ZF 2095.346.085 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.346.085 SPUR GEAR is a precision-machined OEM component engineered for the planetary gear sets within ZF WG100, WG130, and WG131 transmissions. This gear transfers torque from the input shaft to the differential assembly, directly influencing power delivery and drivetrain efficiency. As a genuine ZF part, SKU 2095.346.085 ensures exact tooth geometry and metallurgical integrity, preventing premature wear in high-load applications. It sits adjacent to the 2095109015 DIFFERENTIAL and works in concert with the 2095209037 DIFFERENTIAL to maintain synchronized rotation under heavy torque.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn spur gear teeth create irregular meshing, producing a distinct high-pitched sound that intensifies under load.
• Intermittent gear slipping or delayed engagement: Damaged tooth flanks cause the gear to lose positive contact with mating components, leading to erratic power transfer.
• Metallic debris in transmission fluid: Flaking or pitting on the gear surface sheds particles into the oil, often visible during routine drain intervals.
• Vibration through the driveline at steady speeds: Uneven wear patterns induce rotational imbalance, felt as a persistent shudder in the chassis.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 transmission models. It is also compatible with select variants of the WG180 and WG200 series when used in conjunction with the 0750117075 TAPER ROLLER BEARING and the 2095309059 DIFF.HOUSING. Always verify your transmission serial number before installation to ensure correct fitment.
