ZF 2094.304.062 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.304.062 GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 2094.304.062, sits within the intermediate shaft assembly, where it meshes directly with the main drive gear to facilitate torque transfer from the engine to the output shaft. Precision-ground teeth ensure minimal backlash and quiet operation under heavy loads. When replacing this gear, it is common to inspect the surrounding 2094101012: TRANSMISSION HOUSING for wear, as housing distortion can accelerate gear tooth degradation.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth create excessive clearance, producing a distinct metallic whine that intensifies under load.
• Intermittent gear slipping under torque: As the gear profile wears, the transmission may momentarily lose engagement, causing a sudden RPM surge without corresponding speed increase.
• Metallic debris in transmission fluid: Flaking or pitting on the gear surface contaminates the oil with fine metal particles, often visible during routine fluid changes.
• Vibration through the shift lever: Uneven tooth wear induces harmonic vibrations that transmit through the driveline, felt as a constant buzz in the operator station.

Technical Specifications

Compatibility

This gear is specifically designed for ZF WG-series powershift transmissions. Verified compatible models include:

• ZF WG100
• ZF WG130
• ZF WG131
• ZF WG180 (with adapter shaft)
• ZF WG200 (limited to early production runs)

During installation, always replace the 2094301036: HOUSING and 2094298057: HOUSING if they show scoring or cracks. The 2094301071: COVER must also be torqued to factory specifications to maintain proper bearing preload.
