How I Repaired A Hydraulic Jack.

/ @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!

Brilliant idea using a vice to loosen the large top nut. Must remember that trick.

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!

[@jeffreykbevins7116]

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 . 🤗👍💫

[@SuperKranf]

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.

[@JerryDoe]

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.

[@AJRestoration]

Oh wow, I wish I knew this before. Thank you, Jerry!

[@user-du7pe6pm7d]

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

[@JerryDoe]

@@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)

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 .

[@ytlas3]

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.

[@rogerclark9285]

Is that seller still in business and do you have a name for him?

[@ytlas3]

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.

A great instructional video. The only thing you didn't do is find the original handle with the proper tip to open and close the jack valve and check to see if the extension on the top of the jack was stuck since it was acidentally left in the back of the pickup in a rain storm for about 2 weeks. Great job.

[@skeetermcswagger0U812]

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.

Hi, nice work ,you can use air pressured hot-water to clean the parts . Hydraulic oil as 32 VG or ATF fluid works

[@user-du7pe6pm7d]

yu would never want to use water on mechanical moving parts from inside - yu could use vinegar - it cleans rust very well -- but would have to clean it off well with gas anyway - water is kryptonite to metal - especially if it moves -

@@tandemwings4733 - huh - after many dozen times with different thinks - I have found gas to clean the best - with a part cleaning brush if applicable - then diesel to oil - but to each their own ! - water is not good for metal - nor can air get all water out before rust starts - it would take many many minutes to blow all the water out to the point of not a good thing -

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.

[@rottiejakeluke]

Great to watch this video.a couple of questions: how can I know what rings are needed, is there a way to order a kit? How can I tell what kit is needed/ are kits sold by what the tonnage of the jack is? I have 10 ton bottle jack that can operate with the manual lever, but will not operate with the air assist. Do you have any thoughts as to what me be the problem? Do you have any videos showing this type of repair? Thank you.

[@AJRestoration]

I have a O-ring kit that had the required sizes, The main shaft seal should be available at most hydraulic specialist companies. If the jack has a readable model number you should be able to find parts on amazon or ebay. I have a local company that specializes in parts for hydraulics, so I usually just take the jack to them and they can custom make parts if needed. I have not worked on a air assist jack before unfortunately, it could be a blocked passage. Best is to figure out how to disassemble the jack without damaging it, and clean the passages.

[@rottiejakeluke]

@@AJRestoration thank you for the reply. I may try to take it apart and see if there’s something I can see.

[@garymucher4082]

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...

[@AJRestoration]

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.

[@glenadolph]

Check with Lazzars for parts and seals.
