work. It is worth a try as many of these parts are interchangeable and these jacks were sold under many different names. Let me know if that works for you. Thanks. Consider subscribing.
At 32.10. You refer to the "saddle" as the "cup" . Added oil so it would more easily rotate. OK. I am trying to remove the saddle. The "saddle" has a post, which goes in a "hole" thru the metal. The post has a C-clip retainer. (ie. rotor clip, snap ring). Looks like a "C". I remove the C-clip. But the saddle will not lift off. Saddle p/n 2109 Should be simple. What am I missing. Thanks for the quick reply. My jack is exactly like your's. Sear's. 2 ton. Model. 328. 12160
OK I totally understand. That is the part that actually comes in contact with whatever you’re lifting. That should just slide out. It’s not threaded in. If it doesn’t slide out, you should be able to just tap it out with a hammer and a punch. Sorry for my confusion.
Thanks for the quick reply. What you suggested is what I already tried. Will take a closer look with a flashlight. It appears, even with the C-clip removed. The "end" of the saddle post appears to be wider in diameter than the "hole". The saddle does spin around. The "post" is smaller in diameter than the "hole". Just the very end of the post, the diameter is slightly larger than the "hole" so will not slide out. Weird. Thanks . @@JosephHunstad
@@leeozawa OK that is totally weird. I am certain that it just slides in at least in my situation wires white and at the end it’s weird if that is the case you could take a grinder and just grind the edge of it down reducing the diameter or even put some sandpaper on a grinder and sand it so that the diameter goes down but that should just slip in an out and it’s being held by that external retaining ring
Thanks for your advice. Got it out. Not much room to work with . Used a metal chisel. (as a wedge). Lodge in between the bottom of the "post" and the horizontal metal tube. And using a hammer. Gentle taped the end of the chisel, and by pushing in the "wedge" end. The "post" lifted up. Hooray....@@JosephHunstad FYI: Reason for removing saddle. Am in process of installing gas water heater. Younger days, I just lifted it into place. By removing saddle. I plan to attach length of plywood/lumber to the lift. Only have to raise heater about 18", and it weighs about 80/90 lbs. Saw a video, where someone did a similar modification. Again, thanks for the advice. It help a lot !
Used this video to help rebuild the exact same jack. The jack originally was my grandfather's(WW2 vet), then my dad's and now mine. I rebuilt to give to my son. 4 generations of my family will have used the jack and it holds so many memories. I used it to change oil in my first car at 16, I am 61 now. When i touch the handle memories instantly flood back of family members long gone. Thanks for excellent video.
Thank you very much Carlton for your kind words. You made my day. I’m glad you found it helpful. How great that that is now gone for generations. It’ll certainly go many generations to come. The rebuild for me was a lot of fun and I’m really glad that it was helpful for you. Consider subscribing. Thank you. Joe.
this was a well done video Doc. hopefully more people my age will come across your channel and be inspired to fix and repair instead of trashing and buying new.
Thank you very much for your comment. Right now I have 5400 subscribers that I’m proud about and I’m working to grow my channel. It’s really a pleasure and particularly nice to receive comments like yours. Thanks again. Take care, Joe.
Nice. Thank you for the how too video. Much appreciated. I bought mine in 1986. I didn't have much money back then, but I certainly got my money's worth out of this jack. I thought about buying a new jack. Glad I didn't, got the seal kit instead. Now my trusty jack can be passed down to my grandson.
Thanks again!
Hello Mary Mac,
Thanks for your nice comments. Yes enjoy getting that baby going again and lasting for many more generations. Consider subscribing. Thanks, Joe.
Thanks for this video! I got one of these 1.5 Ton jacks when Sears began carrying, I believe it was 1978. My neighbor just gave be another identical as he is moving and installing a lift. These are made in Japan and overcame some of the deficiencies of the Hein-Warner WG model I also have. It is interesting how the adjustable pressure relief in the end of the rod allowed the company to sell the same frame for 1.5, 2.0 and 3.0 jack. My 12002 sold for $99 and the H-W of that time was $500+. Lesson learned. Presumably with higher quality U-seal on the rod. Economical thinking on their part with high part commonality for manufacturing.
My H-W has been rebuilt once and repaired many times. My original Sears 328-12002 model just started dropping the load and the gift 12002 weeps externally. Parts ordered for both. Next is restoration of a 1967 VW engine lift from the VW dealer!! The pump has leaked forever. It looks like a modified transmission jack.
Too much for funnel, switching to syringe . . . . .
Thank you for your very nice comment. You have a lot of experience with those products and I know how much fun it is to have a successful rebuild. Carry on. Consider subscribing. Thanks. Joe.
Thanks for the video! I’ve subscribed. I’ll be rebuilding that EXACT model this weekend, so your tutorial was invaluable. I bought mine new in 1982 when my oldest son was one! I now have three kids and five grandchildren!
Thanks for your nice comment. Enjoy your build that will then last you through your lifetime and probably some generations to follow. Take care joe.
I'm 40 years old and rebuilt my dad's first Sears 1ton floor jack. I wish I watched this video first. Lot of things I didn't do with the kit. But it's working like a champ

