GM-50315 is a hardware kit consisting of two bolts and two washers, designed for use with GM-8433-1 Puller and GM-22912-B Bearing Remover to remove the rear output shaft bearing from the shaft. GM-22912-B has 3/8"-24 threaded holes, and SAE bolts are not commonly available in most global areas. GM-50315 includes two bolts 7-1/2" long, and two washers. GM-22912-B installs around the bearing, and the hardware from GM-50315 is installed through GM-8433-1, then attached to GM-22912-B. The forcing screw from GM-8433-1 is tightened against the output shaft to remove the bearing. Unapproved methods will damage the bearing.
