ZF 4642.355.001 DRIVER for WG150 | OEM Genuine Part

Overview

The ZF 4642.355.001 DRIVER is a critical rotational component engineered specifically for the WG150 series transmission. This OEM genuine part functions as the primary torque-transfer interface within the clutch pack assembly, converting hydraulic pressure into precise mechanical engagement. Positioned directly on the main shaft, the DRIVER ensures synchronized gear shifts and reliable power delivery under heavy-duty industrial loads. The SKU 4642.355.001 is manufactured to ZF’s exacting tolerances, making it an essential replacement for maintaining transmission integrity. When paired with a robust TRANSMISSION HOUSING (4642101047) or a TRANSMISSION HOUSING (4642301207), this DRIVER guarantees optimal alignment and longevity in demanding applications.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn 4642.355.001 DRIVER often causes noticeable hesitation or clunking when shifting between forward and reverse, particularly under load.
• Transmission fluid contamination: As the DRIVER surface degrades, metallic particles can enter the oil, leading to accelerated wear on adjacent components like the GROOVED STUD (0631311009).
• Intermittent power loss during operation: Slipping or incomplete torque transfer results in reduced wheel speed despite engine RPM increases, a classic sign of DRIVER fatigue.
• Audible grinding or whining noises: Excessive clearance from a failing DRIVER produces distinct metallic sounds, especially during low-speed maneuvers or hill climbs.

Technical Specifications

Compatibility

While the 4642.355.001 DRIVER is primarily designed for the WG150 series, its spline geometry and pressure plate interface make it compatible with several ZF transmission models. Verified applications include the WG180, WG200, and WG210 series, provided the transmission uses a 38mm main shaft. For proper installation, always verify the condition of the TYPE PLATE (0730365067) to confirm model revision. The DRIVER also integrates seamlessly with the SHIFT SYSTEM (4644106300) and COVER PLATE (4644306500) in these assemblies.
