20724261 Ball Socket | Genuine Volvo Penta Part

🔧 Product Description

Ball socket used in the TAD16 internal-EGR valve mechanism. It forms a low-friction articulated joint between the adjusting/actuating component and the valve bridge or caliper assembly.

🚤 Compatibility

• Engine Family: TAD, TWD
• HP Range: Approximately 750 HP
• Year Range: Approximately 2000s-2010s

Full model list at the end of this description.

⚙️ Key Features

• Precision spherical contact surface for articulated valve-mechanism movement
• Maintains alignment as the actuator and valve bridge move through their travel
• Designed for high cyclic load and engine-oil lubrication
• Works with the original adjusting screw, yoke, valve bridge and guide components
• Direct replacement for a worn, pitted or seized socket
• Engine type: 16.1 L six-cylinder turbocharged/aftercooled industrial diesel

🔌 Function

Allows the valve-mechanism linkage to transmit force while accommodating small angular movement between the actuator and valve bridge.

⚠️ Common Signs of Failure

• Excessive valve-mechanism clearance or lost motion
• Pitting, scoring or flattening of the spherical contact surface
• Ticking, knocking or uneven valve-operation noise
• Binding that prevents full valve or EGR mechanism travel
• Abnormal wear on the adjusting screw, bridge or caliper

🛠️ Service Notes

• This socket runs in engine oil as part of the TAD16 internal-EGR valve-bridge mechanism, unlike the grease-packed link-rod ball joints listed elsewhere under this item type — do not repack it with grease on assembly, and rely on the engine-oil circuit it sits in for lubrication
• The fitment list runs to more than two dozen TAD/TWD16 variants, so confirm the exact model and emissions/EDC designation before ordering rather than assuming one EGR ball socket fits the whole 16-litre range
