I bought an old floor jack at auction a couple of years ago that would only lift about halfway up. It is a large one, maybe 3-4 ton at a guess. I left it outside for about a week earlier in the summer and I think it lost a seal because it stopped lifting at all. i am not sure if sitting out had anything to do with it or if it's a coincidence. It is very old and has no markings on it that I can see that tell who made it. Today I removed two plugs from the top, one had a cone and spring arrangement under it. I also removed the control unit form the top of the case and drained all of the old oil I could get to come out. I put some new jack oil in it but it still would not lift. Is it practical to try to repair a jack that is so old that it can't be identified or should I just get a new one? I like how big and solid this jack is compared to the newer ones I have had and i used it a lot. Any advice will be much appreciated. I can get a photo tomorrow if that would help.
