I rebuilt motor, but having trouble with clutch and right steering clutch. Any advise would be helpful. Thanks.

Think I need to replace, but don’t know where to get parts. I also need to know what and how much transmission oil?

Circle-G Tractor and Keno Tractor are also parts sources as well as many others. See the dealer directory above. The transmission and bevel gear case share the same sump, and use 85w-90 gear oil. Fill to the line on the dipstick. Do not thread the dipstick in when measuring. Sounds like you have some broken steering clutch linkage inside. Check your parts manual.
