You should measure the hole size with that fancy Harbor Freight digital caliper to be sure what you have (M8 or M10).

The hole in the pulley is 10mm. But I'm not sure if that's what the original bolt was... I think it was smaller than the hole. If I'm going to have to sleeve the threads, I might as well go back to the original sized bolt.
Course, if I do need an M10, then I'll likely have to bore out the hole bigger for the sleeve anyway, meaning I can tap it for M14xWhatever, or use a press-in insert instead of a threaded one.
