Walker floor jack

I recently purchased a Walker 10 ton floor jack. It needs rebuilt and I bought it that way. There are several places online to buy parts. Is there one that is better? Any tips on rebuilding one of these jacks? Thanks in advance. Mike
 
Just thought I'd throw this out there. I have a 2 1/2 ton cheapie, might be Northern Hydraulic.

Anyhooo, it quit working. I opened the lower valve almost all the way and then raised and lowered the jack by hand several times. Pushed it down as fast as I could. It must have flushed some type of crud out of a valve because the jack works now.
 
The most common fail is the piston cup. If it won't jack up a load or creeps down fairly quickly, it is most likely the cup.

Easy fix if that's all that's wrong. Just unhook the springs, get the ram loose from the jack body, remove the big gland nut, pull out the ram.

If the seal is bad it will be obvious, usually split, or the cup blown out. If it crumbled, flush as much out as possible. If you do any more disassembly, watch where the balls, springs, pistons come from, and that they go back exactly as they came out.

That is a special urethane cup. You must go back with the exact same material and size. Standard hydraulic cups will not work!

You can buy the cup at any good oring/seal supply.
 
Walker made 2 different 10 ton floor jacks. 1 had ram come out center of jack and other the ram stayed stationary and outer part of cylinder moved out.

I have an old 767 Walker that I lost some parts for. Hard to get some stuff.
