How to find the right tool for your application

First, check the component or lock ring to determine whether it requires an internal or external mounting tool. Count the number of notches or recesses present in the cup or ring, and check for the presence of pins. Measure the smallest outer diameter for external cups or shells, or the largest diameter for internal rings. Use our handy template as a guide.

Important information on the operation of your tool

Assess the area around your work: further disassembly may be necessary. The manufacturer may have manufacturing tolerances that can cause your POWER.TOOL to fit tighter or looser on the component. Before attempting disassembly or assembly, verify that the tool fits perfectly into/onto the part. Use only the correct tool to avoid damage to components.