Hi Chris, thanks for your comment. Consider subscribing Joe.
In 1980 my dad purchased a Sears 3 ton floor jack and after lifting n lowering several vehicles including a semi truck transmission the jack still works. Amazing craftsmanship. Probably nothing out there made in the USA still to compare
Those Jack’s were made in Japan and very well-made. Yes, they have some seals that will fail but overall their quality and durability obviously is excellent. I’m glad you’re still works great it may need to rebuild someday consider subscribing. Thanks Joe.
Ut would be nice if you would explain how and where one would purchase a rebuild kit!
Excellent video, sir. I inherited this jack from my father-in-law who was a mechanic. Loved using it. I got 2 of the ball bearings flip flopped while rebuilding it and watching your video helped figure out the issue.
Hello John! Yes, you gotta have those in the right sequence. I’m so glad that the video was helpful. Please consider subscribing. Thank you Joe.
This was probably the best informational video I’ve ever seen. The headset made the narrative so clear and you describe everything perfectly. Now, I have the same problem. I bought a jack at an estate sale and the plug was missing when I bought it. This was an online auction, so it was basically sight unseen. Anyway, the jack won’t lift with the cap and once I remove the cap it will lift if I pump it kind of fast and then once it starts to raise, it will raise to its fullest height. It will sustain that for 24 hours because I had it underneath a wall-mounted cabinet and it didn’t come back down. I have no idea what the brand of my floor jack is. The labels are long gone. The only thing I have a clue about is the fact that it had a Texico sticker on it because you can still see the “T”. So it was at a Texaco refinery or garage, I just don’t know. How in the world am I gonna be able to tell what I have in order to get a repair kit? Any help you can give will be greatly appreciated. Thanks again for a really, really good video.
Thank you for your very nice shout out. Yes that could be an issue. If there are no markings usually there are some stamped markings somewhere or a label but yours may be gone. Send me some pictures I might be able to help. Many of these checks are sold under a different name is, but they’re all very similar. If yours is similar to mine, I will send you the link for the repair kit. Consider subscribing. Thanks, Joe.
I had a Sears 3 ton floor jack that was similar to the model you have there. I bought it in 1988. I lent it to a friend for his engine job. It saw heavy wear & it wasn’t the same afterwards. It limped along for another thirty years & I tried bleeding it & adding jack oil. Nothing seemed to work? I junked it at the town dump. I bought a much better jack from NAPA that’s a hybrid. It lifts quickly until it reaches the vehicle. Then it slows down. It doesn’t weigh nearly as much as the Sears. A much better jack. It will see me out.
Thanks for the rebuild video.
Thank you so much. I’ve been saving my dad’s old jack hoping I could figure out a repair someday. Thanks to you I have it out of the barn and rebuild kit on the way
Hey buddy, that is so good to hear. The rebuild is actually a lot of fun and your Jack will be absolutely as good as new for generations to come. I’m glad it was helpful. Consider subscribing. Thank you. Joe.

Thanks for this video. I have a similar Sears jack that my dad gave me. It is an odd thing to hold some sentimental value, but it has been in the family as long as I have! We restored cars together and this jack was always there. It stopped holding weight this year and your video gave me a good guide on the rebuild. It works like new again.

I have the same exact jack that just decided to fail the same way (how dare it after 45 years of reliable service)! LOL
I was considering a new one, but it seems even the best of them are all made in China these days. Starting to think it’s best to rebuild this one after watching your video. It’s certainly a well built and reliable tool.
Thank you for your message. Yes I think it’s hard to beat this one. This one is made in Japan and the quality is excellent. The rebuild process is actually quite fun and it will allow you now to have another few generations of use. Consider subscribing. Thanks. Joe.
Bout to rebuild mine in a few mins. Thanks for the great detail in your video. Will make this very easy. I got mine from a good friend that's no longer with us. Almost got rid of it before finding ur video. Now I can continue remembering the good times when I work on the cars.
I'll probly locktite mine cause the threads feel a little loose when loosening the bolts
That’s probably not a bad idea. Remember there are different types of Loctite one is permanent and one is long lasting. I would probably use the long lasting not the permanent one just something to think about. Thank you. Joe.
I hate working on old things. But I love the satisfaction of seeing them work again. Love hate relationships. Now if you could put out a video on getting the old lady to work again. That would be priceless! (I'm kidding!)
Hey buddy, we can’t always ask for miracles. Have a great day. Take care, Joe.
I'm 77 years old....my mom and dad bought me that jack when I was in high school....probably 1963 or 64. Still works

@@JosephHunstad:: the rebuild kit arrived from Amazon a couple days ago. Rebuilding the jack will be my weekend project.

Have a Lotta good memories of working on my first muscle car, and 68 mustang GT fastback, with both my dad and brother, and using that for Jack. It is an incredibly useful tool.
Excellent Video, I have one just like it only it's orange. Mine is labeled Astro but it's the same. I bought it off the MAC Tools truck about the same time you bought yours, 1981. I had the same problem years ago and since I dealt with a local hydraulic shop they said, "give it to us and we'll rebuild it". They said it's a Hein Werner knockoff. I'd trust it over the cheap ones on the market today. It's sad that all the old hydraulic jack companies are gone. Walker, Lincoln and Blackhawk. These older jacks are definitely worth saving.

