ZF 2098.346.001 DOUBLE GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2098.346.001 DOUBLE GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as an intermediate gear cluster, transferring torque between the input shaft and the main drive train within the gearbox assembly. The SKU 2098.346.001 is precision-machined to ZF’s original specifications, ensuring exact meshing with adjacent gears and shafts. It sits directly within the transmission housing, where it must maintain strict alignment to prevent premature wear on surrounding components like the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS..

Symptoms of Failure

• Whining or grinding noise during gear engagement: A worn double gear produces a distinct metallic whine, especially under load or during deceleration, indicating tooth surface degradation.
• Intermittent gear slipping under torque: As the gear teeth lose their profile, the transmission may momentarily lose power transfer, causing a “skip” sensation when accelerating.
• Metallic debris in transmission fluid: Flaking or pitting on the gear faces introduces fine metal particles into the oil, often visible during routine fluid changes.
• Vibration through the shift lever or chassis: Uneven wear on the double gear creates rotational imbalance, transmitting vibration through the 0636103300: STUD and 0637101164: HEXAGON NUT fasteners.

Technical Specifications

Compatibility

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

• ZF WG100 (all sub-variants)
• ZF WG130 (standard and heavy-duty configurations)
• ZF WG131 (with integrated retarder option)

It may also fit select WG180 and WG200 series units when used in conjunction with the correct 2098117002: HOUSING and 2098301052: REAR AXLE HOUS. Always verify spline count and shaft diameter before installation.
