How to find the right tool for your application

First, check the component or lock ring to determine if it requires a tool with internal or external drive. Count the number of notches or recesses in the cup or ring, and check for 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 using your tool

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