# 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
