Abstract: A hand held integral gauge for comparing automotive starters so that a replacement starter will accurately match the starter being replaced, to avoid poor engagement and premature failure of flywheels and starters. The gauge is compact, easy to use and manufacture, and consists of only three main parts. The gauge is mounted on the starter to be replaced to get initial measurement (in ten thousandths). The gauge is then mounted in the same way on the replacement starter to compare, thus determining an accurate fit.

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.
