ZF 2095.303.049 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.049 GEAR is a precision-machined helical gear designed for the internal power flow path within ZF WG100, WG130, and WG131 transmissions. This genuine OEM part transfers torque from the input shaft to the countershaft assembly, directly influencing gear ratio stability and load distribution. Located in the upper gear train cluster, the SKU 2095.303.049 ensures synchronized engagement under heavy-duty industrial conditions. When paired with a properly maintained 2095109020: DIFFERENTIAL, this gear maintains consistent rotational alignment, reducing parasitic drag across the driveline.

Symptoms of Failure

• Audible whining or grinding noise during acceleration: Worn gear teeth create irregular contact patterns, producing a high-pitched whine that intensifies under load. This is a common long-tail search query for “ZF transmission whining noise when accelerating.”
• Intermittent gear slippage under heavy torque: As the gear surface degrades, it loses positive engagement with mating components, causing momentary power loss during uphill or loaded operation.
• Metallic debris in transmission oil: Flaking or pitting on the gear flanks releases ferrous particles into the lubricant, often detected during routine oil changes or magnetic drain plug inspections.
• Vibration at specific RPM ranges: Unbalanced wear on the 2095.303.049 gear induces harmonic vibrations that resonate through the transmission housing, particularly between 1800-2200 RPM.

Technical Specifications

Compatibility

This gear is engineered for the WG-series modular transmission family. Primary fitment includes ZF WG100, WG130, and WG131 models used in agricultural tractors, construction loaders, and industrial material handlers. The 2095.303.049 also integrates with select WG180 and WG200 variants where the input gear cluster shares identical tooth geometry and shaft spline dimensions. For differential-side compatibility, verify the 2095209037: DIFFERENTIAL and 2095309059: DIFF.HOUSING are free from scoring marks before installation. The 0750117075: TAPER ROLLER BEARING supports the gear’s axial load and must be replaced concurrently to prevent premature wear.