Thank you very much for your kind comments. It was actually a lot of fun to rebuild and it works great. Yes, these jacks are super well-made and again I think with the rebuild should last another 50 years. Much better than the ones from China. Thanks for subscribing. Take care Joe
Wow, great video, thanks, Dr. Joe! I have what looks like the same jack, but was rated at 2 1/4 tons. I believe I bought it around 1986 at a place called Trak automotive. I have the owner's manual for it, but it doesn't say where it was made, but now I know it was probably Japan. It is just now failing. I'm looking at replacing it for around $200 with an aluminum jack, but now am reconsidering. My hesitation is based on the fact that I don't have any monster vises, along with a few other missing extra large tools. And as you know, Dr. Joe, these things are rather heavy to be muscling around. My back is telling me to proceed with great caution. I do have access to a larger vise, so I might just replace the jack with the intention of doing the rebuild at my leisure rather than giving it to the scrapper. Thanks a lot for posting this. Oh, and I wish I'd seen it before I opened up both of the valve screws on the oil block. I didn't count the threads while backing the needle-valve screw out. Any hope on a home adjustment on that? Again, many thanks for the great video. Cheers.
Wow, great comment! Thank you so much. As far as the valve adjustment I think it’s going to be OK. I would tighten it all the way down and then back it up for turns and watch the function. You probably can’t tell until you repair it how well it works unfortunately. and yes, I needed a big vice to loosen that large nut because it was incredibly tight. I think you’ll enjoy the rebuild. It was a lot of fun for me. Consider subscribing. Thanks, Joe.
@@JosephHunstad Thanks for your quick response and advice. I may order up the kit today and see how it goes. I have a friend who is into vintage vises.

@@JosephHunstad I'm sure hoping so. It has been many years since I was able to use it. I am about done now and the only problem I found was the main seal. It actually was cracked with a couple of chunks broken off. I was a little short on metric wrenches, but a couple of crescents and a pipe wrench worked okay. And the cheater pipe of course. Not a hard job if one has the tools.

finally, I found someone who knows about this particular jack. My father purchased this from Sears when it first came out. It failed last year. That is one well-made jack. Now that I have a video to go along with instructions, I can finally fix it. This is an amazing jack well worth saving and after fixing it, I am sure it will outlive me. I will try to do a video on my repair. Between work, it might be a while.
I do have problem. That large flat screw, almost flush to the surface, located on the backside of the pump housing, as shown in your video at 9:14 minutes, you are removing the grooved wheel (not sure actually what's called), to the left, next to the hole opening. On mine, the notch for a flathead screwdriver is worn and frozen. How can I remove that besides drilling it out? I have tried matching the blade the size to give the notch a solid fit, but it just eats the meatal attempting to remove it. Perhaps to use a torch and remove it? That screw is the only thing preventing my repair. By the way. What is that screw for anyways? Any tips or advice on this jack is most appreciated. Thank you.
Hey buddy, great comment. Could you send me a picture of that screw? I have some ideas. Sometimes I’ll take but a Dremel tool with a narrow, grinding wheel and actually cut the groove for the screwdriver deeper and then use an impact screwdriver to get it going, but send me a picture so I can take a look. Thanks, Joe.
@@JosephHunstad sure thing. Thank U
Did you have any luck? Sounds like you're speaking of one the screws that say "DO NOT ADJUST". Count and write down the turns needed to take it out, so when you reinstall, you know just how many turns in to go.
Like removing a broken exhaust manifold stud, You could (or have someone) weld a nut to that screw head. Once out, cut the nut off and re-slot the screw. Or...just leave the nut on.
@jdh6000 yes. I tore the whole thing apart. Since the time I had asked you about it, my father's old jack works perfectly again. That screw I was careful of. Getting it off was tricky. It was rusted shut. With lots of luck, adjustments, and testing with that particular screw. I was able to dial it in to where it performed well. The only thing left to do and should have done it when it was all apart is to paint it. I am currently looking for a design company that can/would remake new original labels to replace my worn-out ones. So far, it has been a copy right issue and might have to do a little more research to do that or get permission. Overall, this has been the best $50 and change investment I have made. I couldn't have done without your help.
@jdh6000 Also, that screw. The flat head was so beat up. Looks like someone tried to remove it, and there wasn't any slot left to put a Phillips on. I had to spot weld a nut to it and then was able to remove it. I am lucky I have a friend who is a machinist and he made me a replacement.
I finally got all my parts to rebuild my precious jack. Thanks again for your help and excellent advice.
Hey buddy, it was a lot of fun to totally rebuild it and I know you’ll have the same experience. Let me know how it goes. Consider subscribing. Thanks, Joe.
@@JosephHunstad I will and do a little video with it to send to you.
OBTW- I was almost out the door for a Harbor Freight 3 ton vs the rebuild on this jack. I decided to call HF support and check on rebuild kits. They do not sell any for the jack I wanted.
I have the same jack but its branded by an Australian company so who ever makes them must make them buy the millions and slap on different company stickers.
I haven't been able to track down a rebuild kit in Australia so went and bought a new one but am still interested in rebuilding my 20 year old one.
Thanks for the rebuild kit link to rebuild mine.
First of all, you are very welcome. The rebuilt kit works great thanks for your interest. I know you’ll enjoy the rebuild. Consider subscribing. Thanks. Joe.
I have 2 of those hydraulic jacks over 45 yrs old One was my dads other I bought like 30 yrs ago
Time for me to rebuild them I bought 2 harbor freight jacks in their place. I do this kind of hydraulic wk for a living. Forklift mechanic. Just been lazy. Now watching your video inspired me to get mind rebuilt
😀😀
Thank you for your nice comment. Those old jacks are dramatically better than your Harbor freight replacements. Once you rebuild them, you absolutely have the knowhow, you will be so proud of them and they will last for another couple generations at least. I’ve got a link to the rebuild kits in the description you can just get them that way. It is a lot of fun to rebuild a Jack and have it worked perfectly again. Consider subscribing. Thanks. Joe.
Appreciate the video. I too bought mine in 82-83. I replaced it recently with a Harbor Freight unit but kept this jack around hoping to rebuild it. It is just too well built compared to the new stuff..
You will enjoy very much rebuilding that Jack
Yes, it’s well-made. Those were made in Japan interestingly, high-quality, and if you do rebuild it which I highly recommend it’ll be good for another few generations at least. Consider subscribing. Thanks. Joe.
I am 74 and own the same exact model. Thanks for the video. Now I will know what to do if mine breaks down.
Hey, thanks for your comment. Yes you could use that video to rebuild. If your jack loses pressure once it’s pumped up that’s the time to fix it. It’s a lot of fun to actually repair it as well. Then it’s good for another few generations at least. Consider subscribing. Thanks. Joe.
Thx! Great video instructions.
FYI, to remove the hydraulic unit, you don’t have to take all that stuff off. Just the cotter pin and the two side bolts. Raise the lift arm by hand, and then the hydraulic unit then just slips out the bottom.
Yes, thank you very much for that. You are correct. I appreciate that. Consider subscribing. Thanks. Joe.
You should not take at the pressure relieve screw out, it is set from the factory so It don't lift over the rating on the jack. The reason you had trouble taking out the screw was because it was pinned in from the factory. If you look close you can see you can see the center punch mark at the top of the screw... If you have it set to tight it will tear itself up trying to lift more than the rating..
Thank you for your comment Tim. You are absolutely correct. I don’t think I’m gonna try to push this beyond it rated capacity but that certainly could be a problem. Thanks again joe
I didn't need the video...But glad I watched it...Great job!
I’m glad you found it. Interesting. Enjoy the rebuild. Consider subscribing. Thanks. Joe.

