Overview
The ZF 2094.311.061 SHAFT (SKU: 2094.311.061) is a precision-machined component engineered for the internal power flow of ZF WG100, WG130, and WG131 transmissions. This genuine OEM shaft serves as the primary torque transfer element within the gear train, connecting the input drive to the planetary gear sets. It sits centrally within the main transmission housing, rotating on bearings to deliver consistent power under heavy industrial loads. As a critical rotating assembly part, its integrity directly impacts shift quality and overall driveline efficiency. When replacing this shaft, it is essential to inspect the surrounding 2094101018: TRANSMISSION HOUSING for wear, as misalignment can accelerate shaft fatigue.
Symptoms of Failure
- Gear slipping under load: A worn 2094.311.061 shaft can cause the transmission to unexpectedly drop out of gear or hesitate during acceleration, particularly in WG100 models operating at high torque.
- Metallic grinding noise from the bell housing: When the shaft splines or bearing journals degrade, operators often report a distinct grinding or whining sound that intensifies with vehicle speed.
- Oil contamination with metal debris: Flaking or pitting on the shaft surface introduces ferrous particles into the hydraulic circuit, often visible during oil changes as a metallic sludge.
- Vibration through the drivetrain: An unbalanced or bent shaft produces low-frequency vibration that can be felt through the chassis, especially during deceleration.

Compatibility
This genuine ZF shaft is specifically designed for the following transmission models: WG100, WG130, and WG131. It is also compatible with select variants of the WG180 and WG200 series where the shaft length and spline configuration match. Always verify the transmission serial number before installation. During rebuilds, the 2094301069: HOUSING and 2094298054: HOUSING must be checked for concentricity, as housing distortion can cause premature shaft failure. Additionally, the 2094301071: COVER should be replaced if its pilot bore shows scoring.
