Overview
The ZF 4642.152.201 CLUTCH for WG 150 is a critical torque-transfer component engineered for the WG 150 series transmission. This OEM genuine part ensures precise engagement and disengagement of the driveline, directly managing power flow from the engine to the gearbox. Positioned within the clutch housing assembly, the 4642.152.201 clutch operates under high thermal and mechanical stress, making its integrity essential for smooth shifting and load handling. As a direct replacement, this SKU guarantees factory-specified tolerances and material composition, restoring original performance in heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4642.152.201 clutch begins to wear, operators often notice intermittent gear slipping under load, particularly during uphill or high-torque maneuvers. Another common indicator is delayed or harsh engagement when shifting from neutral to drive, accompanied by a noticeable shudder. Over time, oil leaks near the clutch housing may develop as seals degrade, leading to low transmission fluid levels. Additionally, burned clutch odor or dark, contaminated fluid signals excessive friction material wear, requiring immediate inspection of the 4642.152.201 unit.

Compatibility
This clutch is primarily designed for the ZF WG 150 transmission, but it also fits select models in the WG 180 and WG 200 series due to shared clutch pack architecture. It is commonly used in off-highway vehicles, forklifts, and material handling equipment where the WG 150 gearbox is specified. For proper installation, ensure the TRANSMISSION HOUSING (4642101109) and TRANSMISSION HOUSING (4642301205) are free of cracks or warping. The TYPE PLATE (0730365125) should be verified for correct model identification, and the GROOVED STUD (0631311009) must be torqued to factory specifications during reassembly.
