Overview
The ZF 4642.103.414 OUTPUT for WG150 is a critical driveline component engineered to transfer rotational force from the transmission’s planetary gearset to the output shaft flange. Positioned at the rear of the gearbox housing, this OEM genuine part ensures precise torque delivery and minimal power loss during heavy-duty operations. The SKU 4642.103.414 is specifically designed for the WG 150 Series, providing a direct replacement that maintains factory tolerances and load-bearing capacity. When installed alongside a TRANSMISSION HOUSING (4642101047), this output assembly forms a sealed, high-strength interface that withstands extreme axial and radial forces in construction and agricultural machinery.
Symptoms of Failure
- Oil leaks at the rear seal: Worn output shafts allow transmission fluid to escape past the seal, leaving puddles under the vehicle and causing low fluid levels.
- Gear slipping under load: A damaged output spline or bearing surface prevents consistent torque transfer, resulting in intermittent power loss during acceleration or climbing.
- Vibration or driveline shudder: Excessive play in the output assembly creates harmonic vibrations that worsen at highway speeds, often accompanied by a rhythmic clunking noise.
- Difficulty engaging park or neutral: Internal wear on the output gear teeth can interfere with the parking pawl mechanism, making gear selection erratic or noisy.

Compatibility
This output shaft is engineered for the ZF WG 150 Series transmission family. It is directly compatible with the WG150, WG151, and WG152 models found in wheel loaders, telehandlers, and industrial forklifts. While primarily designed for the WG150, the 4642.103.414 may also fit select WG180 and WG200 variants when used with the correct TRANSMISSION HOUSING (4642301207). Always verify spline engagement and housing bore dimensions before installation. The part integrates with the TYPE PLATE (0730365067) for proper identification and is secured using a GROOVED STUD (0631311009) to prevent axial movement.
