/ @ajrestoration So a while ago I got this "Bottle Jack" and two other ones at the recycling yard. I did a restoration on one of them and in my boredom, I decided to make a kind of a how-to video of me repairing this one.
The third bottle jack is unfortunately not fixable since it has been welded shut.
Anyways I hope you enjoy the video.
If you have any suggestions for improvement, or compliments share them below!

Thanks!
Thank you Chris buddy, I really appreciate it!

This is useless how can you make video with silence 😢
@@AJRestoration⁸
You got it 😄
No ego driven drivel, no stupid music......just the sounds of tools against surfaces. Outstanding. I’m going to fix mine. Thanks. Dave in Omaha
Without that stuff then there no video
I think this might be the best repair video I've ever seen, including pre internet era.
Thank you very much!
Brilliant idea using a vice to loosen the large top nut. Must remember that trick.
Works a charm!
Gives more leverage too
That's what I call a good teacher, no words needed
Yes, that for us visual learners, it's the best for me too.😃
Love the quite ,no annoying music thank you
My pleasure!
You're right! Stupid, annoying music has ruined many videos.I don't understand why people think that they just have to put music on a video.
Me too these type of videos with just the sounds of the process are the most captivating, btw do you have to strip it down this far to repair it?
With that 2 vices technique for opening up the big nut you just earned yourself my respect, a like and my subscription. Congratulations Sir
I'd use that monkey wrench hanging on the tool board
I have used a long handled pipe wrench or a big assed Crescent wrench.
Great little video, no excessive talking no daft music. Just good information. Well done. Now time to go fix my car jack lol
Glad you enjoyed it, and good luck!
Tip: you can replace hydraulic oil using mineral or synthetic 15w40 !
They have the same specifications and are less aggressive on the seals. I'm an engineer in hydraulics and we often replace hydraulic oil with 15w40 because it is less harmful to nature.
Oh wow, I wish I knew this before. Thank you, Jerry!
well -- depending on how much one is used - hydro oil has much more antishear and antifoaming agents - and would flow much easier it is said - and why would not a good 30 weight oil be as good if using oil - - a small pump does not need a flow rate additive - nor does it need a more expensive oil - if lazy people would change the oil more often - they could use anything - diesel fuel will even work - if it had additives - it could last forever - just a thought - they were selling replacement oil at harbor freight for a dollar - now Im sure it is 2 dollars -- ahahahahaha - i have a lot of old jacks - 50 tons even - did not know hydro oil was worse than the others for nature - must be some of the additives - cause oil is oil - and most studies on syns have not had enough studies - only that they last longer so they are better - we use less over time - oil company's are the only ones really doing the studies - and they are of course all LIARS -- ahahahaha --- paying trillions to cover up their facts and mistakes - even plastics - beings they are made from petroleum are said to cause cancer - hemp is said to be the best oil on the market - and with additives - they too can last years even --- the oil company's have paid tons to keep it off the market - even though it causes no harm to the environment --- but anyway -- ahahahahaha
@@user-du7pe6pm7d foaming is not an issue as hydraulic tanks are pressurized before feeding the hydraulic pumps, antishear also isn't an issue especially with synthetic oil because hydraulic pumps use butterfly valves to generate pressure and they are made from brass, hydraulic cylinders use seals they never touch metal to metal.
We actually found that replacing hydraulic oil with 15w40 was much softer on the insides of the hydraulic hoses, they often started to peel from the inside as the hydraulic oil was eating them away.
Nonetheless we switched to Castrol biobar duo environmental rules in many countries (I do maintenance for marine excavators the BA1100 in particular but also a liebherr 995 and the liebherr 994 is now replaced with an Hitachi)
Will 15 w40 or mineral oil work on a snow plow ?
@@miman-ck9jv for hydraulics ? yes
perfect video, no mindless talk, only explicit visual explanation, and I'm going to give my bottle jack a try at restoring it. Bought an 8 ton for 8$. It has no oil and I have nothing to lose, but some time. Thank you for taking the time to explain the process so clearly.
It's amazing, I repaired my 16 tonne jack to watch your video, now it is perfectly working. Thanks buddy 😁
I really appreciate the closeness of the camera. I can actually see what your doing. Thank-you. I also appreciate you getting right on subject, meaning I didn't have to listen to a long speech about safety glasses, shoes, gloves, etc.(I know all that stuff)

Just done this to my motorcycle lift jack. The piston rod had rusted and rust had got in and polluted the oil. I thought the seal might be gone, but once cleaned and refilled with new hydraulic oil it was fine. Wish I'd watched your video first!
Thanks for the video, I have an old big hydraulic jack, that my dad bought numerous years before I was born and I just turned 59 a couple of weeks ago and it needs to be fixed . So after watching you rebuild this one, I am going to try to fix my old jack, just mainly because it was my dad's and it being that old . I have 4 more newer jacks, one of them is only about 4 years old and the other 3 are about 20 years old .
