Can I send just the bottle Jack to rebuilt it , what is the address i send it , so I have to find out how can I send it through a less expenc. due to my stroke my right hand has no power & right knee is replaced & I can not bend it to knee down 😂 but happy
@@BernFricke I worked a hydraulic shop I Odessa Tex in the late 70s early 80s. Just the 2 of us did right at 300,000.00 a year repairing these old tools. Once the Chinese junk flooded the market no one paid to have good American made equipment repaired. Glad to see this channel up and running.
I don't even have a hydraulic jack but nothing beats a thorough rebuild instructional video. Didn't know floor jacks were just horizontal bottle jacks 😂
See that he went from hydraulic jack repair to dog medic without even skipping a beat. Proof that this man can do almost anything! Great video Moe, thank you!
Im a retired auto mechanic and over the years I've done countless teardowns and assemblies, but after seeing this i know ill just buy a new jack if my old one quits working. Hey im 63 and i dont need the hassle, i want as much non-mechanic time i can get while im still around. But you know your stuff.
Most new jacks are craaap! I’d rather rebuild an old timer. I mean you can always find an hour or two where there’s nothing to do, especially being retired.
@@billmellater the problem with that is most rebuild kits are also craap unless you find new old stock that wasn't made in China India etc. their rubber O-rings/seals are junk
Your older jack has a lot of life to give, when you buy a newer likely worse jack that easily fits your needs you can sell it cheap to someone who wants to fix it and will treasure it for years to come, this is a great service
65 here. Used to use ramps but the 94 Mercury Cougar I inherited hits the lower front end before the tires head up the ramp. I have old snap on jack that has been sitting under trees for over 10 years. I here the new ones are 1000.00. I bought a low profile pittsburg at 60.00 off for 100.00. I think it would have cost a lot more than that to repair the snap on. I only use a jack for oil changes once a year. I'm sure someone would really love to have the snap on for repair.
Great video and fixed my Jack! I want to let you know you did two things in the video. You taught us how to rebuild it and how and why the Jack works. 99% of people don’t care how it works, we only want it fixed. LOL
I’ve got a (nice at the time, Craftsman) Jack that I used to use in the late seventies when I did my own work on my cars. It hasn’t worked in ages, and I’ve been convinced it could be repaired easily enough! Thanks for sharing; everyone says “they’re cheap, just buy another one “, but I’m not that guy… fix it is my motto
I agree with that. If I can fix something, that's what I would rather do. For some reason, I didn't think to take my Jack's apart to see if I could repair them. Now I will.
@@Guillotines_For_Globalists That's one of the easiest things to fix In fact he is fixing stupid through the cumulative effect of his vids. He is not only showing us how to fix / make stuff, he is showing how to approach solving problems and to think outside the box (which is EXATCLY how to "fix stupid"). Now, hopefully you are smart enough to stop spreading the "cant fix stupid" idea... cuz it is a remarkably...well ... stupid meme (I'm not saying your stupid, just that the idea is - cuz "stupid" is so ridiculously easy to fix, and happens to basically everyone on the planet as they grow / learn ... (Now I suspect I should BFI)
Nicely done! I have a 30 year old HF cast-iron beast proly 80lb, still works fine. Holds a load fine. Sits out in the rain and snow so the star wheel is hard to turn. Bought in a box full of returned HF tools. I'm guessing the reason why it was returned is because only three of its wheels touch the ground. It has always worked just fine. Advantage is the same as a pine wood derby race car, less rolling resistance. LOL! No issues lifting my GMC K2500. Thank you for the video, always more to learn.
The blue Lincoln jack at the beginning i worked for that company for many years. One oddities in the pump seals cylinder. Leather v-cup washers are used. Everything we tested leather was the only one that held up. Rubber plastic etc. Wipe the cylinder clean of oil on the back stroke. Leaving it dry for next stroke.
I rebuilt all my jacks, this video is a good brush-up on the procedures and is appreciated. The big RED you have is a copy (?) of an all-construction cast iron Blackhawk 3-ton 1945 vintage (mine) which I have and rebuilt, they used v-packing for the seals back then which I retained. It is a 2-speed, Fast upstroke until it senses a load then reverts to 3/4 inch up increments, with a 24-inch lift. It even has a key lock in the handle knob as a safety measure to prevent opening/closing the valve and a battery-powered front light to see in dark places wherever you roll the jack under, cool or what!! It is a heavy beast but a beautiful antique jack. Again thanks for the video.😎
I like the fact that there are others who's garage is pretty messy but can still get shit done. I also got a really nice commercial Hein Warner floor jack at a yard sale for $25. She works but leaks, will need to do the same re-build. Thanks!
Thank you! I am a learner and i was afraid to take apart a car jack because i did not know what to expect, but after watching this video after few hours i fixed two car jacks in my uncle's workshop that have been laying around broken and unused for years!! Spending only 11$ !!!
@@timscott2329 it's all metal and rubber, so the rubber is the thing that falls apart. All i had to do is replace the seals. Some were clearly broken in pieces and some could still work but i replaced all because it's very cheap to do so. I discovered that some jacks have the main seal made in teflon: these require heat to be both put in place or removed.
PERFECT! Solved my problem. My trolly jack all of a sudden would not lift very high and even then it would deflate upon its own weight. My jack is 30 years old and when buying the hydraulic oil I had a choice between AW-32 or AW-46 ("W-46 which is thicker and less likely to leak from an older machine") I drained the old oil and followed your video - 10/10 - Thanks!
I work offshore in oil production. We use charcoal lighter fluid to clean parts, slowly switching to using it at home as well! Great vid, on showing how to repair/rebuild!!!
Interesting. I'm pretty sure charcoal lighter fluid is naptha. I know my favorite concrete degreaser has a lot of naptha. Never really thought about it as a parts cleaner but it makes sense.
@sixtyfiveford the lighter fluid with naptha you're thinking of is zippo lighter fluid great degreaser but evaporates quickly charcoal lighter fluid is closer to kerosene or lamp oil
I've noticed that super cheap lighter fluid smells like diesel fuel. It makes the food taste horrible. Don't know if it's actually diesel fuel or not. If it is, then wouldn't that destroy some seals? Or is diesel fuel only harmful to gasoline style gaskets?
I repaired an old BRADBURY jack of my fathers, probably 1950's. Had the seals custom made. Quite a simple but super robust, powerful jack. Works really well now.
