ZF 2095.322.016 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.322.016 SPUR GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part (SKU: 2095.322.016) sits within the gear train assembly, directly meshing with the differential system to convert rotational input into precise torque output. It ensures smooth engagement between the main shaft and the differential housing, reducing vibration and maintaining consistent gear ratios under heavy loads. As a genuine ZF component, it guarantees exact fitment and metallurgical integrity, preventing premature wear in adjacent assemblies such as the 2095109015 DIFFERENTIAL and the 2095209037 DIFFERENTIAL.

Symptoms of Failure

• Whining or grinding noise during acceleration: A worn spur gear produces a distinct high-pitched whine or metallic grinding, especially when shifting from low to high torque. This indicates tooth surface degradation or pitting.
• Intermittent gear slipping under load: When the spur gear loses tooth profile integrity, the transmission may momentarily slip or hesitate during uphill climbs or heavy towing, often misdiagnosed as clutch failure.
• Metal debris in transmission fluid: Flakes or fine metallic particles found during oil changes signal that the spur gear’s hardened surface is spalling. This debris can quickly damage the 0750117075 TAPER ROLLER BEARING and the 2095309059 DIFF.HOUSING.
• Increased backlash or driveline clunk: Excessive play between the spur gear and its mating differential gear creates a noticeable clunk when shifting between drive and reverse, indicating advanced wear.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 series transmissions. It is also compatible with select variants of the WG180 and WG200 series when used in conjunction with the correct differential housing. Always verify your transmission model suffix before installation. The gear interfaces directly with the 2095309081 DIFFERENTIAL AXLE and requires precise alignment with the 4482360002 AXLE BEVEL GEAR for optimal performance.
