ZF 4644.152.072 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.152.072 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series powershift transmissions. This OEM genuine part, identified by SKU 4644.152.072, sits within the clutch pack assembly and is responsible for engaging and disengaging gear sets under load. It directly interfaces with the TRANSMISSION HOUSING (4644101217) and the TRANSMISSION HOUSING (4644301383) to ensure precise hydraulic pressure distribution. Without a properly functioning clutch, the transmission cannot maintain consistent power flow, leading to operational inefficiency in heavy-duty industrial applications.

Symptoms of Failure

• Delayed or harsh gear engagement: When the 4644.152.072 clutch wears, hydraulic pressure drops, causing noticeable lag or jerking when shifting between forward and reverse gears.
• Torque converter shudder under load: A failing clutch often produces a vibration or shudder during acceleration, particularly in WG 200 models operating at high torque.
• Burning smell from transmission fluid: Slipping clutch plates generate excessive heat, leading to fluid degradation and a distinct burnt odor.
• Intermittent loss of drive in specific gears: Worn clutch friction material can cause the transmission to momentarily lose power, especially in lower gear ranges.

Technical Specifications

Compatibility

This clutch is designed for ZF WG 180 and WG 200 series transmissions, including the WG 181 variant. It is also compatible with the WG 182 and WG 202 models where the clutch pack configuration matches the 152 mm outer diameter. The part integrates with the THREADED BUSH (4644301189) for precise alignment and the SCREW PLUG (4475280043) for sealing the hydraulic circuit. Always verify your transmission serial number against ZF documentation to confirm fitment.
