So I tried to remove the pulley again. I tried Bill’s suggestion on heating the pulley. It worked heating the shaft but now the puller and this little metal piece (in the second picture) is not allowing the puller to pull. I gave up for now.
Original Post link Bill’s quote: “I have done the same, breaking a stuck pulley. 2 ways you could have removed the pulley. 1. heat the shaft with a cutting torch. The heat would have expanded the pulley and the puller would have removed it. by putting some tension on the puller first, and then adding heat, the pulley would have popped free. 2. Since the motor was junk anyways, you could have cut the motor shaft off with the pulley attached, and either had it pressed out at a auto parts store, or put the pulley loosely on top of a vise and hammered the shaft through to remove it. Always and I do mean always use antisieze on everything you assemble to help you at a future time in case it ever needs disassembly.”