If you have a shop press with a pressure gauge, then you can easily readjust the pressure relief valve under the orange cap. When I overhauled my 2.5T floor jack, I found loose casting sand inside, so I completely disassembled the jack to clean it all out. After reassembly, I put the jack in the press, extended the arm up to the press ram, then used the press to push down on it until the pressure release valve in the jack let go to get a pressure indication, being careful not to allow it to exceed 3 tons. Adjusting the valve, I was able to reset the check ball to release between 2.5 and 3 tons.
Thanks friend for making us ones that never throw anything away glad we kept our stuff around to fix cheap someday. Btw ironically my Australian shepherds shoulder is also jacked up, been going on & off since this past August I even spent $360 on an x-ray that didn't show anything but eliminated some of the unknowns, I guess next step will be an MRI, he's my 8-year-old boy, (only child) so damn the cost!! ✌️
Yeah this has been going on since at least the beginning of summer. I'm assuming it's a torn muscle or something. Dogs just don't know how to let stuff heal though and take it easy. I thought about splinting it up so she just limped around and didn't use it but then likely she'd hurt the other leg.
I only watched this as I have a Jack that looks just like the Coats Nike with the exception of the wings for the castor wheels being pressed not cast and the handle has a quick release plunger not a pinch bolt. I re-sealed the pump on mine and blasted and painted the whole thing as it was mostly missing all its paint, it also benefited from getting all the pivots out and freed up so that they stay static in the frame and the arms rotate on the pin as they were turning in the frame when I got it. I will have to investigate mine as I think it might have the speed lift, from memory the valve body has the extra port, but it definitely doesn’t seem to work and it would be real handy if it did!
@@sixtyfiveford If the doggo doesn't have a bona fide injury but rather a strain or hyperextension kind of deal going on... you're going to have to just lock her up for a good couple of weeks to a month. And I mean so she cannot run or chase at all. That's about the only way to get things healed up because the dog is going to do what dogs (and KIDS!) do which is to keep right on going and that often leads to an injury never healing up or worse. What's worse? A permanent injury. BT & DT a few times over the decades. Including to myself as a teenager until I was forced to cease all athletic activity by my parents until I healed up and was cleared by the doc. Hey! I could still catch a football even with a cast on my arm?!? Best wishes! - Max Giganteum
What a great deal on that heavy duty jack. I fished a 2.5 or 3 ton, can't remember, jack outta the dumpster a while back. It's an older, made in japan orange jack in great shape except for a missing handle. I have the rebuild kit, just haven't taken time to do it yet. Thanks for all your useful, informative videos!
Thank you so much! I’m old but never really learned how stuff works until recently… honestly never really cared until I became so broke (long story) I need to repair things myself! Seriously thank you from an ignorant old man trying to get educated!
Where do you get rebuild kits for harbor freight 3 ton jacks thanks I’ve been wanting to learn how to rebuild my floor jacks for 35 years instead of throwing them away
Ginger has been with you a long time. she starting to get a little older and she's so very active. that she needs a little muscle massage every now and then. she's such a great shop companion. this was a really comprehensive video on rebuilding floor jacks. you covered all bases another great video as always. thanks for all the great work you do.
My 6 year old 3.5 ton Napa jack failed on me last week. Glad I had the side by side blocked . No oil leaks so will look at the check valve components. Great video. Your explanation on hydraulics was perfect.
Excellent video, have a Lowes Kobalt 3T that pumps occasionally when it feels like it. Talked to two hydraulic shops and they said that they are throw away. It looks identical to your Craftsman 3T. Think I'll try taking it apart completely this time, last time just replaced the O-ring at the top of the canister and verified that the cup seal wasn't damaged. Think now one of the ball checks are sticking and/or dirty.
I have the Craftsman 2-ton. Its around 40 years old. It survived my brothers abuse and is still working fine. I was at a friends house. His jack would not roll. When he stepped away, I oiled the wheels. Took a while to work, but was rolling by the time he came back.
Nice, thanks! I have an old jack in the garage, friend said it stopped going down. Haven't looked at it too close yet cause I didn't really know what I was up against. I think this will motivate me to go look at it
I worked for a shop in east Dallas that rebuilt auto mechanic tools of all kinds. If a tool truck sold a tool to a line teck at a dealership; we would rebuild that tool when it needed it. There were about 4 shops around Dallas that did the same thing - this was in the early 80's. Brought back a lot of memories; while watching your vid my imagination was smelling all the oil/grease smells I experienced. Working at this shop was a few years before Harbor Freight and their cheaper tools from china became popular. Line techs only bought CN, Ingersol'ran, or Snap'on back then. With the floor jacks, the dealer's mobile battery jump start equipment, and air tools - we were always busy. I got pretty good w/the 20 ton floor jacks. We had a test stand that went up into the 60/70 ton range. The test for the floor jacks was 24hours at the jack's maximum w/out any bleed down on the test stand. I had 2 of those floor jacks seal cup blow out while on the test stand as I was walking by them, talk about getting all shook up. Of all the jacks I rebuilt I only had one that couldnt be rebuilt. I rebuilt it 3 times and it always leaked down on the test stand. The boss even rebuilt it once; said w/his 30 years experience he's never had a jack that couldnt be rebuilt - no telling what that jack had been thru; if only that jack could talk. Thx for the vid. Brought back a bunch of memories
I have a small yard sale jack that needs seals. Great video! Thanks I hope Ginger is quickly recovered. One of my 4 dogs turns 13 today. We got the word back from his $513 vet visit last week that the tumor on his belly is malignant and is scheduled for surgery on Dec 27. $900 more cost. Merry Christmas Jethro the Chihuahua, you will be biting ankles for a few more years! Get well Ginger!
Dang, I wish you the best. It'll be well worth it. Expensive but I wish human health care cost this little. I can't even imagine how much they charge to remove a tumor from a human.
@@sixtyfiveford Dogs are worth it. They provide unlimited love. Vet said we caught it early. Testing & X-rays show he has clear lungs and good heartbeat. I save money by doing my own repairs on stuff, so I have money for things like rescue dogs. A Chihuahua, a Yorkie mix, a Boxer mix and a Pittie mix all share our house with the two cats.
I love how you take us through a project with plain english and simple guidance! The check valve layout that you did was super helpful! I thank you for sharing! Then, at the end, when your furry relative had the hurt paw, you had me saying awwwww. Nice video!
Thanks for sharing! I have a jack that is acting up and another that i retired and just havent thrown away yet. I will be rebuilding them now. Thank you!
I fixed one of my jacks by refilling it with ATF stop leak in ~2008…it had a leak, lost almost all the oil, so I did that. It still works, now. I don't use it as much because the wheels are loose, but I can't throw it away because it works, and hasn't leaked or sank since my "repair"…from an open bottle I found in my garage. It may not work for your jack, but it might be worth a try.
