ZF 2094.310.065 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.310.065 GEAR is a precision-engineered helical gear designed for the intermediate shaft cluster within the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 2094.310.065, is responsible for transferring torque from the input shaft to the output shaft via the countershaft, directly influencing gear ratio stability and overall drivetrain efficiency. It sits in the lower gear train assembly, meshing with companion gears to ensure smooth power delivery under heavy load conditions. When replacing this gear, it is critical to inspect the adjacent 2094101012: TRANSMISSION HOUSING for wear, as housing deformation can accelerate gear tooth fatigue.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth on the 2094.310.065 produce a distinct high-pitched whine that increases with road speed, often misdiagnosed as bearing noise.
• Intermittent gear slippage under load: As the gear profile wears, the transmission may momentarily lose torque transfer when climbing grades or hauling heavy loads, causing a brief RPM flare.
• Metallic debris in transmission fluid: Flaking or pitting of the gear surface introduces fine steel particles into the oil, which can be observed during routine fluid changes or when inspecting the magnetic drain plug.
• Hard shifting or gear clash: Excessive backlash from a worn 2094.310.065 gear disrupts synchronizer timing, leading to grinding when engaging forward gears.

Technical Specifications

Compatibility

This genuine ZF gear is engineered for the WG100, WG130, and WG131 series transmissions, which are commonly found in medium-duty commercial vehicles and industrial machinery. It is also compatible with the WG180 and WG200 series when used in the intermediate shaft position, though cross-referencing the transmission serial number is recommended. During installation, always replace the 2094301036: HOUSING gasket surface and inspect the 2094298057: HOUSING for cracks. The 2094301071: COVER must be torqued to specification to maintain proper gear end-play.
