ZF 2095.303.042 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.042 GEAR is a precision-machined helical gear engineered for the internal power transfer assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part sits on the intermediate shaft, meshing directly with the main drive gear to transmit torque from the engine to the output shaft. As a critical component in the gear train, the SKU 2095.303.042 ensures smooth, quiet operation under heavy loads. When replacing this gear, it is common to also inspect the 2095109016: DIFFERENTIAL and the 2095209037: DIFFERENTIAL for wear, as they share the same lubrication circuit and load path.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth create excessive backlash, producing a distinct high-pitched sound that intensifies under load.
• Metal shavings in transmission fluid: Flaking or pitting on the gear surface contaminates the oil, often visible during routine drain intervals.
• Intermittent gear slipping or hesitation: Damaged tooth profiles fail to maintain positive engagement, causing momentary loss of power transfer.
• Vibration through the shift lever or chassis: Uneven wear on the gear’s helical cut induces harmonic vibrations that resonate through the driveline.

Technical Specifications

Compatibility

This gear is designed exclusively for ZF’s WG-series industrial transmissions. Verified fitment includes the WG100, WG130, and WG131 models. It may also be compatible with the WG180 and WG200 series when used in specific gear ratio configurations, though cross-referencing with the transmission’s serial number is recommended. During installation, always replace the 0750117075: TAPER ROLLER BEARING and inspect the 2095309059: DIFF.HOUSING for cracks or scoring.
