ZF 2052.309.173 AXLE BEVEL GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2052.309.173 AXLE BEVEL GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational power from the driveshaft to the axle differential at a precise angle, enabling smooth torque distribution within the final drive assembly. As a bevel gear, it directly meshes with the ring gear to convert longitudinal input into lateral wheel movement. The SKU 2052.309.173 is manufactured to ZF’s exacting tolerances, ensuring minimal backlash and optimal load-bearing capacity under heavy-duty industrial conditions. This gear sits within the rear housing section, adjacent to the 2094101012: TRANSMISSION HOUSING, which provides structural support and lubrication channels for the gearset.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
• Vibration in the driveline at low speeds: Excessive play between the bevel gear and mating ring gear causes rhythmic shuddering, often felt through the chassis.
• Metallic debris in transmission fluid: Flaking or pitting on the gear surface contaminates the oil, visible as silver or copper-colored particles during drain intervals.
• Intermittent loss of drive or slipping: Severely worn teeth can skip under torque, leading to momentary power interruption or harsh engagement.

Technical Specifications

Compatibility

This bevel gear is specifically designed for ZF WG100, WG130, and WG131 transmissions, commonly found in agricultural tractors, construction loaders, and industrial material handlers. It also fits select variants of the WG180 and WG200 series when used with the appropriate 2094301036: HOUSING adapter. For proper installation, ensure the mating 2094298057: HOUSING is free of cracks and the 2094301071: COVER is torqued to factory specifications. Always replace the shaft seal and O-ring during gear replacement to prevent contamination.