Hey Desmond, thank you for the nice comment. I’m glad that was helpful. It feels great. Doesn’t it to repair of these things. My old Jack is now my new Jack because it works. Consider subscribing. Thanks Joe.
You are doing a wonderful job on it😊
I loved seeing you rebuild the jack you bought back in '83. I just inherited my grandfather's Sears 2 1/2 ton grey floor jack. I was curious how old it was as he had that thing as long as I remember & I loved helping & messing with it as a kid. Not sure mine needs a rebuild yet as the only issue is it struggles to get the last little bit up so I'm hoping it's just low on fluid. I was surprised to see where the fill plug was located as mine has the slotted plug on the right & a hex plug on the left so I figured those where for filling & bleeding. Anyways now that I know a rebuild kit is available I can be confident that I can pass this on to one of my kids or eventually grandkids.
Hello Larry. Thanks for your comment. It’s great. It’s wonderful to use the jack after the rebuild because it works perfectly. You’re probably going to need a rebuild sometime in the future because it won’t fully lift but if it’s adequate now it’s OK just keep an eye on it because many time is it lifts but doesn’t stay up it will slowly descend, which is dangerous. Consider subscribing. Thanks, Joe.
OK, let me answer your second question first the needle valve. I would basically bottom it out and then back it off six turns that’s a good starting point and will probably be fine. As far as the barbarians are concerned, what I did was identify them as I removed them and replaced them with the same ones. It should be on the video showing exactly which ones go where. I don’t remember off the top of my head right now, but it should be on the video. Thanks for your question consider subscribing. Take care. Joe.
Hi Joseph Iam 79 years old and Inheritedmy dad jack I full it with jack oil but it is leaking badly so thank you for your video God bless
Thank you for your nice comment. I hope you’re able to rebuild the Jack. It would be a good thing to pass out for multiple generations. Consider subscribing. Thanks, Joe.
Lots of memories with this jack, I've had mine 35-40 years. It lately has started acting up. Doesn't hold [leaks down] when I have it under load.

