ZF 2098.209.011 BEVEL GEAR SET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2098.209.011 BEVEL GEAR SET is a precision-engineered OEM genuine component designed for the final drive assembly of ZF WG100, WG130, and WG131 powershift transmissions. This matched set of spiral bevel gears transfers rotational power from the transmission output shaft to the axle differential at a specific reduction ratio, ensuring smooth torque delivery under heavy load conditions. The SKU 2098.209.011 is manufactured to exacting ZF tolerances for backlash and tooth contact pattern, making it a direct replacement for worn or damaged gear sets. When installed correctly, this bevel gear set works in concert with the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS. to form the core of the driveline.

Symptoms of Failure

• Whining or howling noise from the transmission during acceleration or deceleration: This indicates worn gear teeth or incorrect backlash, often caused by fatigue or contamination in the lubricant.
• Vibration in the driveline at specific vehicle speeds: A failing bevel gear set can produce cyclic vibrations that are felt through the chassis, especially when turning or under load.
• Metal debris or glitter in the transmission oil: Flaking or pitting on the gear tooth surfaces will shed metallic particles into the sump, which can be detected during oil changes or filter inspections.
• Intermittent gear slipping or loss of power transfer: As the gear teeth wear unevenly, the mesh becomes loose, leading to momentary disengagement under high torque conditions.

Technical Specifications

Compatibility

This bevel gear set is specifically engineered for ZF WG-series powershift transmissions. It is a direct fit for the following models:

• ZF WG100
• ZF WG130
• ZF WG131

While primarily designed for these three models, the 2098.209.011 may also be compatible with certain variants of the WG180 and WG200 series where the final drive ratio matches. Always verify the tooth count and housing dimensions before installation. The gear set mounts inside the 2098117002: HOUSING and is secured using the 0636103300: STUD and 0637101164: HEXAGON NUT hardware. For complete axle assembly, pair with the 2098301052: REAR AXLE HOUS.
