The shaft is 0.785" and the required spacing is 3/8", just FYI. I cut the spacer to 3/8" and dremelled out the inner surface until it fit on snugly with a little effort. Remember, the idler pulley also needs a 3/8" spacer (or washers, since they don't spin)!!!

I bought a 3/8-24 x 2" bolt for the jackshaft and I used the old jackshaft bolt for the new SC pulley.

Also FYI, I had an old 8-rib belt lying around that I used to wrap the SC pulley while loosening the pulley bolt.

I can get pictures of the specifics, if desired.
