ZF 4108.301.474 INPUT SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4108.301.474 INPUT SHAFT is a critical torque-transmitting component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part transfers rotational power from the engine directly into the gear train, ensuring precise engagement and smooth power flow. The SKU 4108.301.474 is machined to exacting tolerances to interface seamlessly with the 4108101062 HOUSING and the 4108201297 HOUSING, forming the primary structural assembly. Proper alignment of this shaft is essential for maintaining gear mesh integrity and preventing premature wear across the drivetrain.

Symptoms of Failure

When the 4108.301.474 INPUT SHAFT begins to degrade, operators often notice distinct operational issues. Gear slipping under load is a primary indicator, as worn splines fail to maintain positive engagement. Vibration during acceleration typically arises from bearing surface deterioration on the shaft journal. Oil leaks at the front seal area occur when the shaft surface becomes scored, compromising the 0501325470 SEALING RING. Additionally, difficulty shifting into gear can signal that the input shaft pilot bearing has worn, creating misalignment that strains the entire clutch assembly.

Technical Specifications

Compatibility

This input shaft is specifically designed for the ZF WG100, WG130, and WG131 transmission families. It is also compatible with select variants of the WG180 and WG200 series where the input spline configuration matches. Always verify the spline count and pilot bearing diameter against your transmission’s serial number. For accurate fluid level monitoring during installation, pair this shaft with the 0501215601 OIL LEVEL GAGE to ensure proper lubrication of the front bearing cluster.
