ZF 2095.310.044 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.310.044 SPUR GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part sits within the gear train assembly, directly meshing with the differential to convert rotational speed into torque for the drive axles. The SKU 2095.310.044 is precision-machined to ZF’s factory tolerances, ensuring minimal backlash and optimal load distribution under heavy-duty industrial conditions. When installed alongside a 5838109021 DIFFERENTIAL, this spur gear maintains synchronized rotation across the output shafts, reducing vibration and extending service intervals.

Symptoms of Failure

• Whining or howling noise during acceleration – Worn gear teeth create uneven contact patterns, producing a distinct high-pitched sound that intensifies under load.
• Metal debris in transmission fluid – Flaking or pitting on the spur gear’s tooth flanks releases ferrous particles into the oil, often visible during drain intervals.
• Intermittent gear slipping under torque – As the gear profile degrades, the transmission may momentarily lose engagement, causing sudden RPM surges without corresponding speed increases.
• Vibration through the chassis at specific speeds – A worn 2095.310.044 spur gear induces cyclical imbalances that resonate through the driveline, particularly during deceleration.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF’s WG-series powershift transmissions. It is a direct fit for the WG100, WG130, and WG131 models, which are commonly used in wheel loaders, forklifts, and industrial tractors. The gear interfaces with the 2095209019 DIFFERENTIAL assembly and requires a 0750117075 TAPER ROLLER BEARING for proper axial support. During installation, a 0631329086 SPRING PIN is used to secure the gear to its shaft. While primarily for WG100/WG130/WG131, it may also suit select WG180 and WG200 variants with identical gear ratios—always verify tooth count and bore dimensions before ordering.
