# 3858852 Retainer | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta retainer weighing 0.923 kg. It supersedes part number 884763, which was catalogued earlier as a tool, so the current number moves this item from a workshop-tool listing to a fitted part - worth confirming which of the two you need. No engine applications are published against the number, so identify it from the assembly it came out of.

## ⚙️ Key Features

-   0.923 kg
-   Supersedes 884763, catalogued earlier as a tool
-   Substantial for a retainer at almost a kilogram

## 🔌 Function

Holds a component captive in its housing, taking the load that would otherwise push it out of position.

## ⚠️ Common Signs of Failure

-   Component it holds working loose or moving in service
-   Knocking or rattling from the assembly under load
-   Retaining faces bruised, stepped or spread
-   Fixing threads or holes pulled, elongated or damaged
-   Corrosion or scoring where it clamps

## 🛠️ Service Notes

-   The old number being listed as a tool means descriptions from the previous entry can be misleading - order against the assembly, not the old name
-   Retainer 3859083 is a much lighter Engine group retainer at 0.112 kg and is not an alternative to this one
