ZF 2094.311.049 SIDE SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.311.049 SIDE SHAFT is a critical power transfer component within the WG100, WG130, and WG131 transmission assemblies. This OEM genuine part transmits rotational force from the differential gear set to the wheel hub, ensuring smooth torque delivery under heavy industrial loads. The SKU 2094.311.049 is precision-machined to ZF’s exacting tolerances, designed to withstand high axial and radial stresses encountered in construction and agricultural machinery. It interfaces directly with the 2094101012: TRANSMISSION HOUSING and the 2094301036: HOUSING, forming a sealed, lubricated assembly that prevents contamination ingress.

Symptoms of Failure

• Oil leaks at wheel end: Worn side shaft seals or bearing surfaces allow transmission fluid to escape, leaving visible drips near the hub. This often accompanies degraded 0750111371: SHAFT SEAL components.
• Gear slipping under load: When the side shaft splines wear, torque transfer becomes intermittent, causing the vehicle to lurch or lose power during acceleration. This symptom worsens when paired with a failing 2094298057: HOUSING.
• Abnormal vibration from driveline: A worn side shaft creates rhythmic thumping or shuddering, particularly at low speeds, indicating bearing surface degradation or shaft imbalance.
• Metallic grinding noise during turns: Damaged side shaft bearings produce a distinct grinding sound when the transmission is under side load, often requiring replacement of the 2094301071: COVER assembly.

Technical Specifications

Compatibility

This side shaft is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used with the correct 0634303085: O-RING and 2094301030: GASKET kits. The part fits both left and right side positions in the differential housing. Always verify spline engagement with the 0631306670: CYLINDRICAL PIN alignment before installation.