First off; that is a beautiful Wilton bullet Vise that your keeping clean beside you there. HE...He.. {Oops! there you're using it.}
I just missed out on one on my local FB marketplace for an extremely good price.
I had a knee jerk reaction to the jack being from Japan, and why put any effort into repairing basically throw away tools.
I quickly remembered that Japan does not build tools like China does, in fact they build very good quality tools and electronics.
I have an old monkey wards jack that I was considering messaging with a repair on it.
Your video has convinced me to do so.
Great Video as well as thorough.
First video of yours and you got me to sub.
Hello there. You are totally right. Japan makes and has made very high-quality machine goods and instruments. No question. Rebuilding this made in Japan. Jack is absolutely worth the time and effort. You’re basically re-creating a brand new perfectly working tool that will last generations. Enjoy the process. You can get the rebuild kits in the video description. Consider subscribing. Thanks. Joe.
I've had mine for 50 years or more. This video should help it through another 50. Probably with a younger person, of course! Lol!
Thank you very much for your comment. It is a lot of fun to rebuild this Jack and yes, it will definitely work for another 50 years. Consider subscribing. Thanks Joe.
If everything else is in good shape as it was here you can consider buying just the piston cup seal to save a few bucks. It's 40mm o.d x 22mm i.d x 12mm thick and it's used on a wide variety of floor jacks including my MAC Tools jack that looks exactly the same.
Hello John. You were absolutely right. I didn’t realize that that was the real issue because everything else is reasonably good. Yes, as it turned out, I could probably have just replace that single part and everything would’ve been fine, but it was good to basically give the jack a complete once over to restore to original. Thanks for your comment. Consider subscribing. Thanks Joe.
I have found that it is safer to replace the old parts the moment I take them out. They will not intermix with other parts and I will not run the risk of placing them in the wrong order.
On the other hand, you will save mony buying seals from a seal and bearings store. I took the old ones and they measured them. I paid about $20 for the whole group. Those online kits are way overpriced in my opinion.
@@jpcheco I don’t disagree with you thanks for your comment. I want to replace all the parts including the barbarians, etc. but they’re rarely a problem if ever. Thanks again consider subscribing. Thanks, Joe.
Thank you! for this comment - it saved me a lot of measuring. My same jack has the exact same annoying issue where it won't stay up without load, but will fully support loads. I think that is the same single issue that the jack in this video had. Seems like most of the components are non-wear, or external sealing items, so no need to replace unless there is a leak - even then it's just orings and a couple of pressed-in seals. Thanks again, it should save more than a few bucks, especially considering the copper washers don't fit. Update: just replaced the one seal - it was completely deteriorated - changed it without removing anything from the jack except large nut at top of cylinder and unlatching spring - took 20 minutes including flush with brake cleaner and refill.
@@JosephHunstad Thanks for the great overall rebuild video. Well done! I learned the specific part I need before tearing down, and how to do it.
I have a Wilton bullet style vice just like yours that’s on your bench. So heavy and high quality.
Those voices are absolutely fantastic. They are a joy to use and it was really fun to restore that. Consider subscribing. Thanks. Joe.
It’s a wonderful vice. Enjoy. Consider subscribing. Thanks, Joe.
I have a vintage Craftsman 1 1/2 ton jack. I think its a 727.12100. Mine pumps up and lift well, but slowly it creeps back down. No outside leaks. Think it needs a rebuild? I will assume watching your video will help me as well. You mentioned Ebay, but I see Amazon links. Great work and you went at a great pace. Thank you for this great content.
Thank you for your question. Yes when you pump up a jack and it’s slowly leaks down that is the number one reason to require a rebuild because basically it’s worthless at this point. The rebuild will fix that problem and the step-by-step instructions in my video will guide you all the way through it. It’s a great joy to rebuild your vintage Jack, and then be able to use it yourself and then pass it down to the next generation. Consider subscribing. Thanks. Joe.
When you have a jack that goes up and back down with the handle when jacking with the jack handle down try taking a small sledge hammer and give the foot that lifts the vehicle a good hit or two straight down 9 times out of 10 it will pop the stuck bearing and work again
Great comment. Next time he gets stuck, I’ll give that a try thanks consider subscribing. Thank you, Joe.
and with that factory screw adjustment. what if it gets moved or been messed with. Is there a reset amount of turns>
Hi Joe. A very interesting and well detailed rebuild video! It's exactly what I need as I have to rebuild my 2-ton Sears floor jack. Am I correct in thinking that you used all of the pieces in the kit, except for the 2 copper washers that were "thicker" than the factory ones? Thanks.
Thank you for your question. No I did not use all the parts. The main cylinder is welted onto the body of the lift mechanism so that didn’t require any seals. Others that that part is separate require an extra O-ring so no I did not use all of the parts. I would say I used 75% of the parts or more. When I looked at the steel ball bearings I couldn’t tell any problems with the ones I had but I did replace them all. Good luck with your rebuild it will go fine. Please consider subscribing. Thanks - Joe
Wish mine still had the plate decals on it, but it faded to metal from sitting outside its whole life. It was my grandfathers, and he didn’t really care about bringing it inside, but it’s still in beautiful shape. Only issue is the cup, that is rusty and pitted beyond fixing, meaning that i had to beat off with a hammer aswell. only has paint on the bottom left.
Thank you for your comment. Yes they’re wonderful Jax. You probably could take that cup and sandblast it and then repaint it and it would look as good as new. Just a thought. Consider subscribing. Thanks. Joe.
Well done. I took apart the presure screw before to part that explains saving the setting can you tell me what number of turns you used on your?
Thank you for your question. I’m glad everything is been useful for you what I would do is tighten it all the way down and then back it off six turns as a start see how that works and then possibly adjusted upper down two turns at a time but it probably won’t be necessary. Consider subscribing. Thanks, Joe.
@@JosephHunstad Thanks for reply.
My Sears 2 1/4 is labelled Manufactured for SHINN FU co. of America Inc. In TAIWAN. Very good video. I need more understanding on the adjustment for the factory adjusted screw.
Hi Donald. Good question. If you remove the factory adjusted screw, the best thing to do is to screw it until it stops counting how many revolutions there are. When you reassemble, it screwed all the way until it stops and then back it out that same number of revolutions. That is a good starting point and it’s probably all you need. Consider subscribing. Thanks Joe.
Approx. how many turns do you have in the needle valve screw? Of course I took mine out and didn't realize it was factory set to the correct setting. I believe you mentioned screwing it all the way in and then if counted so many turns back out. Thanks for the video, it's very helpful!
Yes, I think a good rule of thumb is to screw it all the way in and then back it up six turns and it should be close can I make
I have a Sears floor jack from the 1980’s and it’s painted green. It also doesn’t pump up. I didn’t realize that a rebuilt kit was sold.
Hey there, I’m glad you tuned into my video. Yes the video goes step-by-step through the whole rebuild kit. It’s actually a lot of fun and then your Jack is basically as good as or better than new and then it will last for another. I don’t know two or three generations. The jacks are excellent and it’s just need for a rebuild which is fully described to your period consider subscribing. Thanks. Joe.
There are many folks that use adjustable end wrenches incorrectly. Iv'e been taught and makes sense, is to flip that wrench over for the direction shown. What it does is it spreads the jaws and allows them to not fit correctly around the fastener.
Thank you for your comment. You make a good point. Consider subscribing. Thanks Joe.
Well very glad someone is showing how to rebuild these but damn, didn't show pulling the piston rod out and bad main seal? Cmon and what about flushing system before reassembly
Hello Wes, thank you for your comment. Because I already put in so much oil, the quality of the oil in the system was outstanding so I did not need to flush it. Of course if you found the oil was terrible, you’d want to do something other than that. Your comment regarding the piston rod and main seal are very valid. I had already filled this, unfortunately, without any audio, so this is actually a redo to complete the video. Sorry about that. Otherwise I hope you found it helpful. Please consider subscribing.

