I guess a lot of the PTO's were made for the 3-speed trans. I have a 4-speed. So the drive shaft is 3" too short. No worries. While I was at it I tore apart the pillow block body. That was because it wouldn't turn. What I found out was, Still available from Toyota: Bearing Snap ring (holds bearing in place) Large dust seal (made of felt) Dust seal retainer Not available anywhere I could find: Small dust seal Large washer. Here are some pics that shows what is where. Oh, and how I lengthened the PTO drive shaft.
