Overview
The ZF 2094.304.074 GEAR is a precision-machined helical gear designed for the auxiliary drive train within ZF’s WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 2094.304.074, sits on the intermediate shaft and transfers torque from the input shaft to the output planetary set. It is housed within the main casing, which is sealed by the 2094101012: TRANSMISSION HOUSING and supported by the 2094301036: HOUSING assembly. Without this gear, the transmission cannot achieve its rated power flow, making it a critical component for driveline integrity.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create uneven contact patterns, producing a distinct high-pitched whine that intensifies under load.
- Intermittent gear slipping under heavy torque: As the gear surface degrades, the meshing engagement becomes irregular, causing momentary loss of drive in forward gears.
- Metal particles in transmission fluid: Flaking or pitting of the gear teeth releases ferrous debris into the oil, often visible during routine drain intervals.
- Vibration in the driveline at specific RPM ranges: A damaged gear profile induces harmonic vibrations that can be felt through the chassis, particularly between 1500–2500 RPM.
