ZF 4143.103.424 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.424 OUTPUT is a critical OEM genuine component engineered for the HL 100 and HL 270 series transmission assemblies. This part functions as the primary output shaft hub, transferring rotational force from the planetary gear set to the driveline. Positioned at the rear of the transmission housing, it interfaces directly with the 4143101030: HOUSING to ensure precise alignment and torque distribution. The SKU 4143.103.424 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit without modification. This output component is essential for maintaining drivetrain integrity in heavy-duty industrial applications, where even minor deviations can lead to system inefficiency.

Symptoms of Failure

• Oil leaks at the rear seal interface: A worn 4143.103.424 output hub often causes fluid seepage past the seal, leading to low transmission fluid levels and potential overheating.
• Gear slipping under load: When this output component loses its spline engagement, operators may experience intermittent power loss or delayed engagement during acceleration.
• Abnormal vibration or noise: Excessive play in the output shaft bearing seat produces a distinct whining or clunking sound, especially during deceleration or turns.
• Driveline misalignment: A failing output hub can cause the attached 0631329135: SPRING PIN to shear, resulting in erratic shifting and increased wear on adjacent components.

Technical Specifications

Compatibility

This ZF 4143.103.424 output component is designed for use in the HL 100 and HL 270 series transmissions, which are commonly found in forklifts, telehandlers, and industrial loaders. It also fits select WG180 and WG200 models when paired with the correct 4143301055: HOUSING. For applications requiring a complete rebuild, the 4143298040: CASE must be inspected for cracks or wear before installation. Always verify serial numbers against ZF’s compatibility charts to ensure proper fitment.
