ZF 4651.151.005 CLUTCH for WG 100/WG 110 | OEM Genuine Part

Overview

The ZF 4651.151.005 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. Designed to withstand high cyclic loads, the 4651.151.005 clutch pack ensures smooth gear shifts and reliable power delivery under heavy-duty industrial conditions. When paired with the 4651101007 TRANSMISSION HOUSING, this clutch maintains precise alignment within the drivetrain, reducing wear on adjacent components.

Symptoms of Failure

• Delayed or harsh engagement: A worn 4651.151.005 clutch often causes hesitation when shifting from neutral to drive, or produces a noticeable jolt during gear changes.
• Slipping under load: If the clutch disc friction material degrades, the transmission may slip during acceleration, especially when climbing grades or carrying heavy payloads.
• Contaminated transmission fluid: Friction material shedding from the clutch can turn the oil dark or produce a burnt smell, often accompanied by metallic particles in the sump.
• Intermittent loss of power: A failing clutch may cause sudden power drops at specific RPM ranges, indicating partial disengagement of the gear set.

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 medium-duty construction vehicles. It also fits select variants of the WG 180 and WG 200 series when used with the appropriate 4651301029 HOUSING adapter. For proper sealing during installation, always replace the 0634303928 O-RING and verify alignment with the 4651301024 HOUSING to prevent fluid bypass.