🤗👍💫
how did it go?
THE BEST VIDEO EVER ON DISASSEMBLE AND FIXING AND MENTAINANCE OF CAN HYDROLIC JACK!! THANK YOU SO SO MUCH!!
Thanks for watching!
Well done, it was as if I was watching myself rebuild it; I have never done it and have one waiting out in the shop. Thank you.
Very outstanding work.thanks.👍
Great job. Might try this out on one of my old jacks. Thanks for sharing.
Never thought of the up side down vise trick , that’s what I call “ thinking out of the box “ .
I enjoyed watching the video.interesting n such precise workmanship.that’s how ide do it if I knew .rebuild the entire thing n clean it etc.great job.
Excellent video ,now i am able to repair my all jacks in my workshop.
That is great to know! Thank you very much!
Thanks for the great close up video shots! Tim in northern TN
I have at 15-20 hydraulic jacks that need that done to them. Good information. Thank you
Had one of the best oldest hydraulic bottle jacks probably there ever was & I can't begin to count the number big Tractor tired & truck tires it lifted After I know 35 yrs probably it started leaking around the seal very little paint was left on it & at the time I just wanted to go buy a new one for my Dad & we turned nthe old one into a door stop After a half dozen uses of the new bottle jack I regretted ever buying it but Computers were just getting started & I didn't know about researching for parts then .
EXCELLENT. I love the idea of using a loose bench vice for the large nut on top. I definitely will add that little trick to my "mental tool-box" !!! Very good demonstration ! When you went back and bled the filler hole of air, THAT'S what I haven't done! I subbed.
Bill, from Tn. 🇺🇸
very interesting! I learn new things all the time from you.
Glad to hear it!
Thank you, much appreciated! I’ve got a leaky hydraulic jack need to be repaired.
Great video with full detail. Thank you. What I'd like to know is where can someone get a O-ring kit for bottle jacks?
Nice tutorial. Thank you.
Very nice restoration. Thanks
Thank you too!
Interesting. Our late 60's vintage Sears Craftsman 1.5T floor jack (Made in Japan) has a thick rubber bushing near the base of the main shaft. It got destroyed years ago when my dad loaned the floor jack to a neighbor who tried to lift one side of his Kenworth tractor trailer. About ten years ago I managed to find a seller in Belmont Shores , CA who sold repair kits for various types of hydraulic jacks. I guess the moral of my story is, if you treasure your tools and equipment, don't loan them out because people won't respect them and destroy them, or they will and try to keep them.
Is that seller still in business and do you have a name for him?
It's been about ten years since I ordered the kit from him. I remember his business was at his home in Belmont Shores, CA. I remember his location because it took about ten working days to get the parts to me, just 12 miles away.
Nicely done.
if you go to a hard ware store make sure you buy the correct o rings they make metric and standard and don't over fill the oil great video
Excellent video and a nice change to leave the jack in its current external condition! Great work as always, dude! 🍻🤘💜
Thanks Andy! It is a little refreshing to see something in its current state that works a charm. 👍
Good to see you got the most mileage out of that rag
Very nice and straight forward tutor,
Great Job 👍!!
Very interesting, I never knew and I always wondered so I appreciate for Sharing with us👌👍
Ok that's cool
Great work as always
Thanks again!
Thanks for the rebuild
Thanks, helped me rebuild my Harry Moss hydraulic jack. Good editing makes it clear to follow.
Glad it helped buddy! Thank you for the feedback!
I see there was oil on top of the piston cup when you disassembled the ram, why did you not replace the piston seal? That looked like it was the problem!
Very good Job 👍
A very good understandable video. Thank you. God bless
thank you so very i never knew how to before now know how fix a floor jack now.🤔
Nice repair, AJ! 🔧
Thanks! 👍
Where do you find the O rings and seals ? They are not a common item in hardware stores. I really want to know
Nice content very inspiring and motivational have fun in the Philippines
Goeie werk! Baie dankie.
My plesier!
Brilliant, thank you.
please say about the availability of o rings and valves
nice tutorial.for overahuling jack
The plunger that we push up and down to raise the jack, I have leak from it and the seal is not an o ring but a wider thicker clear/yellowish plastic thing. Do you know from where I can get it.
Did you tighten the plunger sleeve off camera? Does the ram have screw extender?
great job
Wow great job 👏👏
Thank you! 😊
Ive got a ten ton jack ,I'll have a go at that now ,cheers pal for the vid
Good luck with the jack! I hope this helped.
@ajrestorations can it work without the rubber stopper for the oil fill mine is lost and I don't know if that's why it wont work
Great job
Thanks for teaching.
Nice work!
Thanks!
Big like for nice job 👍👍👍👍
Ótimas idéias parabéns
Did you change the seal on the main piston?. It looked a little flat to me. If a replacement isnt readily available maybe a little tread tape on the inside channel would give it more bulk and reduce oil blow-by.
This is helpful, thank you so much!
