Overview
The ZF 4642.151.201 CLUTCH is a critical torque-transfer component engineered specifically for the WG 150 series transmission. This OEM genuine part sits within the clutch pack assembly, managing the engagement and disengagement of planetary gear sets to facilitate smooth gear changes under heavy load. The SKU 4642.151.201 is precision-machined to ZF’s exacting tolerances, ensuring consistent hydraulic pressure application and minimal power loss during operation. When installed alongside the 4642101109: TRANSMISSION HOUSING and the 4642301205: TRANSMISSION HOUSING, this clutch delivers the durability required for industrial driveline applications.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn friction plates cause hesitation or jarring shifts, especially when accelerating from a stop.
- Transmission oil leaks near the clutch housing: Degraded seals allow ATF to escape, leaving visible puddles under the vehicle or equipment.
- Gear slipping under load: The clutch fails to hold torque, causing RPM flare without corresponding speed increase during uphill or loaded operation.
- Burning smell from transmission fluid: Overheated clutch material contaminates the oil, producing a distinct acrid odor and darkening the fluid.

Compatibility
This clutch is primarily designed for the ZF WG 150 transmission series. Based on its construction and spline pattern, it is also compatible with the WG 180 and WG 200 models when used in low-range or auxiliary gear applications. For proper installation, verify the clutch stack height against the 0730365125: TYPE PLATE affixed to your transmission housing. Additionally, the 0631311009: GROOVED STUD must be torqued to specification to secure the clutch pack assembly.
