Got a break in the weather today so I pulled the pump. Can't get it out of the tractor with the cooler above it in place but I was able to turn it around, look at the splines and also peer and poke a finger down the drive shaft. There is about an inch and a quarter of splines on the pump, and a corresponding depth in the hole in the end of the drive shaft. The first third or so of the shaft hole has no splines, it feels like there used to be. It is normally splined all the way to the end, correct? About a corresponding amount of the splines on the pump seemed to be plugged with debris or worn metal. I'm guessing the pump was only engaging the first third of the available spline length. In fact, it looks like if I removed the drive shaft, cut off the part with not splines left and spaced it out from the crank (or lengthened it somehow), I could potentially end up with more spline area engaged than before. What is involved in removing the shaft, just unbolt from the crank? What is there where it passes through the tractor frame, just 40 years of muck?
