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
