I'm in search of the hydraulic pump DRIVE SHAFT. The Case site shows it in the parts schematic #12 but it's listed as NSS; not sold seperately. I was hoping for a part number to search for but that was shot down. They show numbers for the parts ahead of and behind it but not the shaft. It's 19 splines and I've looked at David Brown shafts and though I've asked a LOT of people, I can't get anyone to respond as the od, spline height/depth in-between (if that matters) of theirs. So, I've a decent tractor that I can drive but can't use the bucket or 3-point. I've found shafts online that I could cut the splined end off of and weld on mine but again no one will give me the specs. I'm stuck!!! Can anyone help or suggest an alternative?