@@JosephHunstad
I just began rebuilding mine, and found a nylon backer washer and an o-ring down the pump rod shaft. Did you change that on yours? If so, which part goes on top in the groove? The o-ring or the nylon washer? It's a PITA to change b/c of the bore being smaller than the 2 parts.
I tried to replace every single part. I’m not exactly sure what your part looks like maybe a picture thanks, Joe.
@@JosephHunstad
Sorry I don't have a pic b/c the jack is already in service.
But if remove the pump rod, and look down the shaft, you will see an o-ring.
Anyway, I talked to the tech who sold me the rebuild kit and he told me the backer ring goes above the o-ring.
I also lubed the wheel shafts and wheel top bearings with lithium grease (spray).
Now my jack works better than when new!
Thanks for telling us it was made in Japan and is of high quality.
Hey, that is so good to hear. I know isn’t it wonderful when you rebuild something at a truly is better than new fantastic take care.
Your video is the best I've seen so far but I still have some problems with it. I wanted to see how you got the O ring, ring back up and the plunger pump oil seal all in that hole. And I wanted to see which direction of the plunger pump oil seal is up. There is a top and bottom to that plunger seal so which side is up. You don't get directions with any of these kits.
Hello Samuel. Thank you for your shout out and your question. The O-ring and ring back up simply are folded and go into the hole of the pump. And then with your finger you just open those up and they pop in the place inside. The seal is placed so that the flared part is at the end, facing away from the cylinder.. Consider subscribing. Thanks Joe.
Great job, I have one of these, this video will help, thanks.
Thank you for your comment. Yes I know you’re going to enjoy the rebuild. It’s great when you put it all back together and it works fantastic. Consider subscribing. Thanks Joe.