@@michaelbrinks8089 good tip Michael. Scotty Kilmer endorses this product. Don't know if its available here in Australia. We get most stuff I see in the States, Lucas etc. Regards Bruce
Thank You for this video. Several years back we bought a military jack of about that size to R&R the transfer case from the M925 6X6 we bought. It was a bit leaky but did the job, plus I have 2 HFT hydraulic tables to rebuild. Plus 3 bottle jacks that were my fathers. Now I know what measurements I need to fix all of these.
I never realized, until watching this video, that these would lend themselves well to being turned into hydraulic presses compared to smaller bottle jacks. That T bar would be useful. I'm going to keep that in mind when I have to build a press later on.
Nice work on the jack and a killer deal. Working at UTC I discovered a problem. The hydraulic presses were built to run at 3000 psi. The plant manager wanted to speed up the presses so he had the pressure raised to 3500 psi so they could accept 9 inch billets instead of the 6 inch they were designed to push. . The plant was built in 1951 and the owners were scrap dealers so all the equipment was second or fifth hand by the time they got it. The maintenance men were OJT and no one was trained how to train them. The lines were springing leaks all over. Every fitting was extruding the o rings through the gaps between the flanges. I thought at fires it was the increased pressure. I turned down the pressure as an experiment. The lines were still blowing out the o rings. I checked and the stock of o rings were made from 70 durometer rubber used for air and water lines I replaced them with 90 durometer o rings for hydraulics and stopped the problem of the o rings failing. Sounds like a win right? With the high pressure o rings not acting as a blow out plug the presses ran with the 3500 psi oil pressure but the 10 ton cast iron platen on the 1600 ton Youngstown extrusion press cracked in the middle. It took 3 months to get a new one made by Youngstown. Solved one problem and made another. Give Ginger a pat for me.
Grand Central! On State Street! I loved that place .. When I was a kid we hit the one with the round roof (arched front) .. Too fun .. Some turned into Fred Myer's .. Off to work on my dad's jacks :) .. he's got one of those biggies that've been down for the count for decades .. I need the brand and I'll order him the orings and u-seal ..
Very NICE training We have three foor jacks that have that disease of not holding the weight when extended !! I will have to remember this video when I get to it!!
Very well done video. I've been wanting to rebuild mine for years... It's so helpful to understand the function and guts before tearing into it. Much appreciated.
I must have 3 or 4 floor jacks hidden under work benches. ,, Guess it's time to buy a kit or two and put them back in service. Thanks for sharing your knowledge.
Some of the more common jacks you can buy a whole kit for around 25 bucks. That's not bad considering the cheapest 3ton jacks or well over 100 nowadays.
I have and still use that same, beefy Japan made blue hammer finished Craftsman 2 1/2 ton jack. Also have a matching mint screw type differential jack (made in Taiwan). I hurt the Craftsman as it was low on oil and the internal screw was semi-dry making it stick. We always forced it loose with the handle. I disassembled, scrubbed, polished and lubed it completely about 4 years ago.
Very informative video. I had a problem with handle kick on a small jack, almost never used. Hearing that the return valve is gravity activated led me to fixing it by turning the jack upside down to oil the valve-ball end then knocking around the master cylinder with a small hammer to get the ball moving. The jack now works flawlessly. I didn't find this solution anywhere, but wisdom is power! My guess is, that setting the jack aside in the case it is delivered in, where it is actually standing on its side is not helping things.
Great video !!! Most importantly is the trust that dog has in you !! No doubt you have been good to her !! I like the way she jumps up to let you ease her discomfort. Amazing Dog she is and not enough said for her owner !! Thanks again for the video on the hydraulics of a bottle jack and really how simple they are to rebuild.
Probably the best info video I’ve seen. Your pace is perfect, your explanations are great, and your camera work is outstanding! Thanks for your work putting this together. I’m sure many guys will benefit from this. Well done! ❤
Great demonstration on how hydraulic jacks work. Where do you get the diagrams? I have several non working dump pick jacks missing handles, wheels and the plate that pushes up the vehicle that I plan on piecing together to get at least one good one. The rest I have plans to refabricate into other tools. Adding another 👍. Hope Ginger heals soon. Stay well, Joe Z
Thanks Moe. I watch all of these hydraulic repairs that I can. If you own hydraulic jacks you WILL, some day, need to overhaul one. Tell Ginger that Tater Tot said WOOF !! That jack is not the only thing that has trouble staying up........ oops ! Did I say that out loud ?
Those Walkers are great jacks. The catch 22 of living in America is we can't afford to have fellow Americans work for us. It's cheaper to buy new. I messed around with this for 3+ hours. At a shop rate these days of $180++++ and marked up parts prices, this could have easily set someone back $700-800 in repairs.
Great knowledge, great video - it's unlikely that 99% of us will ever strip a complex 30 tonne jack. Would you consider making a video of a standard, budget 3 tonne floor jack strip down, check and seal replacement? That would be really useful.
Craftsman used to sell a compact high lift 2 ton with the rapid extend. It was my favorite Jack until i used it under water and the high speed went away. Maybe it's time i tried opening it and seeing if it just needs a new ball in the high speed check. I thought it would be more complex so i never opened it. I probably broke it in 2009, still use it today
Awesome video on the inner working of hydraulic jacks. Hoping to figure out why my hardly used cherry picker only pumps a half stroke. I added fluid as it was low. Before adding fluid it wouldn’t pump up at all. After seeing this I think I will remove it and fill it with the cylinder laying down horizontally. Hopefully that works. You’re amazing, love your content. Thank you for sharing this
Air bubbles can be a pain. Sometimes laying the jack on it's side with the pump down(that's where it will pick up oil) will allow air bubbles to flow out into the reservoir
You are amazing man, very talented in your ability to explain things with your pictorials and large scale visuals like the pipe with the pool table ball. Thank you.
I bought a cheap floor jack around 25 years ago and it still works; I think because I bought a bottle of hydraulic fluid and topped off the fluid immediately when it was new. My brother claims his just failed in a MUCH shorter time. They don't like to ship them with lots of fluid, I guess, so you need to top up the hydrolic fluid in your new one if you want it to last. . . or you will end up doing something like this . . . much too early!
I like to take an air powered bottle jack and put them in there and use it that way just because it's faster,it still works really well if you have time for the modification.
Best teardown and repair video I've seen so far. My 2 ton engine hoist/lift stopped working. It required further and further tightening of the release valve for it to work. Now it feels like it goes mooshy inside. Like maybe the seat of the ball split open or something. Can it be replaced?
