ZF 2094.311.054 PLANETARY GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.311.054 PLANETARY GEAR is a critical power-transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as the central gear element within the planetary gearset, directly managing torque distribution and speed reduction between the input shaft and the output assembly. The SKU 2094.311.054 is precision-machined to interface seamlessly with the 2094101012: TRANSMISSION HOUSING, ensuring concentric alignment and load-bearing stability. It sits within the main gear train, converting high-speed rotational input into usable mechanical advantage for heavy-duty industrial applications.

Symptoms of Failure

• Erratic gear slipping under load – When the planetary gear teeth wear or spall, the transmission may lose torque capacity, causing sudden slips during acceleration or uphill operation.
• Metallic grinding or whining noise – Worn bearing surfaces or fractured gear teeth produce distinct high-pitched sounds, especially at low speeds or during gear changes.
• Oil contamination with metallic debris – As the gear degrades, fine metal particles enter the lubricant, visible during oil changes as glitter-like sediment.
• Vibration and driveline shudder – Uneven wear on the planetary gear set leads to rotational imbalance, felt as rhythmic shaking through the chassis.

Technical Specifications

Compatibility

This planetary gear is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct 2094301036: HOUSING and 2094298057: HOUSING. For complete assembly, the 2094301071: COVER must be installed to seal the gear cavity. Always verify your transmission model and serial number before ordering.
