ZF 2095.318.008 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.318.008 SPUR GEAR is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This gear sits within the countershaft assembly, directly transferring rotational force from the input shaft to the differential system. As a critical power-transmission element, it ensures smooth torque delivery under heavy loads. The SKU 2095.318.008 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in commercial vehicle drivelines.

Symptoms of Failure

• Whining or grinding noise during acceleration – Worn spur gear teeth create a high-pitched metallic sound, especially under load, indicating surface fatigue or pitting.
• Intermittent gear slipping or loss of drive – When the spur gear’s tooth profile degrades, it fails to maintain positive engagement, causing momentary power loss or hesitation.
• Metal particles in transmission oil – Flaking or chipped gear teeth shed debris into the lubricant, visible during oil changes as glitter or fine metallic sludge.
• Vibration through the gearshift lever – Uneven wear on the spur gear induces driveline vibration that transmits into the cab, worsening at specific RPM ranges.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 transmissions. It also fits select variants of the WG180 and WG200 series when used with the correct countershaft assembly. Always verify your transmission model and serial number before ordering. The gear interfaces directly with the 2095109020 DIFFERENTIAL and the 2095209037 DIFFERENTIAL unit, while the 0750117075 TAPER ROLLER BEARING supports its axial load. The 2095309059 DIFF.HOUSING encloses the entire gearset for protection.