MM77 Approved 👍🏼👍🏼……………………………………………………………………Very good explaining how a bottle jack works. I felt like I was back in hydraulics class , I mainly remember the instructor used to say “ Flow makes it go”. He was retired US Navy sailor who was on carriers and worked on the catapults. That man had some STORIES !! LOL
Thanks Moe for sharing your knowledge on floor jacks and their repairs. The only thing is that I’m not sure if there’s an available kit to repair mine. But maybe I’ll do what you did and just try to match the seals from a kit.
The COATS NIKEE jacks as we spelled it at the shop were sold by both by Snapon and Coats FMC the makers of the tire machines. My dad & grand father bought a coats machine the bubble balancer new in 1967 it came as a package deal the jacks were sold separately. I think they paid a total of like $1,700 for the machine and balancer the jack was like another $200 bucks. If I am correct there was a bubble balancer for car tires and a larger one for light truck tires.
Love the video! Hope your pups paw is healing up. I do have a few jacks some I'm not using because they Creep down when having weight on them. And most have age but not used like in a shop everyday. And idea or just a total seal replacement like in your video.
Help, no sane person would put as much effort into this as I am. I keep reviewing this and other vids, but this is most educational. I finally understand that check valve ball, I was going to ask how to set it (most just say tighten and back off), but I think I get that (I had it al t he way down and that may have been preventing all fluid from entering, so nothing worked. My Craftsman is weird though, it's got like a sealed screw, covering the screw that holds the spring/ball. That seal (flat/square o-ring, not just o-ring) might be the culprit. I'm trying to rule everything out prior to complete disassembly. Air is entering somewhere as I KEEP successfully bleeding, but with any movement, air returns and another air bleed at that rubber feel seal works. MY MAIN fault now it that with any attempt to jack up, it just kinda moves but never gets up. Worse, I can lift it up by hand (with pressure), then push back down - no fluid is leaking out though. Is it that u-cup as you showed?
Really enjoyed your jack repair! I have a Harbor Freight Hydraulic lift that has a significant drift!!! Is there an EZ way to stop the drift other than supporting it from below with a number of blocks??? There is no leaking of hydraulic fluid at all... Thanks
Enjoyed your video, i have a lift jack that needs a rebuild kit after seeing this was intimidated at first but watch video again and am willing to give it the old college try. I am also of the mind that i would spend the time to fix stuff then to junk it.
Great video! You got a first-rate deal on that jack. I'd love to find one of those big old service jacks in that condition!! Are you filling them with ATF or just using it as assembly lube? I've always used jack oil, but how necessary is it? Have I fallen into the trap of need jack oil so buy the expensive bottle, when ATF, or even backhoe hydraulic fluid, would suffice. Thanks!
I filled it with lightly used ATF mixed with some hydraulic fluid I had removed from my tractor while replacing hoses. Hydraulic fluid by itself from a tractor etc is generally too thick and will cause the jack to be sluggish in the cold. It will work just fine though. ATF is the right viscosity for all temps. Really the only reason ATF isn't used from the factory is it's more expensive than jack oil. ATF is overkill due to all the additives and performance standards it has to meet but that's generally what I have laying around.
Nice job 👍 Moe ! Jacks Are Pretty Straight Forward . I Agree Once You Work on Them. You Can Fix Most. Sorry Ginger Hurt Her Leg . That Was Nice You Trying to Make Her Feel Better.
Hmmm! Nice lesson! What did I learn? More than one moving part equals consider hiring an expert. I have an ancient jack in an ancient barn looking for a seasoned hydraulic pro to save me from otherwise wrecking it. Some consulation is the generations of handy persons that have passed on this project. Ooh so many projects, so little time for my limited ability to focus! What a world! What a world!

Excellent video👍
@@BernFricke I worked a hydraulic shop I Odessa Tex in the late 70s early 80s. Just the 2 of us did right at 300,000.00 a year repairing these old tools. Once the Chinese junk flooded the market no one paid to have good American made equipment repaired. Glad to see this channel up and running.
Exactly the kind of video I need right now .. and I don`t even have a broken jack.
Agreed!
I have a leaking craftsman two stage speed jack that I've been needing to fix for a few years so yes it is the perfect video.
Same here, just needed a few hints where to start
This is good to know info! I’m afraid to touch my jack , but can rebuild a 6 speed automatic with eyes closed😊
I don't even have a hydraulic jack but nothing beats a thorough rebuild instructional video. Didn't know floor jacks were just horizontal bottle jacks 😂
See that he went from hydraulic jack repair to dog medic without even skipping a beat.
Proof that this man can do almost anything! Great video Moe, thank you!
Hey Thanks.
Good old days when man could take care of himself and others and fix things
Im a retired auto mechanic and over the years I've done countless teardowns and assemblies, but after seeing this i know ill just buy a new jack if my old one quits working. Hey im 63 and i dont need the hassle, i want as much non-mechanic time i can get while im still around. But you know your stuff.
Words of a wise man, time is the most valuable thing we have.
Most new jacks are craaap! I’d rather rebuild an old timer. I mean you can always find an hour or two where there’s nothing to do, especially being retired.
@@billmellater the problem with that is most rebuild kits are also craap unless you find new old stock that wasn't made in China India etc. their rubber O-rings/seals are junk
Your older jack has a lot of life to give, when you buy a newer likely worse jack that easily fits your needs you can sell it cheap to someone who wants to fix it and will treasure it for years to come, this is a great service
65 here. Used to use ramps but the 94 Mercury Cougar I inherited hits the lower front end before the tires head up the ramp. I have old snap on jack that has been sitting under trees for over 10 years. I here the new ones are 1000.00. I bought a low profile pittsburg at 60.00 off for 100.00. I think it would have cost a lot more than that to repair the snap on. I only use a jack for oil changes once a year. I'm sure someone would really love to have the snap on for repair.
You are good at explaining things (teaching) so that even a simple minded person can “get it”. So many lack that skill!
Well ya can't say this guy doesn't know Jack. He most certainly does.
Great video and fixed my Jack! I want to let you know you did two things in the video. You taught us how to rebuild it and how and why the Jack works. 99% of people don’t care how it works, we only want it fixed. LOL
I’ve got a (nice at the time, Craftsman) Jack that I used to use in the late seventies when I did my own work on my cars. It hasn’t worked in ages, and I’ve been convinced it could be repaired easily enough! Thanks for sharing; everyone says “they’re cheap, just buy another one “, but I’m not that guy… fix it is my motto
There is way too much fixable stuff just thrown away, then replaced with cheaply made new junk
@@keljan11
and the landfills keep filling up&up . . .
