ZF 4644.153.085 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.153.085 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 planetary gear set assembly, where it engages and disengages power flow between the engine and drivetrain. The SKU 4644.153.085 is manufactured to ZF’s exacting tolerances, ensuring precise hydraulic actuation and consistent clamping force under heavy-duty industrial loads. When installed alongside the 4644101144 TRANSMISSION HOUSING, this clutch forms the backbone of reliable gear engagement in construction and agricultural machinery.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn friction discs in the 4644.153.085 cause hesitation when shifting from neutral to drive, often accompanied by a jarring thud.
• Transmission overheating under load: A slipping clutch generates excessive heat, leading to burnt transmission fluid odor and elevated temperature warnings on the dashboard.
• Oil leaks near the bell housing: Degraded piston seals within this clutch assembly allow hydraulic fluid to escape, leaving visible drips around the 4644301304 HOUSING interface.
• Loss of power during uphill operation: The clutch fails to maintain lockup, causing the transmission to slip and lose torque transfer when climbing grades or hauling heavy loads.

Technical Specifications

Compatibility

This clutch is designed for ZF WG 180 and WG 200 series powershift transmissions commonly found in wheel loaders, forklifts, and telehandlers. It directly replaces the original clutch pack in models such as the WG180, WG200, and their variants (WG180/200/211). The 4644.153.085 interfaces with the 0730365067 TYPE PLATE for correct orientation and is secured using the 0631311009 GROOVED STUD. Always verify your transmission serial number against ZF’s parts catalog before installation.
