🔌 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