I agree with that. If I can fix something, that's what I would rather do. For some reason, I didn't think to take my Jack's apart to see if I could repair them. Now I will.
Your vast knowledge is astounding! Is there anything you can’t fix? Great job and as always appreciate you sharing your knowledge.
Hey Thanks. If there is something I can't I hope to figure how.
@@sixtyfiveford master Yoda ,
There is no try just do.
I have a feeling that he can't fix stupid (in others.)
@@Guillotines_For_Globalists That's one of the easiest things to fix In fact he is fixing stupid through the cumulative effect of his vids. He is not only showing us how to fix / make stuff, he is showing how to approach solving problems and to think outside the box (which is EXATCLY how to "fix stupid"). Now, hopefully you are smart enough to stop spreading the "cant fix stupid" idea... cuz it is a remarkably...well ... stupid meme (I'm not saying your stupid, just that the idea is - cuz "stupid" is so ridiculously easy to fix, and happens to basically everyone on the planet as they grow / learn ... (Now I suspect I should BFI)
Nicely done!
I have a 30 year old HF cast-iron beast proly 80lb, still works fine. Holds a load fine. Sits out in the rain and snow so the star wheel is hard to turn. Bought in a box full of returned HF tools. I'm guessing the reason why it was returned is because only three of its wheels touch the ground. It has always worked just fine. Advantage is the same as a pine wood derby race car, less rolling resistance. LOL! No issues lifting my GMC K2500.
Thank you for the video, always more to learn.
The blue Lincoln jack at the beginning i worked for that company for many years. One oddities in the pump seals cylinder. Leather v-cup washers are used. Everything we tested leather was the only one that held up. Rubber plastic etc. Wipe the cylinder clean of oil on the back stroke. Leaving it dry for next stroke.
I rebuilt all my jacks, this video is a good brush-up on the procedures and is appreciated. The big RED you have is a copy (?) of an all-construction cast iron Blackhawk 3-ton 1945 vintage (mine) which I have and rebuilt, they used v-packing for the seals back then which I retained. It is a 2-speed, Fast upstroke until it senses a load then reverts to 3/4 inch up increments, with a 24-inch lift. It even has a key lock in the handle knob as a safety measure to prevent opening/closing the valve and a battery-powered front light to see in dark places wherever you roll the jack under, cool or what!! It is a heavy beast but a beautiful antique jack. Again thanks for the video.😎
Reducing the db at 4:58 what a legend. Thanks for not blowing my hear holes out and teaching me something new. Good video man
I like the fact that there are others who's garage is pretty messy but can still get shit done.
I also got a really nice commercial Hein Warner floor jack at a yard sale for $25. She works but leaks, will need to do the same re-build.
Thanks!
Thank you! I am a learner and i was afraid to take apart a car jack because i did not know what to expect, but after watching this video after few hours i fixed two car jacks in my uncle's workshop that have been laying around broken and unused for years!! Spending only 11$ !!!
That's awesome
How did you know what needed to be repaired?
@@timscott2329 it's all metal and rubber, so the rubber is the thing that falls apart. All i had to do is replace the seals. Some were clearly broken in pieces and some could still work but i replaced all because it's very cheap to do so. I discovered that some jacks have the main seal made in teflon: these require heat to be both put in place or removed.
From someone that has worked on many jacks, that was a very good description on how they work!!!
Master Class, Now to fix my 50 year old jack, It currently will not lift a car more than 200cm then drops to rest. Thanks for posting mate.
PERFECT! Solved my problem. My trolly jack all of a sudden would not lift very high and even then it would deflate upon its own weight. My jack is 30 years old and when buying the hydraulic oil I had a choice between AW-32 or AW-46 ("W-46 which is thicker and less likely to leak from an older machine") I drained the old oil and followed your video - 10/10 - Thanks!
Had no idea there were this many types of O-rings & seals inside a jack. Hope the pup heals up soon!
I'm calling it this is by far the best jack rebuild video ever👍👍👍 excellent channel!!! 😎
I’ve watched many and rebuilt a couple and I have to agree. 🔧👍
I work offshore in oil production. We use charcoal lighter fluid to clean parts, slowly switching to using it at home as well! Great vid, on showing how to repair/rebuild!!!
Interesting. I'm pretty sure charcoal lighter fluid is naptha. I know my favorite concrete degreaser has a lot of naptha. Never really thought about it as a parts cleaner but it makes sense.
@sixtyfiveford the lighter fluid with naptha you're thinking of is zippo lighter fluid great degreaser but evaporates quickly charcoal lighter fluid is closer to kerosene or lamp oil
Been using kerosene for years. Works awesome
I've noticed that super cheap lighter fluid smells like diesel fuel. It makes the food taste horrible. Don't know if it's actually diesel fuel or not. If it is, then wouldn't that destroy some seals? Or is diesel fuel only harmful to gasoline style gaskets?
I repaired an old BRADBURY jack of my fathers, probably 1950's. Had the seals custom made. Quite a simple but super robust, powerful jack. Works really well now.
If you have a shop press with a pressure gauge, then you can easily readjust the pressure relief valve under the orange cap. When I overhauled my 2.5T floor jack, I found loose casting sand inside, so I completely disassembled the jack to clean it all out. After reassembly, I put the jack in the press, extended the arm up to the press ram, then used the press to push down on it until the pressure release valve in the jack let go to get a pressure indication, being careful not to allow it to exceed 3 tons. Adjusting the valve, I was able to reset the check ball to release between 2.5 and 3 tons.
Great information, thank you.
I have a 4 ton Jack just like this that hadn’t lifted in years. Now I have a great idea how to tackle it ! Thank you
Great content as usual! I hope Ginger has a quick and full recovery 👍
Thanks friend for making us ones that never throw anything away glad we kept our stuff around to fix cheap someday. Btw ironically my Australian shepherds shoulder is also jacked up, been going on & off since this past August I even spent $360 on an x-ray that didn't show anything but eliminated some of the unknowns, I guess next step will be an MRI, he's my 8-year-old boy, (only child) so damn the cost!! ✌️
Yeah this has been going on since at least the beginning of summer. I'm assuming it's a torn muscle or something. Dogs just don't know how to let stuff heal though and take it easy. I thought about splinting it up so she just limped around and didn't use it but then likely she'd hurt the other leg.
I only watched this as I have a Jack that looks just like the Coats Nike with the exception of the wings for the castor wheels being pressed not cast and the handle has a quick release plunger not a pinch bolt.