Nice vid.
Got to be honest though, it looked like it was just low on oil.
Maybe it would have kept leaking over time but who knows.
Interesting to see how they come apart.
The main seal was leaking a little, a quick fix would be to add oil, but I wanted to see what it looks like inside haha
Where.iwillget, jack, spare
The real tricky part is rebuilding the Jack handle.😄
Well now I know what the inside of a jack looks like I won't have to take it apart, I'll just add oil if it leaks a little. =)
Great pictorial but these things are so cheap nowadays it’s not worth the time to do this.
What was the sizes of those o rings that was used ? Thanks for the video 🙏
I have no idea actually.
J'ai ce problème sur 2 crics hydrauliques, je vais essayer votre méthode. merci
Thanks just what i was looking for
It's probably just slow and oil put some stop leak in there too it's good for the rubber seals
Nice repair...
I have a small collection of the older Jack's from the 70,s. You can't beat the old Walker Jack's and also an old sears jack all made in USA. I personally do not trust the made in China Jack's for they are poorly made. So don't discard Grandpa's old jack lol. Thank you for sharing this video 👍
I am glad you liked the video, I agree, I also don't really trust most things that comes from china, especially if its something that can kill you.
Congratulations.. regards from Athens Greece..
I see where the O rings came from but there were two special seals, one at the bottom of the body cylinder and one on the piston. Were they replaced? Where did you get them?
Este video merece mas de un LIKE.
You saved me money, thank you.❤️❤️❤️🙏🏽
Glad it helped!
Hi. Where did you buy this box of O rings?
The new maintenance standard for out of warranty Harbor Freight jacks. :}
My sears 6 ton bottle jack works but it leaks oil from the relief screw ( valve )…any way to fix it ??? Some kind of a seal that’s wore out ….there is no o ring just some kind of sleeve seal…thank you….
When you got the spares to do the work it can b done
Nice job 👍
Thank you! Cheers!
Parabéns.
De forma simples e prática executou o serviço, e ainda me encorajou a consertar o meu.

Good teaching I have learnt
wow. nice job!
Thanks for the visit
I have two of those mobi jacks. Was thinking of sending them to mobi jack to get them repaired
ahahahahaha -- get your money ready - they will tell yu about replacing all the old worn out parts that dont work anymore -- ahahahahaha - just buy new ones for close to the same money on line -- ahahahaha
That jack was jacked up but it is in working order for you fixed it yeah buddy 😎
You got that right!
@@AJRestoration yeah buddy 😎 . some of the people would say Chuck the one that is broken and buy a new one . You on other hand take a broken one of those and fix it saving the money 💵 to use for other stuff
I hate throwing things in the trash if it could be fixed or restored. That is why the metal recycling yard is my playground haha
Palit po ba lalat ng rubber at ano ang sira bossing
Pwede Po ba ilagay ung use oil Dina Po ba tanggalin ung luma
Well done an thanks for teaching this old one something new an useful yakoke
Glad you enjoyed it
Excellent video
Thank you very much!
I watched you disassemble this jack and replace the "O" rings along the way. And it seemed to fix the problem. However, do you actually know which "O" ring caused the problem? I ask because I got a floor jack that won't pump up and I can't find any repair kit of "O" rings for it since it is so old. I've already totally refurbished the entire jack and powder coated the parts that are used for the lifting operation. But the jack itself was only rattle can painted as to not melt the "O" rings inside when curing the power coat paint. . So I have to measure and find the individual rings to try and fix it. Just wondering if you knew which ring was the actual culprit...
Sometimes fitting a O'Ring that fits tight but is the wrong size will work, as long as it seals and does not pinch. In my case it was the lack of oil and the presence of air in the system.
Check with Lazzars for parts and seals.
What about using ATF instead of hydraulic oil? It has a strong dispersant package, as well as high pressure additives?
When I did some research on google ATF fluid was the alternative for hydraulic oil.
I've got my bottle jack in the vise but I cannot seem to crack open the top. any tips or tricks for that?
Just don't use heat, in this case leverage is your friend. I used a vice to grip it and used a pipe in between the jaws for leverage.
Sir saan maka bili ng pisa at oring sa sirang jack at anong klasing ang ilalagay
Where would you get a rebuild kit
It all depends on the brand and where you are located.
Gostei muito parabéns muito bom
Cool video.
Ngayon alam ko na. God Bless boy
Nice. Thanks for your time........
Bien instructivo excelente gracias
If a hydraulic jack will work without without oil in it will more than likely work with oil in it.
99.9% of people would have just filled it with oil and gotten it to operate and been fine with a little seepage here and there.
If I find a hydraulic Jack like this that will still operate I usually drain all the oil out and replace it with ATF and about a tbl spoon of Sea Foam and Marvel Mystery Oil. Usually any leaks that exist go away shortly after several uses.
It was interesting to see how it comes apart but I couldn't imagine you could find the seals for even if it needed them.
