ZF 2095.345.019 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.345.019 GEAR is a critical helical-cut component engineered for the auxiliary drive and power take-off (PTO) assemblies within the WG100, WG130, and WG131 transmission series. This OEM genuine part ensures precise torque transfer from the input shaft to the differential housing, directly influencing driveline smoothness and load distribution. The SKU 2095.345.019 identifies a hardened steel gear designed to mesh with mating shafts under high cyclic loads. When installed, it sits adjacent to the 5838109007: DIFFERENTIAL, converting rotational speed into usable power for auxiliary systems. Its tooth profile and surface finish are critical for maintaining backlash tolerances and reducing noise, vibration, and harshness (NVH) in heavy-duty industrial applications.

Symptoms of Failure

• Whining or howling noise during PTO engagement — Worn teeth on the 2095.345.019 gear produce a distinct high-pitched sound under load, often misdiagnosed as bearing failure. This noise typically escalates when the 0750117075: TAPER ROLLER BEARING supporting the gear begins to degrade.
• Intermittent gear slipping under heavy torque — As the gear’s tooth flank wears, it loses engagement with the mating shaft, causing momentary power loss during acceleration or hill climbs. This symptom is often accompanied by metal particles in the transmission fluid.
• Oil leaks from the PTO housing seal — Excessive gear play from a worn 2095.345.019 can stress the housing bore, leading to seal distortion and fluid seepage around the output flange.
• Vibration in the driveline at specific RPM ranges — Uneven tooth wear creates harmonic imbalances, felt as a shudder through the chassis when the transmission is under load between 1,200 and 1,800 RPM.

Technical Specifications

Compatibility

This gear is specifically designed for the ZF WG100, WG130, and WG131 powershift transmission families. It is also compatible with select WG180 and WG200 variants that share the same auxiliary drive geometry. The 2095.345.019 gear interfaces directly with the 2095209019: DIFFERENTIAL assembly and is secured using the 0631329086: SPRING PIN to prevent axial migration. Always verify the transmission serial number against ZF’s parts catalog before installation, as minor spline variations exist between early and late production runs of the WG130 series.
