It turns out that the parts store ordered me the wrong seal. I looked it up my self on line today and came up with a different number. I decided to remove the engine from the tractor and get it up on the bench to work on it and as soon as I removed the PTO I could see that the id of the seal was to large, but the od was correct. If I would have just checked the id against the old one I would have noticed the difference. My mistake for getting in a hurry. The worst thing is if I had looked in my spare parts cabinet I already had the correct seal. Lesson learned always check to see if you have a spare and also do not get in a hurry and install new parts with out making sure they match the old ones. I am usually good about this but got in a hurry.
Tomorrow I will get it back in the tractor and hopefully get a chance to get my sickle bar mower attached. I have a thread on it in the implements section.
Later
