This is a hydraulic oil pump from one of our skip loaders. It is the third to fail on two different tractors. Of course, you have to replace the entire pump - no sub parts available.

It mounts to the front of the crank. The spline only engages about half its length.

Pump is $1100!

Anyone have an idea on how to repair the spline? A welding technique? We are experimenting with drilling and inserting a pin/key - we've got nothing to lose on the old parts.

Any better ideas? Any help would be most appreciated.
