I am trying to install a Letourneau PCU to my 2T D4. I need to couple the PCU to the tractor. The PCU is Male 1 3/4" OD 10 spline SAE shaft. Need to connect to D4 rear PTO shaft. Would anyone have the parts I need for sale. Cannot find 1 3/4" OD 10 spline coupler at ag implement dealers. Any Ideas who would have parts. Thanks Mark in colorado 970-two nine zero-5432.

Looks like you will need original Letourneau parts.

If www.hubcityinc.com doesn't have it, it doesn't exist and I could not find 1-3/4" 10 spine in their listing.

You might find an automotive drive line yoke, just turn off the yoke and keep the barrel. It will be sized for a slip-fit, but you could use a tighter male spline if you have to make that part. You could also use one of the newer style splined ends that are coated with nylon and weld it to your shaft. Last resort would be to make the coupling by broaching with a keyway broach: you use a broach plug with a pin at 36 deg to index the plug around the bore for successive cuts.
