Overview
The ZF 2094.346.052 GEAR is a precision-engineered component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part functions as a critical power transfer element within the gear train, meshing directly with adjacent shafts to modulate torque and rotational speed. Positioned in the intermediate shaft assembly, the 2094.346.052 gear ensures synchronized engagement between the 2094101012: TRANSMISSION HOUSING and the output drive. Its hardened tooth profile minimizes backlash, maintaining driveline stability under heavy industrial loads. The SKU 2094.346.052 is manufactured to ZF’s original tolerances, guaranteeing direct interchangeability without modification.
Symptoms of Failure
- Audible whining or grinding noise during gear engagement: Worn teeth on the 2094.346.052 gear create irregular contact patterns, producing a high-pitched sound that intensifies under load. This often indicates pitting or spalling on the tooth flanks.
- Intermittent gear slipping under torque: As the gear’s involute profile degrades, it fails to maintain positive engagement with mating shafts, causing momentary power loss during acceleration or hill climbs.
- Metallic debris in transmission fluid: Fractured gear teeth shed microscopic particles into the oil, visible during drain intervals. This accelerates wear on adjacent components like the 2094301036: HOUSING and bearings.
- Vibration at specific RPM ranges: Uneven tooth wear creates harmonic imbalances, transmitting through the 2094298057: HOUSING and felt as chassis shudder between 1500-2000 RPM.

Compatibility
This gear is engineered for ZF’s WG-series industrial transmissions, specifically the WG100, WG130, and WG131 models. It also retrofits into the WG180 and WG200 variants when paired with the correct 2094301071: COVER and shaft seal kit. Always verify tooth count and spline interface before installation. The 2094.346.052 gear is not compatible with WG80 or WG250 series without adapter modifications.
