My floor jack does'nt work correctly. I pump a lot for it to move up. tried adding hyd. fluid but it seems full. any help would be appreciated.

Make sure the valve that lowers the jack is working properly.

sometimes they get air in them and you have to open the valve as if letting it down, and pump it several times. After that tighten the valve back up and try it. I have TWO jacks that are not working now. I have one that is the type that goes up on the first stroke and a regular one. To order a new "hydralic" is $124 when I only gave $85 for it to start with. I've trashed both of them and went to local store during a sale and bought a nice one for $48. These things are getting like most other stuff. Cheaper to throw it away and buy a new one than to buy the parts to fix yours. note: one of these jacks is just over a year old. I tried Several places to get it fixed or buy parts to fix them....none around in my part of the woods even touches them and my last hope to get some repair seals went up in smoke! Most of them are junk from China.

James B,

There is a ball check and spring that allows the piston to pull fluid from the reservoir into the pump. On the pump stroke, if this ball isn't seated in its seat, some of the oil will return to the reservoir and the jack will only get a small amount which makes it raise slowly.

I don't know your specific jack, but the procedure is to pull the piston assembly apart, clean any junk out of the tapered seat, and using a brass drift, give the ball a good smack so as to help it form a 'perfect seat' and seal 100%.

It's hard to explain, and it could be as simple as a tiny piece of crap in the seat, but this is probably where the problem lies.

Make sure there is a little vent hole in fill cap too. Good luck.

Just to add to what Stuart told you he knows about things he has helped me ,,,, I have a Walker floor jack i have for 25 years are more got to where it wouldnt lift and i got a lincoln seal kit and put it in been working good for years (A spanner) sure helps on the nut didn't have one ...even if yours is not leaking i thought i would pass this along and have good jack stands !! after living over one fallin on me i think of that ever time i get under one .

Say Daddy, where did you get the "lincolin seal kit" that you mentioned??? I have a nice small Sears floor jack that I have had for almost 40 years. I like it because it is compact and well made. It started leaking REAL bad, like pumped oil out all over the floor. I found that the seal had worked out of the groove on the piston and was folded over inside. I couldn't find parts for it anywhere, I looked for weeks. This supprised me because Sears used to keep parts for their items going back almost to the begining of time. I have gotten parts for saws that were 50 years old before.

bowtiedaddy-- I'm with Denny above. Where can Lincoln Seals be found? A number? I currently have one that is beginning to leak a little and one that just plain needs help. Denny, I agree with you. I recently got parts for a belt sander that I've had since 1973 from Sears. The sad think is the local sears that had a "repair/parts" place closed it and moved it 30 miles up the road and the service now sucks! How about bowtiedaddy, can you help us?

While looking for an online parts source ( which I didn't find ), I found this neat little tidbit. http://www.hyjacks.com/H2.HTM

Ok guys,

I just went through this with my 25 year old sears floor jack. It is a quality unit that was made in Japan.

I took it all apart to check for the leak. The ball and spring valve were in good shape. If they are not, you can get a new ball from a bearing store.

The main shaft seal on my jack was cracked and was leaking internally.

This is what I did, I went to a hydralic shop to get a new seal. They told me the seal was not available and that I might as well throw the jack away. I am not a hydralics specialist, but I now one thing and that is jacks are made around seal availability not the the other way around. The jack manufacture does not make pistons and cylinders and then see if they can find a seal.

So I found a larger hydralics shop. I called them and they said they had it so I traveled the 40 miles round trip to get the seal. The box on the shelf was empty. They ordered another one and I had it in a few days.

The long and short of it is I had my jack repaired for $10. It took awhile to get the right seal, but I still have my good Sears jack.

The seal turned out to be metric, if you have an American made jack the seal will most likely be imperial dimensions.

Take the cylinder and the piston to the hydralic shop and they can match up a seal that will get your jack back under your truck doing the job it was made to do.

40 miles!!! There should be plenty of hydraulic places around you closer than that!!

There are, but the ones in San Bernardino did not have the inventory. If the first one I went to really wanted to do business, they would have ordered me one, instead of telling be to throw away my jack and by a new one. This was a mom and pop shop that is small, I would think they would want all of the business they could get.

I work for a construction company and our equipment machanic does not buy hydralic parts in San Bernardino; must be a reason. The reason is there isn't much in the way of industrial suppliers here. You need to go where the truckers or tractor companys are.

You should have a Hose-Man nearby. If not, I.D. Industries is about 40 mile from San Berdoo in the fine city of Chino ( Or is that Ontario??)
