Hydro pump not spinning with transmission

Recommended Posts

I got a parts tractor yesterday because I needed a tranny. It's a 312-H, my problem is that when I push the tractor everything turns but the hydro pump is that bad or good? Plus on the side of the tractor where the pump is, it seemed like there is/was a leak should I pull the pump off ?

I assume the engine does not run and you don't plan to get it running. 

    If that is the case, the way I have tested hydros is to chain front of the parts tractor to a tree. Then drive the tranny with a long belt and another tractors PTO from the rear.

If the tranny will spin the tires in forward and reverse after the oil is hot, I consider it AOK.   If there is a leak, it may show up.
