Jerry,
The seal will only see slight lateral force when shifting the PTO gear in and out, but the seal is below the transmission fill plug so it will be constantly immersed in 90 weight gear oil. The "close" 0.625 inch seal does have the garter spring. The application is a 1942 non-syncro 4-speed under atmospheric pressure.
From your advice it sounds like the garter spring can "absorb" a certain range of shaft diameter? Any ball park rule of thumb on this kind of stuff?
Thanks, you have been a big help.
Paul
