ZF 4143.103.005 OUTPUT | OEM Genuine Part

Overview

The ZF 4143.103.005 OUTPUT is a precision-engineered OEM genuine component designed for the output section of ZF’s HL 100 and HL 270 series transmissions. This part serves as the critical interface between the transmission housing and the driveline, ensuring torque is transferred smoothly from the gearset to the output flange. As a factory-specified replacement, the SKU 4143.103.005 guarantees exact fitment and durability under heavy-duty industrial loads. It works in concert with the 4143101009: HOUSING and 4143301025: HOUSING to maintain structural integrity within the transmission assembly.

Symptoms of Failure

When the ZF 4143.103.005 OUTPUT begins to degrade, operators will notice distinct performance issues. Oil seepage around the output shaft seal is the most common early indicator, often leaving puddles under parked equipment. Gear slipping under load occurs as the output component loses its precise engagement with mating parts. A persistent whining or grinding noise from the transmission rear section signals bearing surface wear. Additionally, vibration through the driveline during acceleration suggests the output assembly has developed excessive play, requiring immediate replacement to prevent cascading damage.

Technical Specifications

Compatibility

This OEM genuine output component is engineered for ZF transmissions in the HL 100 and HL 270 series. It is directly compatible with models including the WG180, WG200, WG210, and WG250 series, where it replaces the original output shaft assembly. The part also fits select Ecomat 4HP and 6HP variants that share the same output architecture. For a complete rebuild, pair this output with the 0634313603: O-RING and 4475280018: SCREW PLUG to ensure a leak-free seal and secure fastening.
