ZF 4143.103.040 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.040 OUTPUT is a critical OEM genuine component designed for the output section of ZF’s heavy-duty transmission assemblies. This part serves as the primary interface between the transmission and the driveline, ensuring precise torque transfer and rotational stability. Positioned at the rear of the gearbox housing, the 4143.103.040 OUTPUT works in concert with the 4143101030: HOUSING and the 4143301055: HOUSING to maintain structural integrity under high load conditions. The SKU 4143.103.040 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in HL 100 and HL 270 series transmissions.

Symptoms of Failure

When the ZF 4143.103.040 OUTPUT begins to degrade, operators often notice three distinct failure indicators. First, oil seepage around the output flange occurs as the sealing surfaces wear, leading to gradual fluid loss. Second, gear slipping under heavy acceleration becomes apparent when the output component cannot maintain proper engagement with the planetary set. Third, vibrations at highway speeds indicate bearing surface wear within the output assembly. Fourth, erratic shifting patterns may develop as the output sensor ring misaligns, triggering fault codes in electronic controls.

Technical Specifications

Compatibility

This OEM genuine output component is engineered for ZF’s HL 100 and HL 270 series transmissions. It also fits select WG180 and WG200 models produced between 2005 and 2018. The 4143.103.040 OUTPUT integrates with the 4143298040: CASE and requires the 0631329135: SPRING PIN for proper alignment during installation. Always verify your transmission serial number before ordering.
