Hello everyone. I am somewhat getting back into the IH Cub Cadet game and have a question. What is the diameter of the bevel pinion shaft where the constant mesh gear rides on a hydro rearend? I need to remove the constant mesh gear and replace it with a 10 tooth #60 chain sprocket for a project I will be starting soon. I know the shaft is splined at this point but I will use the constant mesh gear to machine a hub for the sprocket.

The project is putting a cub 1650 rearend into a Snapper/Massey Ferguson 1650 as part of a four wheel drive conversion (Suzuki LJ10 jeep front axle, cub 1650 rearend, '68 Ford Bronco transfercase, hydraulic drive).

Thanks,
Patrick
