Our shop teacher tried twice to get this pulley off with a puller, leaving a dimple in the end of the motor shaft with each attempt. Realizing that there must glue in the works, we got the torch and set it up ready to go. With the simple threat of heat from the torch, when the puller went on for the third time the pulley came off without actually having to apply heat. I guess the pulley knew with the gig was up and let go!
