Overview
The ZF 4644.152.482 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part sits within the forward clutch pack assembly, where it engages and disengages power flow between the engine and the drivetrain. The SKU 4644.152.482 ensures precise hydraulic actuation and consistent clamping force, making it indispensable for maintaining smooth gear shifts under heavy-duty industrial loads. When paired with the 4644105424 DISCONNECTION mechanism, this clutch delivers reliable performance in demanding construction and agricultural machinery.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn 4644.152.482 clutch often causes a noticeable lag when shifting from neutral to drive, or produces a jarring thud during engagement.
- Torque loss under load: If the clutch slips under heavy acceleration or uphill operation, the friction material has likely degraded, reducing power transfer efficiency.
- Contaminated transmission fluid: Failing clutches shed debris into the oil, leading to dark, burnt-smelling fluid that can clog the 4644306563 VALVE BLOCK.
- Erratic shifting patterns: Intermittent clutch grab or release causes unpredictable shift points, often accompanied by vibration through the 4644303538 OUTPUT FLANGE.

Compatibility
This clutch is designed for ZF WG 180 and WG 200 series transmissions, commonly found in wheel loaders, forklifts, and mobile cranes. It directly replaces the original clutch pack in models with serial numbers starting from 2015 onward. The part also interfaces with the 4644101224 TRANSMISSION HOUSING and requires the 0636021036 HEXAGON SCREW for secure mounting. For complete rebuilds, verify compatibility with your specific transmission tag using the 0730365067 TYPE PLATE.
