ZF 4108.102.046 INPUT | OEM Genuine Part

Overview

The ZF 4108.102.046 INPUT is a critical OEM genuine component engineered to transfer engine torque directly into the planetary gear set of heavy-duty construction machinery transmissions. As the primary power entry point, this input shaft assembly ensures smooth engagement and reliable power flow under extreme load conditions. The SKU 4108.102.046 is precision-machined to factory tolerances, guaranteeing a direct fit without modification. This part interfaces directly with the 4108101086: HOUSING and the 4108201287: HOUSING to form the sealed driveline assembly, while the 0501215601: OIL LEVEL GAGE provides essential fluid monitoring for the input section.

Symptoms of Failure

• Transmission input shaft oil leaks: Worn seals on the 4108.102.046 allow hydraulic fluid to escape, often pooling beneath the bell housing during operation.
• Hard shifting or gear slippage under load: A damaged input shaft can cause intermittent power loss, especially when climbing grades or moving heavy earth.
• Unusual whining or grinding noises from the front of the transmission: Bearing wear or spline degradation on the input assembly produces metallic sounds that intensify with engine RPM.
• Vibration through the driveline during acceleration: Bent or fatigued input shafts create harmonic oscillations felt in the operator cab.

Technical Specifications

Compatibility

This OEM genuine input component is designed for integration into ZF WG-series powershift transmissions commonly found in wheel loaders, graders, and telescopic handlers. It is a direct replacement for the following models: WG180, WG200, WG210, and WG250. The 4108.102.046 also fits select 4WG-200 and 6WG-200 variants used in construction machinery from Volvo, Liebherr, and Caterpillar. Always verify the existing 4108301293: BEARING COVER condition during replacement to ensure proper preload on the input shaft assembly.
