## 🔌 Function

Retains a pin or shaft in its bore, seating in a groove so the assembly cannot work its way out.

## ⚠️ Common Signs of Failure

-   Knocking or rattle from the assembly the ring retains
-   Ring found sprung open, distorted or out of its groove
-   Wear ridge or bright marking on the groove wall
-   End float where the assembly should be held tight
-   Ring cracked at an ear or eye

## 🛠️ Service Notes

-   Fit a new ring every time rather than reusing one that has been sprung off, as they take a set
-   Check the groove for wear or ridging before fitting, since a worn groove will let a new ring out again
-   Confirm the 28 mm diameter against the ring you are removing
