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 in the cup or ring, and any pins present. 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 operation of your tool:

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