ZF 4108.322.043 SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4108.322.043 SHAFT is a precision-machined component designed for the internal power transfer assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part serves as the primary rotational axis for gear clusters, ensuring smooth torque delivery from the input to the output shaft. The SKU 4108.322.043 is engineered to maintain exacting tolerances, reducing vibration and wear in high-cycle industrial applications. It sits directly within the main gear housing, interfacing with the 4108101057: HOUSING and the 4108201177: HOUSING to form the core drivetrain assembly.

Symptoms of Failure

• Gear Slipping Under Load: A worn shaft can cause misalignment, leading to intermittent gear disengagement during heavy operation.
• Excessive Vibration or Noise: Bearing surface wear on the shaft produces a distinct whining or grinding sound, especially at higher RPMs.
• Oil Leaks Around the Output Flange: Shaft wear can compromise the seal surface, causing transmission fluid to escape past the 0636302056: SCREW PLUG and adjacent gaskets.
• Hard Shifting or Delayed Engagement: A bent or fatigued shaft disrupts the synchromesh timing, resulting in sluggish gear changes.

Technical Specifications

Compatibility

This shaft is specifically engineered for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with select variants of the WG180 and WG200 models where the internal gear train uses the same spline pitch and bearing spacing. Always verify the shaft length against your existing assembly. For complete rebuilds, pair this shaft with the 4108301304: BEARING COVER to secure the output bearing and prevent axial play.
