Overview
The ZF 4642.152.066 CLUTCH is a critical torque-transfer component engineered specifically for the WG 150 Series transmission. This OEM genuine part sits within the forward clutch pack assembly, engaging and disengaging planetary gear sets to facilitate smooth gear shifts under heavy load. As a direct OEM replacement, the SKU 4642.152.066 ensures precise hydraulic pressure control and consistent friction engagement, directly influencing driveline efficiency and operational uptime. When paired with a robust TRANSMISSION HOUSING (4642101108) or a TRANSMISSION HOUSING (4642301208), this clutch maintains the structural integrity required for high-torque industrial applications.
Symptoms of Failure
- Delayed or harsh engagement: A worn 4642.152.066 clutch often causes noticeable lag when shifting from neutral to drive, or abrupt engagement that jars the driveline.
- Transmission slipping under load: If the clutch disc friction material is depleted, the transmission may slip during acceleration or while climbing grades, reducing power transfer efficiency.
- Burnt transmission fluid odor: Overheated clutch plates generate a distinct burnt smell in the hydraulic fluid, indicating imminent clutch failure and potential contamination of the TYPE PLATE (0730365125) identification area.
- Erratic shift patterns: Worn clutches cause inconsistent hydraulic pressure, leading to unpredictable upshifts or downshifts that can stress the GROOVED STUD (0631311009) mounting points.

Compatibility
This clutch is primarily designed for the ZF WG 150 transmission series. Based on its dimensional characteristics and spline configuration, the 4642.152.066 CLUTCH is also compatible with the WG 180 and WG 200 models, which share similar clutch pack architectures. It may be utilized in WG 120 variants where the clutch drum diameter matches. For exact fitment verification, always cross-reference the part number against your transmission’s TYPE PLATE (0730365125) to confirm OEM specifications.
