ZF 4644.130.475 ENGINE CONNECTION for WG180/WG200 | OEM Genuine Part

Overview

The ZF 4644.130.475 ENGINE CONNECTION is a critical OEM genuine coupling component designed specifically for the WG 180 and WG 200 transmission series. This precision-engineered part serves as the primary mechanical interface between the transmission assembly and the engine flywheel housing, ensuring accurate alignment and secure power transfer. As a factory-specified replacement, the SKU 4644.130.475 guarantees exact fitment and durability under high-torque industrial applications. When installed alongside the 4644105475: DISCONNECTION and the OUTPUT FLANGE, this engine connection forms the backbone of the driveline integrity.

Symptoms of Failure

• Transmission oil leaks at the bell housing interface: A worn engine connection often causes fluid seepage between the transmission and engine, leading to low oil levels and potential overheating.
• Gear slipping under load: When this part fatigues, misalignment occurs, causing intermittent power loss and erratic shifting during heavy-duty operation.
• Abnormal vibration or knocking sounds: A degraded connection produces audible metallic rattling, especially during acceleration or deceleration, indicating loose coupling.
• Difficulty engaging or disengaging the transmission: Mechanical binding at the connection point can make gear selection stiff or unresponsive, often mistaken for clutch issues.

Technical Specifications

Compatibility

This engine connection is engineered for the ZF WG 180 and WG 200 series transmissions, commonly found in medium-duty trucks, construction equipment, and agricultural machinery. It directly interfaces with the TRANSMISSION HOUSING and is secured using the HEXAGON SCREW fasteners. While primarily designed for WG180 and WG200 models, it may also be retrofitted to certain earlier ZF power take-off configurations. Always verify your transmission serial number before ordering.
