## ⚙️ Key Features

-   Factory diameter and groove profile
-   Controls axial component movement
-   Spring-steel retaining construction
-   Designed for the assigned shaft or housing groove

## 🔌 Function

The ring engages a machined groove to retain the associated component against axial movement.

## ⚠️ Common Signs of Failure

-   Ring loose in the groove
-   Distortion or cracking
-   Component end float
-   Ring dislodging during operation

## 🛠️ Service Notes

-   Used across the D4-260 and D4-300 series listed for this ring - confirm your exact engine variant, since Volvo Penta fits several similarly sized retaining rings through this range that are not always interchangeable between positions
-   At 0.007 kg this is a light ring for a drivetrain position - check the shaft or housing groove for wear or a widened gap before fitting a replacement, since a worn groove will let even a new ring work loose
