ZF 4699.801.135 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.135 GK10 is a genuine OEM gear set assembly engineered for heavy-duty construction machinery transmissions. This SKU 4699.801.135 functions as the primary reduction gear cluster within the planetary gear train, directly managing torque distribution from the input shaft to the output shaft. Designed to withstand extreme loads in excavators, wheel loaders, and dozers, the GK10 assembly ensures precise gear meshing and minimal backlash under high-stress conditions. It is a critical component that works in tandem with the 4699101080: HOUSING to maintain structural alignment and oil flow within the transmission housing.

Symptoms of Failure

When the ZF 4699.801.135 GK10 begins to wear, operators often notice intermittent gear slipping under load, particularly during uphill travel or heavy digging cycles. A second common failure sign is metallic grinding noises from the transmission sump, indicating pitting or spalling on the gear teeth. You may also observe erratic shift engagement where the transmission hesitates or clunks harshly when moving between forward and reverse. Finally, contaminated transmission fluid with visible metal particles is a clear indicator that this gear set requires immediate replacement to prevent cascading damage to the 0501329881: HOUSING COVER and adjacent bearings.

Technical Specifications

Compatibility

This genuine GK10 gear set is specifically designed for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in construction machinery. It also fits select variants of the ZF 4WG-200 and 6WG-200 models used in articulated dump trucks and graders. For proper installation, ensure the 0630513065: SNAP RING is correctly seated to secure the gear cluster axially. Additionally, always replace the 0634306309: O-RING during reassembly to prevent fluid bypass between the gear set and the housing bore.