I re-sealed the pump on mine and blasted and painted the whole thing as it was mostly missing all its paint, it also benefited from getting all the pivots out and
freed up so that they stay static in the frame and the arms rotate on the pin as they were turning in the frame when I got it. I will have to investigate mine as I think it might have the speed lift, from memory the valve body has the extra port, but it definitely doesn’t seem to work and it would be real handy if it did!
@@sixtyfiveford If the doggo doesn't have a bona fide injury but rather a strain or hyperextension kind of deal going on... you're going to have to just lock her up for a good couple of weeks to a month. And I mean so she cannot run or chase at all. That's about the only way to get things healed up because the dog is going to do what dogs (and KIDS!) do which is to keep right on going and that often leads to an injury never healing up or worse. What's worse? A permanent injury. BT & DT a few times over the decades. Including to myself as a teenager until I was forced to cease all athletic activity by my parents until I healed up and was cleared by the doc. Hey! I could still catch a football even with a cast on my arm?!? Best wishes!

What a great deal on that heavy duty jack. I fished a 2.5 or 3 ton, can't remember, jack outta the dumpster a while back. It's an older, made in japan orange jack in great shape except for a missing handle. I have the rebuild kit, just haven't taken time to do it yet. Thanks for all your useful, informative videos!
Cool information, thanks. I’ve kept my grandfather’s old jacks hoping to one day fix them.
Thank you so much! I’m old but never really learned how stuff works until recently… honestly never really cared until I became so broke (long story) I need to repair things myself!
Seriously thank you from an ignorant old man trying to get educated!
Never too late to learn!
Another helpful video. It has given me reason to repair both of NY broken floor hacks! Take care of that wonderful pup!
Where do you get rebuild kits for harbor freight 3 ton jacks thanks I’ve been wanting to learn how to rebuild my floor jacks for 35 years instead of throwing them away
Google your jack and you'll find rebuild kits
Ginger has been with you a long time. she starting to get a little older and she's so very active. that she needs a little muscle massage every now and then. she's such a great shop companion. this was a really comprehensive video on rebuilding floor jacks. you covered all bases another great video as always. thanks for all the great work you do.
My 6 year old 3.5 ton Napa jack failed on me last week. Glad I had the side by side blocked . No oil leaks so will look at the check valve components. Great video. Your explanation on hydraulics was perfect.
Excellent video, have a Lowes Kobalt 3T that pumps occasionally when it feels like it. Talked to two hydraulic shops and they said that they are throw away. It looks identical to your Craftsman 3T. Think I'll try taking it apart completely this time, last time just replaced the O-ring at the top of the canister and verified that the cup seal wasn't damaged. Think now one of the ball checks are sticking and/or dirty.
I have the Craftsman 2-ton. Its around 40 years old. It survived my brothers abuse and is still working fine.
I was at a friends house. His jack would not roll. When he stepped away, I oiled the wheels. Took a while to work, but was rolling by the time he came back.
Great video, you give solid hydraulic theory, then show how everything works! Then give great repair video!
Nice, thanks! I have an old jack in the garage, friend said it stopped going down. Haven't looked at it too close yet cause I didn't really know what I was up against. I think this will motivate me to go look at it
I worked for a shop in east Dallas that rebuilt auto mechanic tools of all kinds. If a tool truck sold a tool to a line teck at a dealership; we would rebuild that tool when it needed it. There were about 4 shops around Dallas that did the same thing - this was in the early 80's. Brought back a lot of memories; while watching your vid my imagination was smelling all the oil/grease smells I experienced. Working at this shop was a few years before Harbor Freight and their cheaper tools from china became popular. Line techs only bought CN, Ingersol'ran, or Snap'on back then. With the floor jacks, the dealer's mobile battery jump start equipment, and air tools - we were always busy. I got pretty good w/the 20 ton floor jacks. We had a test stand that went up into the 60/70 ton range. The test for the floor jacks was 24hours at the jack's maximum w/out any bleed down on the test stand. I had 2 of those floor jacks seal cup blow out while on the test stand as I was walking by them, talk about getting all shook up. Of all the jacks I rebuilt I only had one that couldnt be rebuilt. I rebuilt it 3 times and it always leaked down on the test stand. The boss even rebuilt it once; said w/his 30 years experience he's never had a jack that couldnt be rebuilt - no telling what that jack had been thru; if only that jack could talk. Thx for the vid. Brought back a bunch of memories
I have a small yard sale jack that needs seals. Great video! Thanks
I hope Ginger is quickly recovered. One of my 4 dogs turns 13 today. We got the word back from his $513 vet visit last week that the tumor on his belly is malignant and is scheduled for surgery on Dec 27. $900 more cost. Merry Christmas Jethro the Chihuahua, you will be biting ankles for a few more years! Get well Ginger!
MEMORIES WELL WORTH IT
Dang, I wish you the best. It'll be well worth it. Expensive but I wish human health care cost this little. I can't even imagine how much they charge to remove a tumor from a human.
@@sixtyfiveford Dogs are worth it. They provide unlimited love. Vet said we caught it early. Testing & X-rays show he has clear lungs and good heartbeat. I save money by doing my own repairs on stuff, so I have money for things like rescue dogs. A Chihuahua, a Yorkie mix, a Boxer mix and a Pittie mix all share our house with the two cats.
Get a 2nd opinion.
I love how you take us through a project with plain english and simple guidance! The check valve layout that you did was super helpful! I thank you for sharing! Then, at the end, when your furry relative had the hurt paw, you had me saying awwwww. Nice video!
Greetings: He can keep busy all week with the HarbourJunk stuff. Thx 4 the share.
Thanks for sharing! I have a jack that is acting up and another that i retired and just havent thrown away yet. I will be rebuilding them now. Thank you!
The love between two different beings is awesome to see. Symbiotic | Great content as well
Very cool.
Wish they still made quality jacks like that one.
Cheers
Excellent overview, sorry to see your pups in pain.
I fixed one of my jacks by refilling it with ATF stop leak in ~2008…it had a leak, lost almost all the oil, so I did that. It still works, now. I don't use it as much because the wheels are loose, but I can't throw it away because it works, and hasn't leaked or sank since my "repair"…from an open bottle I found in my garage.
It may not work for your jack, but it might be worth a try.
A product called AT-205 reseal actually works good to revive rubber & dried seals.
@@michaelbrinks8089 good tip Michael. Scotty Kilmer endorses this product. Don't know if its available here in Australia. We get most stuff I see in the States, Lucas etc. Regards Bruce
Ginger is so sweet. Hope she heals quickly and fully. ❤🐶
Thanks for sharing. Very interesting/educational vid!
