ZF 4699.801.202 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.202 GK10 is a precision-engineered gear cluster assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part functions as a primary power transfer component within the planetary gear set, converting rotational input from the torque converter into usable torque for the driveline. The SKU 4699.801.202 sits directly within the intermediate shaft assembly of ZF’s modular transmission architecture, where it meshes with the 4699001202: GK10 companion gear to manage load distribution under extreme operating conditions. Manufactured from case-hardened alloy steel, this component ensures minimal backlash and sustained performance in excavators, wheel loaders, and graders.

Symptoms of Failure

When the ZF 4699.801.202 gear cluster begins to degrade, operators typically notice intermittent gear slipping under load during excavation or grading cycles. A second common indicator is metallic grinding noises from the transmission housing, particularly when shifting between forward and reverse ranges. Third, contaminated transmission fluid with visible metal particles often appears during routine oil changes, signaling advanced wear on the gear teeth. Finally, erratic engagement of the PTO or wheel drive may occur, especially when the 4699101125: HOUSING alignment shifts due to bearing failure.

Technical Specifications

Compatibility

This ZF 4699.801.202 GK10 gear cluster is engineered for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG211, and WG250 series. It also integrates with the 4699102156: INPUT shaft assembly and the 4699103016: OUTPUT flange in 4-speed powershift configurations. For optimal sealing and retention, always pair this gear with the 0634306309: O-RING and 0630513065: SNAP RING during rebuilds.