If I have misplaced the plunger where would I find one or what size is it? Thanks for the video!
So you ask a great question. I am not sure where to find that replacement part. I would have to do an online search or possibly eBay because I don’t think the readily available. Consider subscribing. Thanks. Joe.
at 30:12 the flat part of the rotating bar goes down so it spreads the load over a larger area when you're pushing on the piston. The up stroke is a light load by comparison so the round part is loaded less.
Very good observation. Thank you for your comment. Consider subscribing. Thanks. Joe.
Doc, I'm rebuilding and restoring (tore down as far as I can, sanding/painting, etc.) my Dad's 1 1/2 ton jack. Your video helped me A LOT. But under the adjustment screw on the right, all that's up under there a like a rubber 'floor'. I pushed on it a little (very little) and it has some give, but not much. Any ideas? Any help would be greatly appreciated. His borthday is on 12/22, I'm in the home stretch except for knowing what the story is on the adjustment screw.
OK, great question. I would leave that alone because that is a cover of an adjustment screw that was adjusted when the thing was built at the factory. That controls the maximum pressure and the maximum lift and I think you can just leave that B. I did take mine out And readjusted it basically the same setting that it came with. I would leave that alone and not mess with it because it’s already been set. Consider subscribing. Thanks you will love this Jack for many many years you rebuild it. Have fun. Joe
Hello Dr. Joe! I have a very similar jack at home, but it doesn't have any lables for me to identify the exact model. It stopped working so I tried repairing it, but made the mistake of trying to blow out some dust with a compressor, so the small balls flew out. I did my best to find each one, but as I do not know the model, it is hard to know how many balls there should be and how big they are supposed to be. I was wondering if I could send you a picture of the jack somewhere, if you could tell me which model it is and how many balls there should be. Thank you and keep making awesome videos!
thank you for your comment. Yes you probably have lost some of those ball bearings which is actually OK because the rebuild kit will have everything you need. I would recommend getting the rebuild kit that I suggested because I ended up with a lot of extra parts. If you use it, you will have everything you need.
Use the number of the Jack that’s on my video and Google it and look at images. You will find an exploded parts diagram that you can use to rebuild your Jack.
You’ll have a good time doing it and it will work. Consider subscribing. Thanks Joe.
I will have a link in my video description for you to buy that kit and I actually make a few pennies on it but it doesn’t cost you anything more than if you bought it outside of my lake. Thank you thanks for supporting me.
RE loosening the gear in the base @8:17
If you know this is coming off, you can bust it loose before taking things apart. I put it sideways, put on the wrench, and wacked it with a hammer.
Hey buddy sorry about taking so long to respond to your question. You're absolutely right I should've busted it loose before I took it off of the frame. That was certainly made it easier and reduce the step. Consider subscribbing. Thanks Joe
I have dads Sears jack from years ago. Our jack is Orange an still works fine but i might need this?
Thanks for your question. You’ve got a good jack. If it fails to hold weight, then it needs to be rebuilt until then it should be fine. Consider subscribing. Thanks. Joe.
Awesome video. I have a different problem with my jack (I have a different one mine is a 3 ton model 875.501153). Mine lifts ok and holds the load up but what it’s doing is as I’m lifting my truck higher it doesn’t go up with a full stroke. The higher it goes the less it lifts. As it gets to about 2/3 of the max lift as I pump the handle down it freely goes down almost all the way and only lifts when your almost at the end of the stroke. It will lift and hold but the higher it gets it takes a lot of pumps of the handle to get the tires off the ground. Do I need a full rebuild or what could be the problem? The jack is almost 30 years old and I bought it new at sears back in the day Thank you.
Hello there. Great question. Funny that it works that way, but it would suggest to me that seal and O-ring replacement would probably benefit or fix that. I’m not certain however. It’s probably the best way to go. I’d be interested in knowing how it turns out. Thanks Joe.
Fluid may be low.
My identical jack is doing the exact same as yours. It bleeds down slowly while I am jacking, but once the saddle gets some pressure on it, it works and holds just fine. Are you saying in the comments, that you feel that the main problem was the light blue colored large piston seal? Nice job by the way!
Yes, it is probably that seal. That’s the most common point of failure. Just be careful if you’re using it and it’s bleeding down it might be risky. Consider subscribing. Thanks. Joe.
Hi Joe,
I did subscribe!! I thought that possibly it could be debris/shards where the 2 check balls reside under the metal cap on the valve body. The parts manual calls this the Suction/Delivery Assembly. That said, I bought this brand new in 1975 and I have used it extensively for all of these years. I guess that it does warrant a full rebuild.
I may just pull out those ball bearings and check anyway. Has anyone run into this before?
Those barbarians are essential. Be sure you replace those those they’re probably not worn mine were not but the rebuild kit comes with replacement parts anyway so I used the new ones. Thanks.
My Dad left us a 2 ton one that looks just like it
I might try to fix it if I can find the correct kit
I think you’ll be able to find it on Amazon. Put the model number in and you should get a number of different repair kits. Consider subscribing. Thanks, Joe.
Hey Joe, I got a reassembly question for you. The "connecting pin" that connects the "fork" pivot to the "pump plunger" has a flat spot on it. Does it go flat side down, or flat side up". I believe flat down to get more surface area. BUT, more surface area means more friction on pump down stroke. Any idea?
Good question but the flat part I believe is down and that’s how I reassembled mine
I damaged the round metal ring of the plunger. Amazon repair kit did not include the ring. Where can I order the item?
I’ll do my best to help you. Could you please send me a picture of that part that’s damaged thanks, Joe.

I did not see how you set the pressure relief valve. The screw on top of the jack body on the right side. How do you reset the valve relief pressue
You ask a very good question. Typically this is set at the factory and I probably should’ve just left alone, but I didn’t so I screw it it all the way in and then backed it out for turns and that seemed to work very well in my case, try that and then you may have to go And unscrew it a little bit more if it doesn’t lower, you would like to consider subscribing.

