How to find the right tool for your application

First, check the component or lock ring to determine if it requires an internal or external mounting tool. Count the number of notches or recesses in the cup or ring, and the presence of any pins. Measure the smallest outer diameter for external cups or shells; measure the largest diameter for internal rings. Use our handy template as a guide. Have you found the correct key size (index)?

Important information about the functionality of your tool

Assess the area around your work case: additional disassembly work may be necessary. The manufacturer may have manufacturing tolerances that could cause your POWER.TOOL to fit more tightly or with more play on the respective component. Verify that the tool fits precisely into/onto the component before attempting disassembly or assembly: use only the correct tool to avoid damage to the parts.
