No way that I know of to remove and replace the supercharger pulley without the puller/installation tool. There was a guy in my area a while ago that had one and he installed my pulley but I lost touch with him. Try to find shops that have worked on cars with Eatons or check out those forums. Eaton Superchargers are used on Ford Mustangs, Chevy Cobalt's, Impala SS models, Buick Rivera's , Pontiac Bonneville's and Pontiac Grand Prix. There should be many people in your area, with the means to change the pulley. A Mustang shop or performance enthusiast might be in your area. Try Realspeed Automotive . They are on LI near MacArthur airport.
