ZF 4108.301.468 INPUT SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4108.301.468 INPUT SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 series transmissions. As the primary interface between the engine clutch and the gearset, this OEM genuine shaft transmits rotational force directly into the planetary assembly. The SKU 4108.301.468 is precision-machined to maintain concentricity and spline engagement, ensuring smooth power delivery under heavy-duty industrial loads. It sits at the front of the main housing, interfacing directly with the 4108101171: HOUSING and the 4108102067: INPUT assembly.

Symptoms of Failure

• Gear slipping under load: Worn splines on the input shaft cause intermittent disengagement, especially during torque peaks in WG130 units.
• Transmission whining or grinding noise: Bearing surface wear on the shaft produces a high-pitched metallic sound that intensifies with RPM.
• Oil contamination from metal debris: Flaking or pitting on the shaft surface introduces ferrous particles into the lubricant, often detected during routine oil level checks with the 0501215601: OIL LEVEL GAGE.
• Vibration during engagement: A bent or fatigued input shaft creates harmonic vibrations that resonate through the 0501325470: SEALING RING area, leading to premature seal failure.

Technical Specifications

Compatibility

This input shaft is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is not compatible with WG180 or WG200 variants without additional adapter modifications. For proper installation, always verify the spline count and pilot bearing fitment. The shaft works in conjunction with the 0730365280: TYPE PLATE to confirm transmission model identification.
