Installation & Removal

Installation and removal of the rings can be achieved in numerous ways, depending on the type of ring and the application. The most common methods are to use ring pliers to snap the rings into position for axially assembled rings, using an applicator tool for radially assembled E clips, or using a tapered mandrel to expand the ring into position. Select the right ring, and assembly tools to avoid damage to the retaining ring, the surrounding components or injury to personnel.
