ZF 2095.303.032 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.032 GEAR is a precision-machined helical gear designed for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmission assemblies. This OEM genuine part transfers rotational torque from the input shaft to the differential carrier, directly influencing the gear ratio and load distribution in heavy-duty commercial drivelines. The SKU 2095.303.032 is a factory-spec component, ensuring exact tooth geometry and surface hardness for minimal backlash. When installed alongside a 5838109007: DIFFERENTIAL, this gear synchronizes power flow to the output shafts, reducing vibration under high-torque conditions.

Symptoms of Failure

• Whining or howling noise during deceleration — Worn teeth on the 2095.303.032 gear create irregular contact patterns, producing a distinct metallic whine that intensifies when the vehicle coasts downhill.
• Intermittent gear slippage under load — As the gear’s flank surface degrades, the transmission may momentarily lose torque transfer when climbing grades or hauling maximum payloads, often accompanied by a brief RPM spike.
• Metal particles in transmission fluid — Flaking or spalling from the gear’s case-hardened layer contaminates the oil, visible as silver or bronze glitter on the dipstick or during a drain interval.
• Hard shifting between forward and reverse — Excessive wear on the gear’s spline engagement area causes delayed or abrupt engagement, particularly when transitioning from neutral to drive.

Technical Specifications

Compatibility

This gear is engineered for the ZF WG100, WG130, and WG131 series transmissions, which are commonly found in municipal trucks, fire apparatus, and medium-duty construction vehicles. It is also compatible with the ZF WG180 and WG200 models when used in auxiliary drive positions, though confirmation of shaft spline count is recommended. For complete differential rebuilds, pair this gear with a 2095209019: DIFFERENTIAL and a 0750117075: TAPER ROLLER BEARING to ensure proper preload and axial alignment. The 0631329086: SPRING PIN is also required for securing the gear to its shaft in most WG-series applications.
