ZF 2095.345.003 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.345.003 GEAR is a precision-machined helical gear designed for the auxiliary drive and power take-off (PTO) train within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers torque from the input shaft to the differential assembly, ensuring smooth power distribution under heavy load. The SKU 2095.345.003 sits directly on the countershaft cluster, meshing with the output gear set to maintain synchronized rotation. When paired with a properly functioning 5838109007: DIFFERENTIAL, this gear maintains consistent backlash and load capacity across all forward and reverse ranges.

Symptoms of Failure

• Whining or howling noise during deceleration: Worn gear teeth create irregular contact patterns, producing a distinct metallic whine that intensifies as vehicle speed drops below 30 mph.
• Intermittent gear slipping under load: Excessive wear on the gear face reduces tooth engagement, causing momentary power loss when climbing grades or towing heavy trailers.
• Metal particles in transmission fluid: Flaking or pitting on the gear surface sheds ferrous debris into the oil, often visible during routine drain intervals or on the magnetic drain plug.
• Hard shifting or delayed engagement: Damaged gear teeth disrupt the synchronization between the input shaft and the 2095209019: DIFFERENTIAL, leading to clunky shifts and hesitation when moving from neutral to drive.

Technical Specifications

Compatibility

This gear is engineered for ZF WG-series transmissions with a modular auxiliary drive configuration. It is a direct replacement for the following models:

• ZF WG100 (all sub-variants, 1998–2012)
• ZF WG130 (including WG130-1 and WG130-2)
• ZF WG131 (early and late production)
• ZF WG180 (limited to units with 37-tooth countershaft gear)
• ZF WG200 (only when used with 0750117075: TAPER ROLLER BEARING for shaft support)

Installation requires a 0631329086: SPRING PIN to secure the gear to the shaft. Always inspect the mating differential and thrust washers during replacement to prevent premature wear.
