Wondering if anyone has found a good source for a seal kit to rebuild the gerotor and gear pump section of the 70271875 and 70268882 hydraulic pumps?

If not would there be any interest if I can source a manufacturer to build them?

Ok, I dont have a timeline yet. Currently putting a used pump in our 7030 to get by, at the end of the day its still a 45 year old pump with 45 year old seals. At this point I am working with a machine shop and a 3D printing prototype company to come up with a solution.

Eaton bought that pump design from cessna. Ive got one the only difference i can find is the case drain is a hole in the pump face back instead of external. I dont know if they still make them or the part number right now. Might be an avenue to keep an ohterwise good tractor out of the scrap yard. If there is any interest i can post the part #

I'd take any and all information you have on an Eaton kit. My local Fleetpride hydraulic shop said he had exhausted all his options with Eaton. Told him part numbers were good but had been obsoleted years ago. He was thinking a 26 series kit would work but its a different size as the Allis is a 29013RAD pump.
