Would anyone know the size or specs of the left hand thread countersunk bolt and cone washer for a Massey Ferguson vari-speed pulley? I don't know if the "Variator" on some John Deeres might be the same thing. I want to get one and pull the pulley apart, fill it with oil and check the bushings. I do remember the screw was getting a little buggered up. Thinking I may be able to order one from Fastenal unless someone knows a source---or better yet one I could buy from a member?!

How about the left hand countersunk screw that holds a drill chuck on the shaft? Would it be too small? OD is .232" and I can't tell what the pitch is tho it looks kinda fine. I know about how to replace these using the drill to crank small engines over. If it fires once the screw is pulled into.

I'm not sure if a chuck screw would be the same or not, Mike. It's been several years since I had it apart and I didn't take good enough notes to reference later. Hopefully I get one before I try to remove the old one!
