ZF 4642.302.138 OUTPUT SHAFT for WG150 | OEM Genuine Part

Overview

The ZF 4642.302.138 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 150 series transmission. This OEM genuine part transfers rotational torque from the planetary gear set to the vehicle’s drive shaft, ensuring smooth power delivery under heavy loads. Positioned at the rear of the transmission housing, the output shaft interfaces directly with the TRANSMISSION HOUSING (4642101047) and the TRANSMISSION HOUSING (4642301207) to maintain precise alignment. The SKU 4642.302.138 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged shafts in commercial and industrial applications.

Symptoms of Failure

• Oil leaks at the rear seal: A worn output shaft bearing surface can damage the seal, causing transmission fluid to drip near the driveline connection.
• Vibration during gear engagement: Excessive play in the shaft splines or bearing journals leads to driveline shudder, especially under load or at highway speeds.
• Gear slipping or delayed engagement: When the output shaft splines wear, torque transfer becomes inconsistent, resulting in erratic shifting or complete loss of drive.
• Metallic debris in the oil pan: Flaking or pitting on the shaft surface introduces metal particles into the transmission fluid, often accompanied by whining noises.

Technical Specifications

Compatibility

This output shaft is primarily designed for the ZF WG 150 series transmission. Based on its spline geometry and bearing dimensions, it is also compatible with the WG 180 and WG 200 models that share the same rear housing interface. Always verify fitment by cross-referencing the TYPE PLATE (0730365067) on your transmission, as variations exist between early and late production units. The shaft is secured using the GROOVED STUD (0631311009) to prevent axial movement during operation.
