ZF 2094.303.067 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.303.067 GEAR is a precision-machined helical gear designed for the intermediate shaft assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers torque from the input shaft to the countershaft, directly influencing gear ratio stability and load distribution across the drivetrain. The SKU 2094.303.067 is manufactured to ZF’s original tolerances, ensuring backlash consistency and reduced noise, vibration, and harshness (NVH) during operation. When installed alongside the 2094104412: MAIN SHAFT and the 2094106010: SHIFT SYSTEM, this gear forms the core of the transmission’s power delivery path.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth on the 2094.303.067 produce a distinct high-pitched whine that intensifies under load, often misdiagnosed as bearing failure.
• Hard shifting or gear clash: Excessive tooth wear or pitting disrupts synchronizer timing, causing grinding when engaging forward gears, particularly in WG130 units.
• Metallic debris in transmission fluid: Flaking or spalling from the gear’s case-hardened surface contaminates the oil, accelerating wear on the 2094304054: MAIN SHAFT and adjacent bearings.
• Intermittent power loss under torque: Stripped or chipped teeth cause momentary slippage, especially during hill climbs or heavy hauling, triggering fault codes in electronic shift systems.

Technical Specifications

Compatibility

This gear is engineered specifically for ZF WG-series mechanical transmissions. Verified compatible models include WG100, WG130, and WG131 variants used in medium-duty trucks, agricultural tractors, and industrial material handlers. It also fits select WG180 and WG200 configurations when paired with the correct 2094206001: GEARSHIFT SHAFT. Always confirm the tooth count and spline interface against your transmission’s parts manual before installation.
