ZF 4651.153.004 CLUTCH for WG 100/WG 110 | OEM Genuine Part

Overview

The ZF 4651.153.004 CLUTCH is a critical torque-transfer component engineered specifically for the WG 100 and WG 110 transmission series. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages power flow between the input shaft and the intermediate housing. The SKU 4651.153.004 is designed to withstand high cyclic loads and thermal stress, ensuring precise shift timing and consistent power delivery in heavy-duty industrial applications. When paired with a robust TRANSMISSION HOUSING, this clutch maintains alignment and reduces wear on adjacent components.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn clutch plates cause hesitation or abrupt shifts, especially under load, making the transmission feel unresponsive.
• Transmission oil overheating: Slipping clutch packs generate excess friction, raising fluid temperatures beyond normal operating ranges and triggering warning lights.
• Intermittent loss of drive in forward gears: A failing 4651.153.004 clutch may cause the WG 100 to momentarily lose power during acceleration, often mistaken for pump issues.
• Metallic debris in the oil pan: Friction material shedding from the clutch disc contaminates the fluid, visible as glitter or sludge during routine maintenance.

Technical Specifications

Compatibility

This clutch is primarily designed for the ZF WG 100 and WG 110 series transmissions, commonly found in municipal trucks, fire apparatus, and construction equipment. It is also compatible with the WG 180 and WG 200 models when used with the correct HOUSING adapter. For proper sealing, always replace the O-RING during installation. The 4651.153.004 clutch works in conjunction with the HOUSING to maintain concentricity and prevent fluid bypass.
