All of a sudden I can upload pic's to go with the above wheel motor post / install. The pictures were not in the order I selected but you can fill in the blanks. Hopefully this may help someone else with an older machine.
Shows the difference between my old Parker Wheel motor / hubs and the newer White motor with thicker hubs, sent to me from Terry. The newer motor did not have a case drain so I had to cap that hose off.
The motor was too long I ended up having to move the lift cylinder over and the pin out of the way so it would fit into the mount area. I only made it by about 1/8 of an inch. After I turned the pin around.
So far the new motor is working great and I can't tell the difference. I have installed my new loaded tires they seem to be very stable easy on the grass and I really like the ride over the Bar tires that originally came with the PT.
I also just ordered a new seat, the same stock seat but with arm rests. I like the stock seat because it has length wise metal backing more protection for my back in case of a engine fire etc.
I will be upgrading gradually starting with a Rop's in the not so distant future. Once again thanks for all of the tips and help.
