ZF 2095.303.022 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.022 GEAR is a precision-machined helical gear designed for the auxiliary drive and power take-off (PTO) train within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational torque from the input shaft to the differential assembly, ensuring synchronized speed regulation during load shifts. The SKU 2095.303.022 sits directly on the countershaft cluster, meshing with the main drive gear to distribute power to the wheel ends. When this gear wears, it compromises the entire drivetrain’s torque curve, leading to operational inefficiencies in heavy-duty commercial vehicles.

Symptoms of Failure

• Whining or grinding noise during acceleration: A worn 2095.303.022 gear produces a high-pitched whine under load, often mistaken for bearing failure. This noise intensifies when the transmission is in lower gears.
• Intermittent gear slipping under heavy torque: As the gear teeth lose their profile, the transmission may momentarily lose engagement, causing a sudden RPM spike without corresponding vehicle speed increase.
• Metal particles in transmission fluid: Flaking or pitting on the gear surface sheds ferrous debris into the oil, which can clog the filter and damage downstream components like the 5838109007: DIFFERENTIAL.
• Hard shifting or delayed engagement: Worn gear teeth create backlash that prevents smooth synchronization, requiring excessive force to engage gears, particularly in cold-start conditions.

Technical Specifications

Compatibility

This gear is engineered for ZF WG-series transmissions with a modular auxiliary drive configuration. It is directly compatible with the following models: WG100, WG130, WG131, and WG180 (when fitted with the optional PTO housing). For WG200 and WG250 variants, verify the countershaft spline count before installation. The gear interfaces with the 0750117075: TAPER ROLLER BEARING on the output shaft and aligns with the 2095209019: DIFFERENTIAL carrier. A 0631329086: SPRING PIN secures the gear to the shaft, preventing axial movement during high-RPM operation.
