US Patent 8931156 Puller for pulley of supercharger

A puller for removing a pulley off of the shaft is disclosed. The puller may have proximal and distal plates that are disposable around the pulley so that the pulley is disposed entirely between the proximal and distal plates. These plates are held together by frame members. A push rod is threadably engaged to a proximal plate and operative to be further inserted into the proximal plate so that a distal end of the push rod may push against the shaft and transfer a removing force through the puller to the backside of the pulley for removing the pulley off of the shaft.
