Overview
The ZF 2094.346.056 SPUR GEAR is a precision-engineered component designed for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transmits rotational force from the input shaft to the hydraulic pump drive, ensuring consistent oil flow for clutch actuation and lubrication. As a hardened steel spur gear, it directly meshes with the idler gear cluster inside the transmission housing. The SKU 2094.346.056 is factory-matched to ZF’s original tolerances, eliminating the risk of backlash or premature wear found in aftermarket substitutes.
Symptoms of Failure
- Whining or grinding noise from the transmission bell housing – A worn 2094.346.056 spur gear produces a high-pitched metallic whine during acceleration or deceleration, often mistaken for bearing failure. This noise intensifies when the PTO is engaged under load.
- Intermittent PTO engagement or slipping – If the gear teeth are chipped or worn unevenly, the hydraulic pump loses synchronization, causing the PTO to disengage unexpectedly or fail to hold torque during heavy lifting operations.
- Metal particles in transmission oil filter – Flaking or spalling of the gear’s case-hardened surface releases ferrous debris into the oil circuit. This contaminates the valve body and accelerates wear on the 2094009020: T 7336 L thrust washer assembly.
- Oil seepage around the PTO housing gasket – Excessive gear vibration from a damaged spur gear can loosen the 2094301030: GASKET seal, leading to visible oil drips near the transmission side cover.

Compatibility
This spur gear is engineered exclusively for ZF’s WG-series powershift transmissions. It is a direct fit for the WG100, WG130, and WG131 models, where it mounts on the countershaft inside the 2094101017: TRANSMISSION HOUSING. The gear also interfaces with the 2094298054: HOUSING and 2094301069: HOUSING sub-assemblies that support the PTO drive train. It is not compatible with WG180 or WG200 series units without additional adapter modifications.
