ZF 2094.311.023 SIDE SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.311.023 SIDE SHAFT is a critical power-transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part transmits rotational force from the differential gear set to the wheel hub, ensuring smooth torque delivery under heavy industrial loads. As a precision-machined shaft, it interfaces directly with the 2094101012 TRANSMISSION HOUSING and the 2094301036 HOUSING to maintain proper gear alignment. The SKU 2094.311.023 is manufactured to ZF’s original tolerances, guaranteeing exact fitment and long service life in demanding applications such as construction equipment, agricultural machinery, and material handling vehicles.

Symptoms of Failure

• Side shaft oil leaks at the housing seal – Worn splines or bearing surfaces cause the shaft to wobble, breaking the 0750111371 SHAFT SEAL and allowing transmission fluid to escape.
• Intermittent gear slipping under load – A fatigued side shaft can lose engagement with the differential side gears, producing a clunking sensation during acceleration or turning.
• Vibration or driveline shudder – Bent or cracked shafts create harmonic imbalance, felt as low-frequency vibration through the chassis at speeds above 15 mph.
• Metal debris in transmission fluid – Fretting wear on the shaft’s spline ends generates fine metallic particles that contaminate the oil, often found during routine fluid changes.

Technical Specifications

Compatibility

This side shaft is specifically designed for ZF’s WG-series powershift transmissions. Based on its spline geometry and length, the 2094.311.023 is compatible with the following models: WG100, WG130, WG131, WG180, and WG200. It also fits select variants of the WG150 and WG250 series when used with the correct 2094298057 HOUSING and 2094301071 COVER. Always verify the shaft’s spline count (typically 28 teeth) against your transmission’s differential carrier before installation.
