ZF 4644.151.066 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.151.066 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series transmissions. Positioned within the planetary gear set assembly, this OEM genuine part manages the engagement and disengagement of power flow between the input shaft and the intermediate housing. The SKU 4644.151.066 ensures precise hydraulic actuation and consistent clamping force under heavy-duty industrial loads. When paired with a properly sealed 4460115043: HOUSING, this clutch assembly maintains optimal oil pressure and reduces thermal stress during prolonged operation.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn friction plates in the 4644.151.066 cause hesitation or abrupt shifting, especially when the transmission is cold.
• Intermittent power loss under load: A failing clutch slips during acceleration, leading to a noticeable drop in torque delivery to the 4469315012: AXLE DRIVE HOUSING.
• Contaminated transmission fluid: Debris from degraded clutch material turns the oil dark and gritty, accelerating wear on adjacent 0750117406: TAPER ROLLER BEARING components.
• Audible grinding or whining: Metal-to-metal contact inside the clutch pack produces a distinct noise, often accompanied by vibration through the driveline.

Technical Specifications

Compatibility

This clutch is engineered for the ZF WG 180 and WG 200 transmission families, including the WG180, WG200, and their derivative models (e.g., WG180C, WG200C). It directly interfaces with the 0750117802: TAPERED ROLLER BEARING set that supports the output shaft. Always verify your transmission serial number against the OEM parts catalog to confirm fitment, as variations exist between early and late production runs.
