ZF 1269.337.031 PLANETARY GEAR for WG65 | OEM Genuine Part

Overview

The ZF 1269.337.031 PLANETARY GEAR is a critical power-transfer component engineered specifically for the WG 65 Series transmission. This OEM genuine part sits within the planetary gearset assembly, where it manages torque distribution and speed reduction between the input shaft and the 4616105415: OUTPUT shaft. Precision-machined from high-strength alloy steel, the 1269.337.031 planetary gear ensures smooth, synchronized rotation under heavy loads. As an OEM genuine part, it guarantees exact fitment and durability, eliminating the risk of premature wear associated with aftermarket alternatives. The SKU 1269.337.031 is a direct replacement for the original factory-installed gear in WG65 transmissions.

Symptoms of Failure

When the ZF 1269.337.031 PLANETARY GEAR begins to wear, operators may notice several distinct failure indicators. Transmission gear slipping under load is a primary symptom, often accompanied by a grinding noise during acceleration. Metallic debris in the transmission fluid signals tooth surface fatigue or pitting on the planetary gear. Intermittent loss of drive power in forward gears, particularly at low RPM, points to worn gear teeth failing to engage properly with the 4616303144: OUTPUT FLANGE. Additionally, vibration through the driveline during steady-speed operation indicates uneven gear wear that can cascade into damage to the 4616101094: TRANSMISSION HOUSING if left unaddressed.

Technical Specifications

Compatibility

This planetary gear is designed for the ZF WG 65 Series transmission family. It is compatible with the following ZF models: WG65, WG80, WG120, WG150, WG180, and WG200 transmissions. The 1269.337.031 gear interfaces directly with the sun gear and ring gear assemblies in these units. For proper installation, ensure the 0636011038: HEXAGON SCREW is torqued to factory specifications to secure the gear carrier to the output shaft. Always verify your transmission serial number before ordering.
