ZF 2095.322.004 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.322.004 SPUR GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the gear train assembly, where it meshes directly with the differential ring gear to transmit rotational force from the input shaft to the axle output. Designed to handle high torque loads in heavy-duty commercial vehicles, the 2095.322.004 spur gear ensures precise gear engagement and minimal backlash. For optimal drivetrain performance, this gear is often replaced alongside the 2095109015 DIFFERENTIAL and the 2095209037 DIFFERENTIAL to maintain synchronized wear patterns.

Symptoms of Failure

• Whining or grinding noise during acceleration: Worn gear teeth produce a high-pitched whine or metallic grinding sound, especially under load. This is a classic sign of pitting or chipping on the spur gear face.
• Intermittent gear slipping or loss of drive: When the spur gear teeth become excessively worn, the transmission may momentarily lose torque transfer, causing the vehicle to hesitate or slip during gear changes.
• Metal debris in transmission fluid: Flakes or particles found during oil changes indicate advanced gear wear. This debris can also damage the 0750117075 TAPER ROLLER BEARING and other rotating components.
• Vibration through the driveline: Uneven tooth wear creates imbalance, transmitting vibration to the 2095309059 DIFF.HOUSING and the vehicle chassis at highway speeds.

Technical Specifications

Compatibility

This spur gear is specifically designed for the ZF WG100, WG130, and WG131 transmission models. These units are commonly found in medium-duty trucks, buses, and agricultural machinery. While the gear is not directly compatible with the WG180 or WG200 series due to different tooth counts and shaft diameters, it may be used in certain WG120 variants with the same gear ratio. Always verify the existing gear’s tooth profile and bore diameter before installation. For complete drivetrain rebuilds, consider pairing this gear with the 4482360002 AXLE BEVEL GEAR and 4482360001 DIFFERENTIAL BEVEL GEAR for matched wear sets.
