hydraulic lift cylinder repair

[mark64 0]

I removed the lift cylinder from my B112 today since it has been leaking more and more oil lately. Oil seems to be dripping out of the ram side of the cylinder. Does anybody know are new seals, or rebuild kits still available? Mark

New O rings may be all you need. Kirk did a good post on rebuilding the whole lift system, not sure where it got stored at

Thanks for the link to the rebuild. I took mine apart today and didn't see a o-ring for the ram shaft seal. I would guess that's why it leaks out the end around the shaft. There is a brass bushing and what looks like a nylon seal also on the end cap that look o.k. I hope a set of new seals will do the trick. Does anybody have the simplicity parts drawing of the cylinder assembly? I would like to have a picture to look at to make sure I get it all put back together correctly. Mark
