Overview
The ZF 2095.346.087 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force from the input shaft to the differential assembly, ensuring synchronized gear engagement under load. The SKU 2095.346.087 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification. It sits adjacent to the 2095109020 DIFFERENTIAL and the 2095209037 DIFFERENTIAL, forming the core of the gear train that distributes torque to the axles.
Symptoms of Failure
- Whining or howling noise during deceleration: Worn spur gear teeth create a distinct high-pitched sound, especially when the transmission is under light load or coasting. This often indicates pitting or chipping on the gear face.
- Intermittent gear slipping in auxiliary drive: If the spur gear loses tooth contact due to wear, the PTO may disengage unexpectedly, causing a momentary loss of hydraulic pressure or drive power.
- Metallic debris in transmission fluid: Flakes or fine silver particles found during oil changes point to spur gear degradation. This symptom accelerates damage to the 0750117075 TAPER ROLLER BEARING and the 2095309059 DIFF.HOUSING.
- Vibration at specific RPM ranges: Uneven wear on the spur gear causes harmonic vibrations that resonate through the transmission case, often misdiagnosed as a bearing issue.

Compatibility
This spur gear is designed exclusively for ZF’s WG-series mechanical transmissions. Verified compatible models include WG100, WG130, and WG131. It is also used in select variants of the WG180 and WG200 series where the auxiliary drive configuration matches the 23-tooth gear set. Always cross-reference your transmission’s serial number with the SKU 2095.346.087 before installation. The gear interfaces directly with the 2095309081 DIFFERENTIAL AXLE and the 4482360002 AXLE BEVEL GEAR.
