ZF 2094.304.050 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.304.050 GEAR is a precision-machined helical gear designed for the auxiliary drive train within the WG100, WG130, and WG131 transmission series. This OEM genuine component transfers torque from the input shaft to the countershaft assembly, directly influencing gear ratio stability and load distribution. As a critical element in the power flow path, the 2094.304.050 gear ensures smooth engagement under high-torque conditions. It is frequently replaced alongside the 2094101017: TRANSMISSION HOUSING and the 2094301069: HOUSING, as these components share the same lubrication and alignment tolerances.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth produce a distinct high-pitched sound, especially under load, indicating surface fatigue or pitting on the 2094.304.050 gear.
• Intermittent gear slippage in lower ranges: A failing gear can cause momentary loss of torque transfer, leading to hesitation or “jumping” out of engagement in WG100/WG130 units.
• Metallic debris in transmission fluid: Flaking or chipped teeth shed ferrous particles into the oil, often visible during drain intervals. This symptom frequently requires simultaneous inspection of the 2094298054: HOUSING for contamination.
• Hard shifting or gear clash: Excessive backlash from a worn gear disrupts synchronizer timing, causing grinding when moving between ratios.

Technical Specifications

Compatibility

This gear is engineered for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in the auxiliary drive position, provided the housing assembly matches. The 2094.304.050 gear interfaces directly with the 0636302008: SCREW PLUG for oil retention and requires proper sealing via the 0634801165: SEALING RING to prevent contamination. Always verify shaft alignment with the 0750111371: SHAFT SEAL during installation.
