ZF 4642.302.162 OUTPUT SHAFT for WG150 | OEM Genuine Part

Overview

The ZF 4642.302.162 OUTPUT SHAFT is a critical torque-transfer component engineered specifically for the WG 150 series transmission family. This OEM genuine part transmits rotational power from the planetary gearset to the driveline flange, ensuring smooth energy delivery under heavy-duty industrial loads. The SKU 4642.302.162 sits at the rear of the main transmission housing, directly interfacing with the output flange and the TRANSMISSION HOUSING assembly. Precision-machined from high-strength alloy steel, this shaft maintains concentricity and axial alignment to prevent vibration and premature bearing wear. As a factory-spec replacement, it restores original performance characteristics and extends the service life of your ZF drivetrain.

Symptoms of Failure

• Oil leaks near the rear seal area – Worn splines or a scored shaft surface can damage the output seal, causing transmission fluid to weep or drip, often visible around the flange connection.
• Gear slipping under load – When the output shaft splines wear or develop torsional fatigue, power transfer becomes intermittent, leading to hesitation or slipping during acceleration or hill climbs.
• Vibration or driveline shudder – A bent or cracked output shaft creates rotational imbalance, producing low-frequency vibrations that intensify at specific RPM ranges and can be felt through the chassis.
• Unusual metallic grinding noises – Worn bearing journals or fretting on the shaft surface generate audible grinding or clicking sounds, especially during gear engagement or coasting.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 150 series, but its spline geometry and bearing dimensions also suit the WG 180 and WG 200 series transmissions used in medium-duty trucks, construction loaders, and agricultural tractors. It directly replaces the original shaft in models with a 14-spline output flange. For proper fitment, verify that your transmission housing matches the TRANSMISSION HOUSING variant used in your specific assembly. Always cross-reference the TYPE PLATE on your unit to confirm the exact series designation before ordering.
