Craftsman Floor jack rebuild model 214.50145

[R1Rider]

I need help, my jack stopped working so I took it apart to get new seals and o'rings and found out that it was more than likely just low on oil. Its very hard to find info on these jacks! Mine is model 214.50145, black and yellow, I think its 3.5 ton? Probably bought it back in 1997? I found rebuild kits but not doing well with instructions.

here are a couple links that were sent to me. the very last picture in the first PDF is close to mine but not exact.

Google takes it to https://www.hcrcnow.com/shop/seal-kits/product/4325

the part crosses to this model hydraulics. Whether that is correct or not ask Google and the other people who posted.

Last weekend I gave it some thought. I did some digging into part numbers, replacement part numbers, manufacturers, and I made some phone calls. No one wants to rebuild power units made in China. However, with a lot of detective work I managed to find a seal kit for my power unit that includes all of the o-ring seals that typically go bad. Here are the part numbers:

Original power unit part number: 5954 (currently $173.49 from Sears)
Replacement power unit part number: G59305-0001 (manufactured by Shinn Fu Company of America, Inc. (SFA), http://www.shinnfuamerica.com/, current price $131.27)
Seal kit for G59305-0001: G59510-0000 ($11.55 plus shipping from SFA)

I found the seal kit part number and an assembly diagram for the power unit by looking in the owner's manual for another jack that uses the same G59305-0001 power unit, the Omega MagicLift™ Hydraulic Service Jack Model 25030. You can find the manual on the SFA web site with a little searching.