Hey thanks
Thank You for this video. Several years back we bought a military jack of about that size to R&R the transfer case from the M925 6X6 we bought. It was a bit leaky but did the job, plus I have 2 HFT hydraulic tables to rebuild. Plus 3 bottle jacks that were my fathers. Now I know what measurements I need to fix all of these.
FUN!
I never realized, until watching this video, that these would lend themselves well to being turned into hydraulic presses compared to smaller bottle jacks. That T bar would be useful. I'm going to keep that in mind when I have to build a press later on.
Very true.
If you build one, I’d love to see a video of it. Good observation. 👍🏻
Make sure you test the jack in the mounting attitude you plan to use it. The check balls may not work properly if mounted vertically
Nice work on the jack and a killer deal.
Working at UTC I discovered a problem.
The hydraulic presses were built to run at 3000 psi. The plant manager wanted to speed up the presses so he had the pressure raised to 3500 psi so they could accept 9 inch billets instead of the 6 inch they were designed to push. .
The plant was built in 1951 and the owners were scrap dealers so all the equipment was second or fifth hand by the time they got it.
The maintenance men were OJT and no one was trained how to train them.
The lines were springing leaks all over. Every fitting was extruding the o rings through the gaps between the flanges.
I thought at fires it was the increased pressure. I turned down the pressure as an experiment.
The lines were still blowing out the o rings.
I checked and the stock of o rings were made from 70 durometer rubber used for air and water lines
I replaced them with 90 durometer o rings for hydraulics and stopped the problem of the o rings failing.
Sounds like a win right? With the high pressure o rings not acting as a blow out plug the presses ran with the 3500 psi oil pressure but the 10 ton cast iron platen on the 1600 ton Youngstown extrusion press cracked in the middle.
It took 3 months to get a new one made by Youngstown.
Solved one problem and made another.
Give Ginger a pat for me.
Grand Central! On State Street! I loved that place .. When I was a kid we hit the one with the round roof (arched front) .. Too fun .. Some turned into Fred Myer's .. Off to work on my dad's jacks :) .. he's got one of those biggies that've been down for the count for decades .. I need the brand and I'll order him the orings and u-seal ..
Very NICE training We have three foor jacks that have that disease of not holding the weight when extended !! I will have to remember this video when I get to it!!
Very well done video. I've been wanting to rebuild mine for years... It's so helpful to understand the function and guts before tearing into it. Much appreciated.
This is surprisingly complex. Good video. I was about to repair my two -- 2 ton jacks because I saw puddles of fluid. This is some good knowledge.
I must have 3 or 4 floor jacks hidden under work benches. ,, Guess it's time to buy a kit or two and put them back in service. Thanks for sharing your knowledge.
Some of the more common jacks you can buy a whole kit for around 25 bucks. That's not bad considering the cheapest 3ton jacks or well over 100 nowadays.
Those are Jack's for semi trucks, busses rv's etc. I worked at a heavy truck shop for 16 years these were awesome jacks
Awesome. I need to buy a semi now.
@@sixtyfiveford😂
I have and still use that same, beefy Japan made blue hammer finished Craftsman 2 1/2 ton jack. Also have a matching mint screw type differential jack (made in Taiwan). I hurt the Craftsman as it was low on oil and the internal screw was semi-dry making it stick. We always forced it loose with the handle. I disassembled, scrubbed, polished and lubed it completely about 4 years ago.
Thank you for making this.
Still got my bottle jack from teen wrenching days probably 40 years ago. Had to ponder that for a moment.
Very informative video.
I had a problem with handle kick on a small jack, almost never used. Hearing that the return valve is gravity activated led me to fixing it by turning the jack upside down to oil the valve-ball end then knocking around the master cylinder with a small hammer to get the ball moving. The jack now works flawlessly.
I didn't find this solution anywhere, but wisdom is power!
My guess is, that setting the jack aside in the case it is delivered in, where it is actually standing on its side is not helping things.
You are a Genius. Thank you for taking the time to film and post.
5:00 I make a wrench out of oak to remove a large nut, whenever I need a one time use wrench
I have been waiting for you to do this video. Picked a 3 ton General from the trash and need to rebuild it. Getting popcorn now...
Free jack is always a win
Yes I have done this many times to save money. The video on making the socket was great 👍
Glad you liked it
Great video !!! Most importantly is the trust that dog has in you !! No doubt you have been good to her !! I like the way she jumps up to let you ease her discomfort. Amazing Dog she is and not enough said for her owner !! Thanks again for the video on the hydraulics of a bottle jack and really how simple they are to rebuild.
Thanks 👍
Probably the best info video I’ve seen. Your pace is perfect, your explanations are great, and your camera work is outstanding! Thanks for your work putting this together. I’m sure many guys will benefit from this. Well done! ❤
Glad it was helpful!
Great demonstration on how hydraulic jacks work. Where do you get the diagrams? I have several non working dump pick jacks missing handles, wheels and the plate that pushes up the vehicle that I plan on piecing together to get at least one good one. The rest I have plans to refabricate into other tools. Adding another 👍. Hope Ginger heals soon.
Stay well, Joe Z
On my 3rd cattle dog. She had her 2 back knees done. Great video
I watched this but I am more intimidated than ever- I’ll buy a new jack. You’re way beyond my league 👍
I have 3 non working crap jacks.... I'll give this a shot.
Those Nike jacks usually lasts a life time of hard work!
Thanks Moe. I watch all of these hydraulic repairs that I can. If you own hydraulic jacks you WILL, some day, need to overhaul one. Tell Ginger that Tater Tot said WOOF !! That jack is not the only thing that has trouble staying up........ oops ! Did I say that out loud ?
I'll take Jack to the gentleman's club and see if anyone there can help Jack out.
Awesome video. I have inquired about having my Walker jack serviced and was told to just buy a new one. This isn't a Harbor Freight jack, Jack.
Those Walkers are great jacks. The catch 22 of living in America is we can't afford to have fellow Americans work for us. It's cheaper to buy new. I messed around with this for 3+ hours. At a shop rate these days of $180++++ and marked up parts prices, this could have easily set someone back $700-800 in repairs.
Great to know you can easily rebuild your jack. Mine works fine but this will come in handy one day.
Wonderful demonstration thanks
Great idea to show how floor jacks work like how you made your own socket to remove the part of the bottle jack
Hey Thanks.
@@sixtyfiveford you are welcome sixty five Ford
Great knowledge, great video - it's unlikely that 99% of us will ever strip a complex 30 tonne jack. Would you consider making a video of a standard, budget 3 tonne floor jack strip down, check and seal replacement? That would be really useful.
