# 11030662 Retaining Ring | Genuine Volvo Penta Part

## 🔧 Product Description

This is a genuine Volvo Penta retaining ring, a small circlip-style locking component used to secure a shaft or bore-mounted part in its correct axial position. It is specified for TD164, TWD1240 and TWD16-series industrial and generator-set engines as well as the TWD1744GE. Because retaining rings are single-use in most assemblies, fitting a new one whenever the joint is disturbed is recommended.

## 🔌 Function

A retaining ring seats into a machined groove to lock a shaft, pin or bearing against axial movement within an assembly. It holds the mating components in their designed position while allowing rotation or float where required.

## ⚠️ Common Signs of Failure

-   Ring has spread, lost tension or no longer seats fully in its groove
-   Visible distortion, stretching or cracking of the ring after removal
-   Retained component moving axially, knocking or working loose in service
-   Wear or scoring in the groove and on adjacent faces from a displaced ring
-   Missing ring found during teardown, often with related debris in the housing

## 🛠️ Service Notes

-   Fitted inside water pump 3830046 and included in repair kit 11990043 — order the kit if you're servicing the pump rather than sourcing the ring alone
-   Fit a new ring rather than reusing the old one, and use correctly sized circlip pliers so it isn't overstretched going in
