I opened it up very carefully with a sawsall (since I don't have access to a lathe) and disassembled everything, got the seal sizes, and ordered the new seals from hercules.com, cleaned everything up, welded it back up and pressure tested it with my air compressor and painted it and it worked great. I'm just wondering if anyone has the sizes of the seals in this unit so I can price them out before cutting mine open, at this point I have nothing to lose, if I ruin it I would just end up buying a new one anyway. If nobody has any info to offer other than buying new, or taking it to a shop to have it rebuilt, I will go it alone and post back my hopefully favorable results.

sorner the rod and piston do not have seals they are o-rings and you should be able to go to an auto store and just match the old ones with new. I've done at least 4 cub power steering cylinders in the past and they are pretty straight forward. I think I would find a local machine shop and have them cut the weld off. Sawzall is pretty primitive and I would think a much higher chance of failure.
