I have a JD 430 with #35 loader. Has seen lots of loder use over time and seems like the original tractor pump is loosing some pressure, but works fine for 3 point. Thinking of putting a front mount pump on it as was used on a lot of Fords and fergusons with loaders.. I willhave a separate system for loader. Years ago I bought a hub to fit on the front of the crankcase pulley for tractor for another project. The hub was typical as used at the time, 1" shaft with 10 splines. I can't seem to find a shaft to fit this hub, they seem to be mostly 15 tooth. Anyone have one off of an old application of able to suggest where to find one?
