Overview
The ZF 2095.346.088 SPUR GEAR is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This gear is located within the countershaft assembly, where it directly engages with the differential to transfer rotational force from the input shaft to the output drive. As a critical element in the power flow path, it ensures smooth torque delivery and maintains gear mesh alignment under heavy loads. The SKU 2095.346.088 is factory-verified to meet ZF’s exacting tolerances for hardness and tooth profile, making it a direct replacement for worn units in commercial vehicle drivelines.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn spur gear produces a distinct high-pitched whine that intensifies under load, often mistaken for differential noise. This indicates tooth surface pitting or misalignment.
- Intermittent gear slipping under heavy torque: When the gear teeth lose their flank profile, the transmission may momentarily lose engagement, causing a brief loss of power during hill climbs or loaded starts.
- Metallic debris in transmission oil: Flakes or small chips found during routine oil changes signal advanced wear of the spur gear teeth, often accompanied by scoring on the mating 2095109020 DIFFERENTIAL.
- Vibration in the driveline at specific RPMs: Uneven tooth wear creates harmonic vibrations that can be felt through the chassis, particularly between 1500-2000 RPM.

Compatibility
This spur gear is specifically designed for the ZF WG100, WG130, and WG131 transmission models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct 2095209037 DIFFERENTIAL and 2095309059 DIFF.HOUSING. For proper installation, always pair this gear with a new 0750117075 TAPER ROLLER BEARING to ensure correct axial preload and gear mesh alignment. Verify your transmission serial number against ZF’s application guide before ordering.
