ZF 4644.152.418 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.152.418 CLUTCH is a critical internal component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part functions as the primary torque transfer interface, engaging and disengaging power flow between the engine and the gear train. Positioned within the main shaft assembly, the 4644.152.418 clutch ensures smooth gear shifts and reliable power delivery under heavy-duty industrial loads. When replacing this unit, it is essential to also inspect the 4644105424 DISCONNECTION mechanism to ensure proper alignment and engagement within the housing.

Symptoms of Failure

• Delayed or harsh engagement: A worn clutch causes noticeable hesitation or a jarring “clunk” when shifting from neutral to drive, indicating loss of friction material integrity.
• Transmission slipping under load: If the engine revs increase without proportional vehicle speed during uphill climbs or heavy hauling, the 4644.152.418 clutch is likely failing to maintain grip.
• Contaminated transmission fluid: Excessive clutch wear generates dark, burnt-smelling debris in the oil, often visible during routine fluid checks or filter changes.
• Intermittent loss of power: A failing clutch can cause sudden, momentary power drops during acceleration, particularly in WG 200 series units operating at high torque.

Technical Specifications

Compatibility

This clutch is designed for the ZF WG 180 and WG 200 series transmissions, which are commonly found in municipal trucks, construction vehicles, and heavy-duty buses. It directly replaces the original equipment clutch pack in these models. For proper installation, ensure the 4644303538 OUTPUT FLANGE is free of wear, and use a new 0636021036 HEXAGON SCREW to secure the assembly to the 4644101224 TRANSMISSION HOUSING. The 4644.152.418 is not backward-compatible with WG 120 or earlier series without significant modification.
