ZF 4108.102.072 INPUT | OEM Genuine Part

Overview

The ZF 4108.102.072 INPUT is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This critical part serves as the primary power entry point, transferring torque from the engine directly into the transmission assembly. Located at the front of the gearbox housing, the input unit ensures smooth engagement and reliable power flow under extreme loads. The SKU 4108.102.072 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in demanding environments such as excavators, wheel loaders, and graders. When paired with the INPUT SHAFT, this component forms the backbone of the drivetrain’s initial power transfer stage.

Symptoms of Failure

When the ZF 4108.102.072 INPUT begins to wear, operators will notice distinct performance issues. Transmission input shaft oil leaks often appear as fluid seeping from the front bell housing area, indicating seal degradation around the input assembly. Gear slipping under load becomes apparent during acceleration or climbing, as the worn input cannot maintain proper torque transfer. Abnormal grinding or whining noises from the transmission front section signal bearing wear within the input unit. Additionally, difficulty engaging gears or a delayed shift response frequently points to a failing input component that requires immediate replacement to prevent cascading damage to the HOUSING.

Technical Specifications

Compatibility

This OEM genuine input component is engineered for use in ZF WG series transmissions commonly found in construction machinery. The 4108.102.072 is directly compatible with the ZF WG180 and ZF WG200 transmission models, which power equipment from manufacturers like Liebherr, Caterpillar, and Volvo. It also fits select variants of the ZF WG150 and WG210 series. For proper installation, always replace the GASKET and verify the TYPE PLATE matches your transmission model to ensure correct specification alignment.
