ZF 4644.151.479 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.151.479 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part, identified by SKU 4644.151.479, sits within the hydraulic control assembly where it modulates power flow between the engine and the gear train. Designed to withstand high thermal loads and continuous duty cycles, this clutch ensures precise engagement and disengagement during shifting operations. When paired with a properly functioning DISCONNECTION unit, it maintains consistent pressure regulation across the transmission system.

Symptoms of Failure

• Delayed or harsh gear engagement – Worn clutch plates cause hesitation when shifting from neutral to drive, often accompanied by a noticeable thud.
• Transmission fluid overheating – Slipping internal components generate excess heat, leading to burnt fluid odor and reduced lubrication efficiency.
• Intermittent power loss under load – The clutch fails to hold torque during acceleration, resulting in RPM flare without corresponding vehicle speed increase.
• Oil leaks near the bell housing – Degraded seals around the clutch piston allow hydraulic fluid to escape, leaving visible drips on the transmission exterior.

Technical Specifications

Compatibility

This clutch is designed for ZF WG 180 and WG 200 series transmissions used in heavy-duty construction equipment, agricultural machinery, and municipal vehicles. It directly replaces the original factory component in models such as WG180-1, WG180-2, WG200-1, and WG200-2. For complete assembly restoration, verify the condition of the OUTPUT FLANGE and the TRANSMISSION HOUSING, as these components frequently require simultaneous replacement. Secure the clutch using the specified HEXAGON SCREW torque values to prevent premature wear.
