Hi all, I just pulled my pump because I suddenly lost hydraulics and found the drive was the cause. Looking in my manuals I see that my drive doesn't match anything shown. My pump has a splined input shaft that slides into my now stripped hex drive coupler. Anybody know if this is a correct drive? Anybody have a drawing? My coupler setup didn't have a spring, but I'm thinking it should.

Sounds like the pump was chaged over at some point, the originals had a shaft with a woodruff key and it fit into an adapter that went on the pto pulley hub. You may to get a machine shop to make you a new part.I have drawings but I don't think they will do you any good. Let me know.

Hi Woodsman, I did verify it's a custom setup. Luckily the splined coupler had the company name "Hub City" stamped on it. I still have to modify it, but I'm gettin it done. Thanks.

Where was your pump mounted?

Hi Woodsman, My pump is front mounted just like the manual shows. Just the coupling is different. It has a splined shaft on the pump, a coupler that's splined inside and hex outside, and the intermediate piece has two posts that slip inside holes in an aluminum piece on the crank hub.
