ZF 4644.153.429 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.153.429 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series transmissions. Positioned within the hydraulic control circuit, this OEM genuine part engages and disengages power flow between the engine and drivetrain, ensuring smooth gear shifts under heavy loads. The SKU 4644.153.429 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in industrial machinery, construction vehicles, and agricultural equipment. Without a properly functioning clutch, the transmission cannot maintain consistent power delivery, leading to operational inefficiency.

Symptoms of Failure

• Transmission gear slipping under load: When the 4644.153.429 clutch wears, the friction material loses grip, causing the transmission to slip during acceleration or uphill travel. This often manifests as a sudden RPM spike without corresponding speed increase.
• Delayed or harsh engagement: A failing clutch may cause a noticeable lag between shifting and actual gear engagement, or produce a jarring “clunk” when the transmission finally catches. This symptom is common in WG 200 series units with high operating hours.
• Overheating transmission fluid: Excessive clutch slippage generates abnormal heat, which degrades the hydraulic oil and can trigger thermal warnings. If you notice burnt-smelling fluid or dashboard temperature alerts, inspect the 4644.153.429 immediately.
• Oil leaks near the clutch housing: Worn seals or cracked clutch plates can allow transmission fluid to escape, leaving puddles under the vehicle. This is often accompanied by low fluid levels and erratic shifting.

Technical Specifications

Compatibility

This clutch is designed for the ZF WG 180 and WG 200 transmission families, including the WG 201 Series category. It directly fits models such as the WG180, WG200, and WG201. The 4644.153.429 is also compatible with certain variants of the WG 150 series when used with the correct TRANSMISSION HOUSING (4644101160) or the TRANSMISSION HOUSING (4644301323). Always verify the clutch stack height against your transmission’s service manual before installation.
