ZF 4661.272.021 CLUTCH for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.272.021 CLUTCH is a critical friction component engineered for the WG 90 and WG 94 series transmissions. This OEM genuine part manages torque transfer between planetary gear sets, ensuring smooth engagement and disengagement during load shifts. Positioned within the hydraulic control circuit, the clutch assembly directly influences gear ratio selection and power flow. The SKU 4661.272.021 is precision-machined to factory tolerances, making it essential for restoring original shift quality in heavy-duty applications. When paired with the 4661101033 HOUSING and the 4661301096 HOUSING, this clutch ensures correct alignment and oil distribution within the transmission.

Symptoms of Failure

• Delayed or harsh engagement: Worn friction material causes hesitation when shifting from neutral to drive, often accompanied by a jarring thud.
• Transmission slipping under load: The clutch fails to hold torque, resulting in RPM flare without corresponding vehicle acceleration, especially on inclines.
• Burning odor from transmission fluid: Overheated clutch plates produce a distinct burnt smell, indicating imminent failure and potential damage to the 0631306174 CYLINDRICAL PIN.
• Oil contamination with metallic debris: Shedding friction material circulates through the system, clogging valves and scoring the 0769123894 TYPE PLATE.

Technical Specifications

Compatibility

This clutch is specifically designed for the ZF WG 90 and WG 94 series transmissions. It also fits select models in the WG 180 and WG 200 families where the same clutch pack configuration is used. Always verify the clutch count and spline profile against your transmission’s service manual. For complete assembly, this part works with the 0750100022 SCREW PLUG and 4660201008 SCREW PLUG to seal hydraulic passages.
