ZF 4143.103.038 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.038 OUTPUT is a critical OEM genuine component engineered for the HL 100 Series and HL 270 Series transmission families. This output assembly serves as the primary interface between the transmission and the driveline, transferring rotational force from the final gear set to the vehicle’s axle. As a precision-machined part, it ensures proper alignment and torque distribution under heavy loads. The SKU 4143.103.038 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units in industrial and off-highway applications.

Symptoms of Failure

• Output shaft oil leaks: When the seal surface on the 4143.103.038 wears, transmission fluid seeps past the housing, leading to low oil levels and potential gear damage.
• Driveline vibration or shudder: A worn output assembly causes misalignment, resulting in noticeable shaking during acceleration or at cruising speeds.
• Gear slipping or delayed engagement: Internal wear within the output section prevents proper torque transfer, causing the transmission to slip out of gear under load.
• Metallic grinding noises: Bearing failure inside the output unit produces a distinct grinding sound, indicating imminent component failure.

Technical Specifications

Compatibility

This OEM genuine output is designed for ZF transmissions in the HL 100 Series and HL 270 Series. It is commonly found in models such as the WG180, WG200, and WG210. The 4143.103.038 also integrates with earlier HL 90 variants and certain 4WG-310 configurations. Always verify your transmission serial number before ordering.

During installation, this output works in conjunction with the 4143101030: HOUSING and the 4143301055: HOUSING to create a sealed assembly. The 4143298040: CASE provides structural support, while the 0631329135: SPRING PIN secures the output shaft in place. For a complete rebuild, consider replacing the sealing cap and cap screw simultaneously.
