ZF 1269.298.901 PLANET GEAR SET for WG65 | OEM Genuine Part

Overview

The ZF 1269.298.901 PLANET GEAR SET is a critical torque-multiplying assembly within the WG 65 Series transmission. This OEM genuine component houses the planetary gears that distribute rotational force from the turbine shaft to the output carrier. The SKU 1269.298.901 is precision-engineered to handle high-load cycles, ensuring smooth power transfer during gear shifts. It sits directly between the 4616105415: OUTPUT shaft and the 4616303144: OUTPUT FLANGE, making it a central element in the drivetrain’s final drive assembly.

Symptoms of Failure

• Whining or grinding noise during acceleration: Worn planetary gears produce a distinct metallic whine, especially under load, indicating gear tooth surface fatigue.
• Erratic gear engagement or slipping: A failing planet gear set causes delayed or harsh shifts as the carrier loses its ability to maintain consistent mesh with the sun gear.
• Metallic debris in transmission fluid: Flakes or particles found during oil changes signal that the planet gears are shedding material, often accompanied by reduced hydraulic pressure.
• Vibration at highway speeds: Uneven wear on the planet gear bearings creates a rhythmic vibration that intensifies with RPM, felt through the chassis.

Technical Specifications

Compatibility

This planet gear set is engineered for the ZF WG 65 Series, specifically the WG65, WG80, and WG100 models. It is also compatible with the WG120 and WG150 transmissions when used with the correct 4616101094: TRANSMISSION HOUSING. Always verify the spline count and carrier width against your unit. The set integrates with the 0636011038: HEXAGON SCREW for secure mounting to the output shaft.
