ZF 4642.103.427 OUTPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.103.427 OUTPUT for WG150 is a critical drivetrain component engineered to transfer rotational force from the transmission’s planetary gearset to the output flange. Positioned at the rear of the WG 150 series housing, this OEM genuine part ensures precise torque delivery under heavy-duty industrial loads. The SKU 4642.103.427 is machined to exact ZF tolerances, making it a direct replacement for worn or damaged output shafts. When paired with a robust TRANSMISSION HOUSING (4642101109), this component maintains alignment and reduces vibration in demanding applications.

Symptoms of Failure

• Oil seepage at the rear seal: A worn 4642.103.427 output shaft often damages the lip seal, leading to visible transmission fluid leaks around the output flange.
• Gear slipping under load: Excessive play in the output splines causes intermittent power loss, especially during acceleration or uphill operation.
• Metallic grinding noises: Bearing surface degradation on the output shaft produces a distinct whining or grinding sound, indicating imminent failure.
• Driveline vibration: A bent or worn output shaft creates rhythmic shaking at highway speeds, often misdiagnosed as a universal joint issue.

Technical Specifications

Compatibility

This output shaft is specifically designed for the ZF WG 150 series, but it also fits select variants of the WG180 and WG200 transmissions when used with the correct TRANSMISSION HOUSING (4642301205). Always verify the spline count and pilot bearing diameter against your existing unit. For accurate identification, the TYPE PLATE (0730365125) provides the exact transmission model code. Secure the assembly using a GROOVED STUD (0631311009) to prevent axial movement.
