drp198 0 #1 Posted February 24, 2017 (edited) 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 ?

Ed Kennell 38,716 #2 Posted February 25, 2017 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. Share this post Link to post Share on other sites
