ZF 2095.309.065 PLANETARY GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.309.065 PLANETARY GEAR is a critical rotating assembly within the WG100, WG130, and WG131 transmission families. This OEM genuine component functions as the primary torque-splitting element in the planetary gearset, transferring engine power from the sun gear to the carrier while reducing rotational speed. Positioned directly in the main drive path, the 2095.309.065 gear set works in concert with the 2095109020: DIFFERENTIAL to manage load distribution across the axle. Precision-ground teeth and case-hardened metallurgy ensure this SKU withstands continuous high-torque cycles in heavy-duty industrial applications.

Symptoms of Failure

• Whining or growling noise during acceleration – Worn planetary gears produce a distinct metallic whine that intensifies under load, often mistaken for wheel bearing noise.
• Intermittent gear slipping under heavy load – When the planetary carrier loses tooth engagement, the transmission may momentarily lose drive power, especially during uphill climbs or when towing.
• Metallic debris in transmission fluid – Flaking or pitting on the gear faces sheds fine steel particles that contaminate the oil, visible during drain intervals as glitter-like sediment.
• Vibration at specific RPM ranges – Uneven wear on the planetary pinions creates harmonic vibrations felt through the chassis between 1800-2200 RPM.

Technical Specifications

Compatibility

This genuine ZF planetary gear is engineered specifically for the WG100, WG130, and WG131 transmission models. It also serves as a direct replacement in certain WG180 and WG200 variants when used with the corresponding 2095309059: DIFF.HOUSING and 0750117075: TAPER ROLLER BEARING. For dual-differential configurations, pairing this gear with the 2095209037: DIFFERENTIAL ensures proper backlash and torque distribution. Always verify your transmission serial number before ordering.
