468727 Spring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta spring from the Lubricating and Oil System group, for use in 471707, and listed for 39 applications across TMD, THD, TID, TD, TAMD and DH series engines. It supersedes part number 468729, which was catalogued earlier as a relief valve, so the old number supplied a complete valve where this supplies only the spring.

🚤 Compatibility

• Engine Family: TMD, THD, TID, TD, TAMD, DH, TAD

⚙️ Key Features

• For use in 471707
• 39 applications across six engine series
• Supersedes 468729, catalogued earlier as a relief valve

🔌 Function

Sets the pressure at which the relief valve lifts, so surplus oil is spilled and the rest of the system holds pressure.

⚠️ Common Signs of Failure

• Oil pressure low, or dropping away when hot
• Pressure unsteady at idle
• Spring collapsed, shortened or broken
• Relief plunger sticking in its bore
• Debris held under the valve seat

🛠️ Service Notes

• The old number was a complete relief valve, so check whether the valve body and plunger also need renewing rather than fitting the spring alone
• Spring 466445 is the equivalent for assembly 471812 and carries the same unusable published weight, so order by the assembly number
