8030 power steering motor

leaking out the top shaft? You are capable of repair. Simple seal replacement done without taking motor apart,just the top retainer. Biggest challenge is getting it out of there to work on.

Had one that leaked, took to IH guy, he said he could fix it, got it back and it never steered the same, turned hard.

Yeah, make sure you put it together correctly.  My neighbor had a hyd shop rebuild his and when they couldn't get it to stop leaking, he called a salvage yard and bought a used one.  My brother is pretty good at hydraulic stuff so we bought a seal kit and tried it.  Not that many pieces in the rebuild kit.  I thought we'd have to replace the bearing, too.  But an Allis dealer said they had the bearing kit on the shelf but had never needed to replace them, usually just the seals.  Inside the steering motor there is a cylindrical piece with several ports and he put it together turned 180 degs from what it was supposed to be.  When we started the engine, it immediately turned the front wheels all the way in one direction.  Thought maybe we had hooked the hoses up wrong, so we checked another tractor, they were in the right locations.  He took it apart again and the only thing that could have been put together wrong was that one part.  So he turned that cylinder around and we tried it again (with our fingers crossed).  You'd think that with the amount of tractors that use similar steering motors that there would be companies in the business of rebuilding them or that Eaton/etc would have new ones available at a reasonable cost, but they don't unfortunately.
