ZF 2095.346.040 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.346.040 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) systems within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force from the main shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. The SKU 2095.346.040 is manufactured to exact ZF tolerances, guaranteeing a direct fit and long service life. When paired with a 5838109006: DIFFERENTIAL, this spur gear forms the critical link between the gearbox output and final drive reduction.

Symptoms of Failure

• Whining or howling noise during deceleration: Worn gear teeth create a distinct high-pitched sound, often misdiagnosed as bearing failure. This indicates uneven tooth contact or pitting on the spur gear.
• Intermittent power loss to PTO: If the spur gear skips or slips, auxiliary equipment (e.g., hydraulic pumps) will lose RPM, causing erratic operation. This is a classic sign of stripped or chipped teeth.
• Metallic debris in transmission fluid: Flakes or fine silver particles in the oil filter or drain plug signal advanced wear on the 2095.346.040 gear face. This often accompanies a failing 0750117075: TAPER ROLLER BEARING.
• Vibration at specific road speeds: A worn spur gear creates cyclic vibration that intensifies under load, particularly in the 30-45 mph range, indicating uneven tooth wear.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in the auxiliary drive position. The gear interfaces directly with the 2095209037: DIFFERENTIAL and is housed within the 2095309059: DIFF.HOUSING. Always verify the tooth count and bore size against your existing part before installation.
