This special tool is designed to remove and install the pulley on Ford (and Eaton) superchargers. The replacement of the press-on supercharger pulley for the Ford series superchargers (Cobra, Lightning and Harley-Davidson trucks) is a staight-forward procedure with this tool, but does require that the engine be completely cooled down before removal of the existing pulley or installation of the replacement pulley.
The best procedure is to allow the car/engine to sit overnight before beginning the procedure.
