ZF 2095.310.005 SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.310.005 SHAFT (SKU: 2095.310.005) is a precision-machined OEM genuine component designed for the internal gear train of ZF WG100, WG130, and WG131 transmissions. This shaft serves as the primary rotational axis for the planetary gear sets, transferring torque from the input shaft to the differential assembly. It sits directly within the transmission housing, interfacing with the 5838109007: DIFFERENTIAL to ensure smooth power distribution. As a hardened steel component, it maintains critical alignment under heavy loads, preventing gear misalignment and excessive wear in commercial vehicle drivetrains.

Symptoms of Failure

• Transmission whining or grinding noise during acceleration: A worn 2095.310.005 shaft often produces a distinct metallic whine that increases with engine RPM, indicating bearing surface degradation or shaft scoring.
• Intermittent gear slipping under load: When the shaft loses its surface hardness or develops torsional fatigue, the connected gears may momentarily lose engagement, causing a slipping sensation during uphill climbs or heavy hauling.
• Oil leaks near the transmission output housing: A bent or cracked shaft can compromise the seal interface, leading to gradual ATF seepage around the output flange area.
• Vibration in neutral or drive: Excessive radial play from a worn shaft causes harmonic vibrations that are felt through the chassis, particularly at highway speeds.

Technical Specifications

Compatibility

This shaft is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 variants when used in conjunction with the 0750117075: TAPER ROLLER BEARING for proper axial support. For differential-side applications, the 2095209019: DIFFERENTIAL is a direct mating component. The shaft is secured in place using the 0631329086: SPRING PIN, which prevents rotational slippage during high-torque events.
