I am trying to fix one of my air compressors that I have laying around in the basement. I have one motor that seems to work but the pulley is missing. So I need to remove a pulley off a non-working motor and put it on a working motor. I have never done this before but I did remove the nut thing on the side and I guess I need a puller pulley set? I will try and purchase a set tomorrow from Harbor Freight.
