ZF 4644.153.211 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.153.211 CLUTCH is a critical torque-transfer component engineered for the WG 180 and WG 200 series powershift transmissions. Positioned within the clutch pack assembly, this OEM genuine part engages and disengages gear sets by applying hydraulic pressure to friction discs, enabling smooth directional shifts and load-holding capability under heavy-duty operation. The SKU 4644.153.211 is specifically designed for the WG 181 Series, ensuring precise fitment and factory-specified clearance within the transmission housing. When paired with a robust 4644101217: TRANSMISSION HOUSING or the 4644301383: TRANSMISSION HOUSING, this clutch maintains optimal oil flow and piston actuation for reliable performance in construction and agricultural machinery.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn clutch plates cause hesitation or abrupt shifting when the transmission is under load, often accompanied by a noticeable shudder.
• Transmission oil overheating: Slipping clutches generate excessive friction, raising oil temperatures beyond normal operating ranges and accelerating fluid degradation.
• Loss of power during uphill operation: The clutch fails to hold torque, resulting in RPM flare without corresponding vehicle movement, especially on inclines.
• Metallic debris in transmission fluid: Friction material wear deposits fine metal particles in the oil, visible during routine drain intervals and indicating imminent clutch failure.

Technical Specifications

Compatibility

This clutch is engineered for the ZF WG 180 and WG 200 transmission families, including the WG 181 Series. It is directly compatible with models such as WG 180, WG 181, WG 200, and WG 201 used in wheel loaders, telehandlers, and industrial tractors. The part also interfaces with the 4644301189: THREADED BUSH for precise piston alignment and the 4475280043: SCREW PLUG for sealing hydraulic circuits. Always verify transmission serial numbers before installation to ensure correct clutch pack stack height.
