ZF 2094.322.054 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.322.054 SPUR GEAR is a precision-machined helical gear designed for the auxiliary drive train within ZF WG100, WG130, and WG131 series transmissions. This OEM genuine part transmits rotational torque from the input shaft to the intermediate shaft, ensuring smooth power flow during gear engagement. The SKU 2094.322.054 sits directly within the gear cluster assembly, meshing with the countershaft to maintain synchronized speed ratios. When installed alongside the 2094009020: T 7336 L thrust washer, this spur gear maintains axial alignment under heavy load conditions.

Symptoms of Failure

• Whining or grinding noise during acceleration – Worn gear teeth produce a high-pitched metallic sound, especially when shifting under load in WG100 transmissions.
• Intermittent gear slipping in higher ranges – A damaged spur gear causes the transmission to momentarily lose torque transfer, resulting in a “skip” sensation during highway cruising.
• Metal particles in transmission fluid – Flaking or pitting on the gear surface contaminates the oil, visible as glitter-like debris during routine drain intervals.
• Vibration through the gearshift lever – Uneven tooth wear creates harmonic imbalance, felt as a persistent shudder in the cab at specific RPM ranges.

Technical Specifications

Compatibility

This spur gear is engineered exclusively for ZF WG-series mechanical transmissions. Verified fitment includes the WG100, WG130, and WG131 models, commonly found in medium-duty trucks and agricultural machinery. The gear interfaces directly with the 2094101017: TRANSMISSION HOUSING and the 2094298054: HOUSING assembly. For proper sealing, ensure the 2094301069: HOUSING cover is torqued to factory specifications during reinstallation.
