Overview
The ZF 4642.152.474 CLUTCH is a critical torque-transfer component engineered specifically for the WG 150 Series transmission. This OEM genuine part ensures precise engagement and disengagement of power flow between the engine and gearbox, directly influencing shift quality and driveline durability. As a direct replacement for the original factory assembly, the SKU 4642.152.474 sits within the clutch pack housing, interfacing with the input shaft and hydraulic control circuits. When installed alongside a 4642101109: TRANSMISSION HOUSING or a 4642301205: TRANSMISSION HOUSING, this clutch restores full clamping force and eliminates internal slippage. The part is manufactured to ZF’s strict tolerances, ensuring seamless integration with the 0730365125: TYPE PLATE identification system and the 0631311009: GROOVED STUD mounting points.
Symptoms of Failure
- Delayed or harsh gear engagement: When the 4642.152.474 clutch wears, hydraulic pressure cannot fully lock the clutch pack, causing noticeable hesitation or jarring shifts during acceleration.
- Transmission fluid overheating: Slipping clutches generate excessive friction heat, often indicated by a burning smell or elevated temperature gauge readings.
- Loss of power under load: Worn friction surfaces allow the engine RPM to rise without proportional vehicle speed, particularly noticeable on inclines or during heavy hauling.
- Metallic debris in the oil pan: Advanced clutch degradation sheds friction material and metal particles, which can be detected during routine fluid changes or filter inspections.

Compatibility
This clutch plate is primarily designed for the ZF WG 150 Series, but its dimensions and spline pattern also suit the WG 180 and WG 200 transmissions used in medium-duty trucks and off-highway equipment. It is a direct fit for models requiring the 4642.152.474 friction disc within a multi-plate clutch pack. Always verify the clutch stack height and steel plate count against your specific transmission build. For related sealing and retention components, consider the 4642301168: SCREEN SHEET and 4642301169: SCREEN SHEET for oil filtration, or the 0636100621: HEXAGON SCREW for secure fastening.
