ZF 2095.318.010 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.318.010 SPUR GEAR is a precision-machined component engineered for the power-dividing section of ZF WG-series transmissions. Positioned within the differential carrier assembly, this gear transfers torque from the input shaft to the planetary gear set, enabling smooth load distribution under heavy-duty conditions. As an OEM genuine part (SKU: 2095.318.010), it ensures exact tooth geometry and metallurgical integrity, critical for maintaining gear mesh alignment and preventing premature wear in WG100, WG130, and WG131 models.

Symptoms of Failure

• Whining or howling noise during acceleration — Worn spur gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
• Intermittent gear slipping or loss of drive — Chipped or pitted teeth fail to engage properly, causing momentary power loss, especially when climbing grades or towing.
• Metallic debris in transmission fluid — Flaking or spalling from the gear surface contaminates the oil, often visible during routine drain intervals.
• Vibration through the driveline — Uneven wear on the spur gear induces cyclical imbalance, felt as a shudder in the chassis at specific RPM ranges.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 transmission series. It also fits select variants of the WG180 and WG200 models when used in conjunction with the correct differential housing. Always verify your transmission’s serial number against the OEM parts catalog before ordering. For complete assembly, pair this gear with the 2095109019 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING to ensure proper axial support. The 2095209037 DIFFERENTIAL and 2095309059 DIFF.HOUSING are also commonly replaced during the same service interval.
