D6 9U PTO and Parts

Hello all,
I am a new member and have been avidly looking for information on these tractors. I currently own a 9U19877 and 9U 16???. I would like a lead to good places to search for parts where someone knows what I am talking about. Or if someone knows of a pto unit for these somewhere I would like to find one. Converting the old one back to a farm purpose tractor to use and to power a 1926 Sears Roebuck circle mill. Thanks for the help. The Library is awesome and getting me into trouble with the wife. Lol

you can get about 75% of your parts right from caterpillar. most stuff is available or just google the part number you'll see aftermarket places. machinery trader has parts look up side to it.

Ill try a pic of my PTO unit .. They are hard to find !!. Ive just had a new shaft made for one .. Cat dont have any more ...

Pete: Why would a shaft from a Be-Ge hydraulic unit not work? I am guessing same length, what about the spline size and count? One day I will find a PTO for a 9U myself. Best of luck. JM
