Overview
The ZF 2094.304.070 GEAR is a precision-engineered helical gear designed for the auxiliary drive train within the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational torque from the input shaft to the intermediate shaft assembly, ensuring smooth power distribution under heavy load conditions. The SKU 2094.304.070 is manufactured to ZF’s original metallurgical specifications, featuring case-hardened alloy steel for extended service life in off-highway and industrial applications. It sits directly behind the 2094101012: TRANSMISSION HOUSING and interfaces with the 2094301036: HOUSING to maintain precise gear mesh alignment.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load. This is a common indicator of pitting or spalling on the gear flank.
- Intermittent gear slipping under torque: When the 2094.304.070 gear loses its hardened surface layer, it can no longer maintain positive engagement, causing momentary power loss during shifting or uphill operation.
- Metallic debris in transmission fluid: Fractured gear teeth or advanced wear will shed ferrous particles into the oil, often visible during routine drain intervals or when inspecting the magnetic drain plug.
- Vibration through the shift lever or chassis: Uneven tooth wear or a bent gear shaft creates cyclic vibration that transmits through the 2094298057: HOUSING and 2094301071: COVER assemblies.

Compatibility
This gear is a direct replacement for the following ZF transmission models: WG100, WG130, WG131, WG180, and WG200 series. It is also used in select WG120 and WG150 variants produced after 2005. Always verify the tooth count and spline interface against your existing part before installation. The 2094.304.070 gear works in conjunction with the 2094101012: TRANSMISSION HOUSING and 2094301036: HOUSING to maintain proper bearing preload and gear backlash.
