ZF 4108.322.059 SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4108.322.059 SHAFT is a precision-machined internal component engineered for the WG100, WG130, and WG131 transmission series. This genuine OEM part functions as the primary torque-transfer element within the gear train, connecting the planetary carrier to the output assembly. Designed to withstand high cyclic loads, the shaft ensures synchronized rotation between the 4108101127: HOUSING and the 4108201277: HOUSING during power shifts. The SKU 4108.322.059 is a direct replacement for worn shafts in heavy-duty industrial transmissions, maintaining factory-specified clearances and spline engagement.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: A worn 4108.322.059 shaft can cause hesitation when the transmission attempts to engage forward or reverse gears, often accompanied by a grinding noise.
• Vibration under load: Excessive play in the shaft leads to driveline shudder, particularly during acceleration or when hauling heavy loads.
• Oil contamination with metallic debris: Flaking or pitting on the shaft surface sheds fine metal particles into the transmission fluid, visible during routine oil changes.
• Intermittent loss of power to wheels: Spline wear on the shaft can cause momentary torque slip, resulting in a sensation of the transmission “falling out of gear” under strain.

Technical Specifications

Compatibility

This shaft is specifically validated for ZF WG100, WG130, and WG131 transmissions. It also fits select variants of the WG180 and WG200 series when used in conjunction with the 4108301304: BEARING COVER and a fresh 4108306173: GASKET. Always verify the spline count and overall length against your existing shaft before installation. The 4108.322.059 is not backward-compatible with pre-1990 WG series units without adapter modifications.
