ZF 2095.204.007 MAIN SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.204.007 MAIN SHAFT is a critical rotating component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits torque from the input shaft to the output assembly, directly influencing gear engagement and driveline stability. The SKU 2095.204.007 is precision-machined to factory tolerances, ensuring concentric rotation within the planetary gear sets. When installed alongside a 5838109007: DIFFERENTIAL, this main shaft supports load distribution across the axle system. It also interfaces with the 0750117075: TAPER ROLLER BEARING to manage axial and radial forces during high-torque operations.

Symptoms of Failure

• Transmission gear slipping under load – A worn main shaft can cause intermittent power loss, especially when climbing or hauling heavy loads.
• Vibration or whining noise from the gearbox – Surface wear or scoring on the shaft creates harmonic vibrations that amplify with speed.
• Oil contamination with metallic debris – Flaking or spalling of the shaft material introduces ferrous particles into the transmission fluid.
• Difficulty engaging or disengaging gears – Misalignment due to shaft wear prevents smooth synchronizer operation.

Technical Specifications

Compatibility

This main shaft is specifically designed for the ZF WG100, WG130, and WG131 transmission models. It is also compatible with certain variants of the WG180 and WG200 series when used with the correct bearing stack. For differential-side integration, pair this shaft with the 2095209019: DIFFERENTIAL to ensure proper gear mesh. Secure the assembly using the 0631329086: SPRING PIN to prevent axial movement during operation.
