ZF 2094.104.006 MAIN SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.104.006 MAIN SHAFT is a critical rotating component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part serves as the primary torque-transfer member within the gear train, connecting the input drive to the output flange through the planetary sets. The SKU 2094.104.006 is precision-machined to maintain exact axial alignment and spline engagement, ensuring smooth power delivery under heavy-duty industrial loads. When installed alongside the 2094104412 MAIN SHAFT or the 2094106010 SHIFT SYSTEM, this shaft forms the backbone of the transmission’s rotating assembly.

Symptoms of Failure

• Gear slipping under load: Worn splines on the 2094.104.006 cause intermittent disengagement, leading to power loss during acceleration or climbing.
• Vibration and driveline shudder: A bent or fatigued main shaft produces rhythmic shaking that intensifies at specific RPM ranges, often misdiagnosed as a clutch issue.
• Metallic debris in transmission fluid: Flaking or spalling on the shaft surface contaminates the oil, visible as silver particles on the dipstick or filter.
• Hard shifting or gear clash: Axial play from a worn shaft interferes with the 2094206001 GEARSHIFT SHAFT, causing delayed or grinding engagement.

Technical Specifications

Compatibility

This main shaft is specifically designed for the ZF WG100, WG130, and WG131 series transmissions. It also fits select variants of the WG180 and WG200 models when used with the correct 2094304054 MAIN SHAFT as a companion part. Always verify the spline count and shaft length against your transmission’s service manual. The 2094.104.006 is not compatible with WG150 or WG250 series without additional adapter components.
