Okay, I managed to get a used coupling assembly for my front hydraulic pump. Its a double roller chain set up, whereas the old one was the flexible spring shaft. I got it put on and aligned, and connected everything up. Started the engine, and it works like a charm, as long as I'm sitting still. If I'm going forward, the pump starts to squeal, like its binding. If I turn, it gets worse. The loader continues to work, but the squeal makes me think the pump is going to fail.
I pulled everything apart, and rechecked the drive alignment with a straight edge, and the rotation appears to be true. So, I assumed I was getting some flex somewhere that is throwing things out of alignment. I checked the subframe, and looked everywhere I could think of on the engine to make sure everything is tight.
I'm kind of at a loss as to where to look next. The pump bolts to the subframe which is attached directly to the tractor frame. Is there somewhere on the frona axle drive that can wear out, and cause movement of the engine when going forward?
