ZF 4699.801.134 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.134 GK10 is a genuine OEM gearset assembly engineered for the high-torque planetary sections of ZF heavy-duty construction machinery transmissions. This component, identified by SKU 4699.801.134, functions as the primary power transfer unit within the gearbox, converting rotational force from the input shaft into the correct ratio for the output drive. It sits directly inside the main HOUSING, where it meshes with the planetary carrier to deliver smooth, reliable power under extreme loads. As an OEM part, it guarantees exact tolerances and metallurgical composition, ensuring longevity in demanding environments like wheel loaders and dump trucks.

Symptoms of Failure

When the ZF 4699.801.134 GK10 begins to wear, operators often notice distinct performance issues. Gear slipping under load is a primary indicator, where the transmission momentarily loses drive torque during acceleration or climbing. Metallic grinding noises from the transmission housing typically signal damaged gear teeth or bearing surfaces within the GK10 assembly. Contaminated transmission fluid with visible metal particles is another critical symptom, pointing to internal wear of the gearset. Additionally, erratic shifting or delayed engagement can occur as the worn gearset fails to maintain proper hydraulic pressure in the clutch packs.

Technical Specifications

Compatibility

This genuine GK10 gearset is designed for integration into ZF WG series transmissions commonly used in construction machinery. It is a direct fit for the WG180 and WG200 series, as well as the WG150 and WG250 models. The part also appears in certain Ecomat 4HP and 6HP variants where planetary gear reduction is required. For proper sealing during installation, always replace the O-RING and ensure the HOUSING COVER is free of debris. The BREATHER should also be inspected to prevent pressure buildup that could damage the gearset.
