## 🔌 Function

Locks a component axially in its bore or on its shaft so it cannot work loose.

## ⚠️ Common Signs of Failure

-   Component it retains found loose or able to move endwise
-   Ring sprung open, distorted or missing from its groove
-   Groove edges worn or hammered
-   Rattle or ticking from the assembly the ring holds

## 🛠️ Service Notes

-   Use the correct pliers — a lock ring stretched past its elastic limit will not hold
-   Fit new rather than reusing; the cost is trivial next to the consequence of it letting go