Hi, good video 👍Question, my Craftsman 214. 12300 three ton jack pumps up a bit and falls flat slowly. I filled the reservoir and bled out all the air prior to it doing what I mentioned and before working on it. Any clues to the problem? Txs
Hey there thank you for your question. It’s undoubtedly one of the seals that has failed. The slow leak is typical and problematic for a seal issue. If you can look up the model number of your Jack, you can probably get a rebuild kit which corrected the problem for me.let me know how it goes. Thanks. Joe.
@@JosephHunstad hi, txs for the reply. A seal? Where do you suspect it is? It's not leaking underneath nor is it leaking on top where there are four holes. i. e. The pump shaft, the next hole, the valve hole and the set screw hole.
Do you mean the bottle jack internal seals? Txs
Yes, it is an internal seal. You have to take the pump apart and my video explains that if you watch it you’ll be able to follow it step-by-step and then it’ll be repaired. Thanks. Joe.

@JosephHunstad HI Joe! I am in the middle of this rebuild and have two questions: 1. There are 3 sizes of ball bearings in the kit, so when you refer to the "Large" one I can only guess which one it is. Can you help me as the where the middle size one goes? Also, I neglected to watch your video before starting and failed to not the position of the needle valve. Suggestions where to set it or is it reachable when the jack is reassembled?
one more question. what purpose does that needle valve do for the jack? Thank you

I have a sears 3 1/2 ton 214.50136 would this be the same. I've noticed that all the rebuild kits for it that none come with new bearings.
No, that’s true. There are no bearings but what do you need the bearings for?

Do you think the 12160 kit would work? I hold you harmless for any opinions.
You ask a great question. Fortunately, the seal kit that I have listed is actually quite universal and comes with extra pieces for many different jacks. I believe that it will take care of your Jack without any issues. Consider subscribing. Thanks. Joe.
@@JosephHunstad Main seal worked,. Plunger seal is too small. All USA made. Name plate is metal.
My kit came in a shrink wrap shirt board.
Have same jack. Bought in early 70's
It’s a great Jack. These were made in Japan and are very high-quality. If you need to rebuild it, I hope the video is useful. Consider subscribing. Thanks, Joe.
I can’t find a kit for my Lincoln 2 ton jack H680041S2. Can you recommend a source. It’s Chinese made. Thanks for the great video.
Hello Terry,
Although I was unable to find a rebuild kit for the exact part number you listed, there are many such as the following:
Floor Jack Seals Kit for Lincoln Walker Model 93642 All Series B C E, 2 Ton
If you copy and paste that into eBay, you will find a kit for about $30 that probably will work. It is worth a try as many of these parts are interchangeable and these jacks were sold under many different names. Let me know if that works for you. Thanks. Consider subscribing.
@@JosephHunstad Thank you.
At 32.10. You refer to the "saddle" as the "cup" . Added oil so it would more easily rotate.
OK. I am trying to remove the saddle.
The "saddle" has a post, which goes in a "hole" thru the metal.
The post has a C-clip retainer. (ie. rotor clip, snap ring). Looks like a "C".
I remove the C-clip. But the saddle will not lift off. Saddle p/n 2109
Should be simple. What am I missing.
Thanks for the quick reply.
My jack is exactly like your's. Sear's. 2 ton. Model. 328. 12160
OK I totally understand. That is the part that actually comes in contact with whatever you’re lifting. That should just slide out. It’s not threaded in. If it doesn’t slide out, you should be able to just tap it out with a hammer and a punch. Sorry for my confusion.
Thanks for the quick reply. What you suggested is what I already tried. Will take a closer look
with a flashlight. It appears, even with the C-clip removed. The "end" of the saddle post appears to be
wider in diameter than the "hole".
The saddle does spin around. The "post" is smaller in diameter than the "hole". Just the very end of the post, the diameter is slightly larger than the "hole" so will not slide out. Weird.
Thanks . @@JosephHunstad
@@leeozawa OK that is totally weird. I am certain that it just slides in at least in my situation wires white and at the end it’s weird if that is the case you could take a grinder and just grind the edge of it down reducing the diameter or even put some sandpaper on a grinder and sand it so that the diameter goes down but that should just slip in an out and it’s being held by that external retaining ring
Thanks for your advice. Got it out. Not much room to work with
.
Used a metal chisel. (as a wedge). Lodge in between the bottom of the "post" and the horizontal metal
tube. And using a hammer. Gentle taped the end of the chisel, and by pushing in the "wedge" end.
The "post" lifted up. Hooray....@@JosephHunstad
FYI: Reason for removing saddle. Am in process of installing gas water heater. Younger days, I just lifted it
into place. By removing saddle. I plan to attach length of plywood/lumber to the lift.
Only have to raise heater about 18", and it weighs about 80/90 lbs. Saw a video, where someone
did a similar modification. Again, thanks for the advice. It help a lot !
@@leeozawa hey man great to hear it. Glad everything worked out well. Good luck with your hot water project. Take care Joe.
I have an opportunity to purchase one of these jacks. Can you tell me the size of the hole that the saddle drops into?
I am out of the country currently I’ll have to measure it then I’ll let you know consider subscribing. Thanks, Joe

also the copper washers or seals are crush seals being copper.. They need to be crushed down a little to seal right.
Yes, good comment. Thank you very much.
