ZF 4108.103.106 OUTPUT | OEM Genuine Part

Overview

The ZF 4108.103.106 OUTPUT is a critical OEM genuine component engineered for the rear power take-off (PTO) assembly in heavy-duty construction machinery transmissions. This output shaft transfers rotational force from the transmission’s planetary gearset to the driveline, enabling reliable torque delivery under extreme loads. As a factory-specified replacement, the SKU 4108.103.106 ensures precise fitment and metallurgical integrity, preventing premature wear in demanding applications like wheel loaders and graders. When paired with the 4108101108: HOUSING, this part forms the backbone of the output module, while the 4108306172: GASKET seals the interface to prevent contamination.

Symptoms of Failure

Operators encountering output shaft oil leaks around the rear seal area should inspect the 4108.103.106 for surface scoring or pitting. A second common failure sign is gear slipping under load, particularly during uphill travel or when engaging the PTO, indicating worn splines or bearing journals. Third, vibration or whining noise from the transmission housing at highway speeds often points to a bent or unbalanced output shaft. Finally, difficulty shifting into reverse or low gear may arise if the output shaft’s alignment with the 4108301436: INPUT SHAFT is compromised due to fatigue.

Technical Specifications

Compatibility

This OEM genuine output shaft is designed for ZF WG series powershift transmissions commonly found in construction machinery. It directly fits the WG180, WG200, and WG220 models, as well as the WG240 heavy-duty variant. The part also cross-references with select ZF 4WG-200 and ZF 6WG-250 transmissions used in articulated dump trucks and crawler dozers. Always verify the 0730365280: TYPE PLATE on your transmission housing to confirm compatibility before installation.
