Pump went in yesterday, it's a different tractor now. all better. The Ebay unit is identical to the OEM, no issues whatsoever swapping it out. The pump has a rubber spider that meshes with the drive gear, so 3 hoses, 4 bolts and it's out.

One more thing- There is a grease nipple on the ft cover that holds the bearings for the pump drive. Don't forget to lube the bearings periodically. There is a 4 mm hex plug below the nipple. remove it and pump grease until it comes out the hole for the nipple.

The Ft seal on the pump was soaking wet, as suspected. I also suspect there was leakage between the two pumps, as the power steering improved quite a bit, and lost a lot of the funky noises it used to make while turning the wheel. The old pump looks rebuildable, or at least disassemble-able, hard to tell where to find parts. I'll pull it apart more out of curiosity then anything, maybe see something to better understand the failure mode. If I can manage to rehab it, it would be nice to have a spare, given what things now cost out of India...

Seals and bearings part number are universal should be able to get at any seal and bearing outlet if not at a hydraulic rebuild shop

yeah, it's going to be a winter project to see if I can refresh it.
