Hi Guys. Great website! I've already gotten some helpful info on here by looking over other posts... I have an old Gehl 2500 and left side drive motor stopped working. Hydraulic oil level was good... no leaks. I checked hydraulic pressure and charge pressure on left side pump/motor - both read 0. I finally pulled the hydrostatic unit and found that the pin that attaches the splined drive shaft to the pump input drive was broken... two pieces of it found, but I'm not sure where the rest went (maybe just ground up?). The input shaft seal appears to be okay... My question is, it was a pain to get the hydrostatic unit out of the skid steer... At this point, should I just buy a new drive pin and put it back together, or should I open up the pump/motor transmission unit to see what shape the internals are in? It's the U Type pump/motor combination unit... Not sure if I would need to get all new seals, etc if I pulled it apart. I don't mind doing some extra work now to save me from having to do it all again later, but I don't want to mess it up if it's not broken... Any thoughts or ideas? Thanks, Deke
