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.
