Once engaged, the tool's plastic guide will fit in to the near-side shell opening to hold the tool steady while you tap the handle end firmly with a hammer, until the bearing pops out. To install new bearings, the bundled bushings are used with a head cup press (not included) to quickly and accurately press the bearings in to the shell.