Craftsman used to sell a compact high lift 2 ton with the rapid extend. It was my favorite Jack until i used it under water and the high speed went away. Maybe it's time i tried opening it and seeing if it just needs a new ball in the high speed check. I thought it would be more complex so i never opened it. I probably broke it in 2009, still use it today
Appreciating a great tool and understanding its potential!
Another great video, thanks for sharing your vast knowledge. I hope Ginger gets well soon, she is such a ball of energy.
She would of she would just sit still. We were doing great this afternoon; no limping at all and then a squirrel.
Great video as always! Glad to see Ginger is enjoying her massages too! Thanks for sharing!
Awesome video on the inner working of hydraulic jacks. Hoping to figure out why my hardly used cherry picker only pumps a half stroke. I added fluid as it was low. Before adding fluid it wouldn’t pump up at all. After seeing this I think I will remove it and fill it with the cylinder laying down horizontally. Hopefully that works. You’re amazing, love your content. Thank you for sharing this
Air bubbles can be a pain. Sometimes laying the jack on it's side with the pump down(that's where it will pick up oil) will allow air bubbles to flow out into the reservoir
@@sixtyfiveford thank you I appreciate it, I Will try that.
You are amazing man, very talented in your ability to explain things with your pictorials and large scale visuals like the pipe with the pool table ball. Thank you.
Nice information. I have an old HF 2-1/2 ton long frame jack, that leaks oil.
It could be as simple as the o-ring in the gland nut. Problem is the hardest part of repairing a jack is removing that nut.
I bought a cheap floor jack around 25 years ago and it still works; I think because I bought a bottle of hydraulic fluid and topped off the fluid immediately when it was new. My brother claims his just failed in a MUCH shorter time. They don't like to ship them with lots of fluid, I guess, so you need to top up the hydrolic fluid in your new one if you want it to last. . . or you will end up doing something like this . . . much too early!
I like to take an air powered bottle jack and put them in there and use it that way just because it's faster,it still works really well if you have time for the modification.
Best teardown and repair video I've seen so far. My 2 ton engine hoist/lift stopped working. It required further and further tightening of the release valve for it to work. Now it feels like it goes mooshy inside. Like maybe the seat of the ball split open or something.
Can it be replaced?
Great video. I have always wondered how to repair jacks. Thanks
MM77 Approved 👍🏼👍🏼……………………………………………………………………Very good explaining how a bottle jack works. I felt like I was back in hydraulics class , I mainly remember the instructor used to say “ Flow makes it go”. He was retired US Navy sailor who was on carriers and worked on the catapults. That man had some STORIES !! LOL
That would be a neat job
Thanks Moe for sharing your knowledge on floor jacks and their repairs. The only thing is that I’m not sure if there’s an available kit to repair mine. But maybe I’ll do what you did and just try to match the seals from a kit.
The COATS NIKEE jacks as we spelled it at the shop were sold by both by Snapon and Coats FMC the makers of the tire machines. My dad & grand father bought a coats machine the bubble balancer new in 1967 it came as a package deal the jacks were sold separately. I think they paid a total of like $1,700 for the machine and balancer the jack was like another $200 bucks. If I am correct there was a bubble balancer for car tires and a larger one for light truck tires.
Wow, a battery-powered heat gun!
What a great time to be alive 👍🏽
Love the video! Hope your pups paw is healing up. I do have a few jacks some I'm not using because they Creep down when having weight on them. And most have age but not used like in a shop everyday. And idea or just a total seal replacement like in your video.
Hey thanks. Creeping down is either the release valve, the pressure holding check ball or the main piston u-cup seal.
Help, no sane person would put as much effort into this as I am. I keep reviewing this and other vids, but this is most educational. I finally understand that check valve ball, I was going to ask how to set it (most just say tighten and back off), but I think I get that (I had it al t he way down and that may have been preventing all fluid from entering, so nothing worked. My Craftsman is weird though, it's got like a sealed screw, covering the screw that holds the spring/ball. That seal (flat/square o-ring, not just o-ring) might be the culprit. I'm trying to rule everything out prior to complete disassembly. Air is entering somewhere as I KEEP successfully bleeding, but with any movement, air returns and another air bleed at that rubber feel seal works. MY MAIN fault now it that with any attempt to jack up, it just kinda moves but never gets up. Worse, I can lift it up by hand (with pressure), then push back down - no fluid is leaking out though. Is it that u-cup as you showed?
That’s one heck of a nice jack for 20 bucks. Even with the rebuild kit and counting a guys time you’re well ahead on that one.
I think I'll be very happy with it.
Love the dog; you really take great care of her; great video too !!!!
Really enjoyed your jack repair! I have a Harbor Freight Hydraulic lift that has a significant drift!!! Is there an EZ way to stop the drift other than supporting it from below with a number of blocks??? There is no leaking of hydraulic fluid at all... Thanks
Enjoyed your video, i have a lift jack that needs a rebuild kit after seeing this was intimidated at first but watch video again and am willing to give it the old college try. I am also of the mind that i would spend the time to fix stuff then to junk it.
Go for it!
you know jack!
feel better soon dear girl!
Thanks 🙏 for sharing this video sir. You have demonstrated very well the process of the repair.
Great video! You got a first-rate deal on that jack. I'd love to find one of those big old service jacks in that condition!!
Are you filling them with ATF or just using it as assembly lube? I've always used jack oil, but how necessary is it? Have I fallen into the trap of need jack oil so buy the expensive bottle, when ATF, or even backhoe hydraulic fluid, would suffice. Thanks!
I filled it with lightly used ATF mixed with some hydraulic fluid I had removed from my tractor while replacing hoses. Hydraulic fluid by itself from a tractor etc is generally too thick and will cause the jack to be sluggish in the cold. It will work just fine though. ATF is the right viscosity for all temps. Really the only reason ATF isn't used from the factory is it's more expensive than jack oil. ATF is overkill due to all the additives and performance standards it has to meet but that's generally what I have laying around.
Nice job 👍 Moe ! Jacks Are Pretty Straight Forward . I Agree Once You Work on Them. You Can Fix Most. Sorry Ginger Hurt Her Leg . That Was Nice You Trying to Make Her Feel Better.
I always think they're fun to work on. Thanks.
Hmmm! Nice lesson! What did I learn? More than one moving part equals consider hiring an expert. I have an ancient jack in an ancient barn looking for a seasoned hydraulic pro to save me from otherwise wrecking it. Some consulation is the generations of handy persons that have passed on this project. Ooh so many projects, so little time for my limited ability to focus! What a world! What a world!
