Abstract:
1. A puller for removing a pulley mounted to a shaft of a super charger, the puller comprising: a distal plate having an opening sufficiently large to receive the shaft and a portion of the super charger where the shaft is mounted to the portion of the supercharger, the opening being smaller than a distal end of the pulley, the distal plate having three attachment points disposable about a central axis of the puller; a proximal plate having three attachment points disposable about the central axis of the puller, the attachment points of the proximal plate being in alignment with the attachment points of the distal plate, the proximal plate having a threaded hole axially aligned to the central axis of the puller; three elongate frame members defining distal and proximal end portions, the distal end portions of the three frame members attached to the three attachment points of the distal plate, the proximal end portions of the three frame members attached to the three attachment points of the proximal plate; a push rod threadably engaged to the threaded hole of the proximal plate, the push rod having a wrench engaging portion for rotating the push rod and a distal portion sized and configured to engage a proximal end of the shaft of the super charger; wherein clockwise rotation of the push rod traverses the distal portion of the push rod into engagement with the proximal end of the shaft of the super charger and creates an opposing force on the distal end of the pulley with the distal plate to pull the pulley off of the shaft of the super charger; wherein the threaded hole of the proximal plate comprising a recess formed on a distal side of the proximal plate and an insert with the threaded hole, the insert being retained within the recess.
