ABSTRACT:
A bearing puller that pulls an alternator bearing from a shaft. The bearing, when pulled, travels over slip rings on the shaft which are not affected by the pulling action. A "U" shaped frame has a pair of laterally spaced legs with free ends that abuttingly engage a pole piece of the alternator and an elongate screw is threadedly received by the frame so that rotation of the screw translates into axial travel of the screw and a bearing gripper member secured to the screw. The gripper member performs the pulling function when the screw is rotated.
