Hey all,

Tearing into an old Chelsea PTO and need some guidance. The gear shift shaft seal is toast and I am searching for a replacement. Unfortunately the oddball shaft diameter of 0.621 is coming up with no modern equivalents. There are several options if I use a seal that is made for a 0.625 shaft. Will a seal that is designed for a shaft 0.004 larger work?
