Johndeere3720:
Thanks for the help with my problem. I am going to assume that you read my post to 'clemsonfor' above.
I looked at your tear-down pictures along with your copy of the manual. I do have the manuals that go with the tractor.
My understanding from looking at what you posted is that the drive to the rear tractor wheels and the PTO are directly related yes? That is to say some components are shared between the functions of running the tractor drive-train and running the PTO.
Do you have to remove the tire to get at the PTO or was that to facilitate your access to the seal you mentioned?
I was intending to call HOYE today and talk with them about this issue to see what feedback I'd get. Any other source of technical help you know about?
Thanks again for the assist.
Jon
