ZF 4699.001.193 GK10 | OEM Genuine Part

Overview

The ZF 4699.001.193 GK10 is a genuine OEM gear set assembly engineered for high-torque planetary transmissions used in construction machinery. This critical internal component transfers rotational force from the input shaft to the output carrier, enabling precise speed reduction and torque multiplication within the transmission housing. The SKU 4699.001.193 is designed to interface directly with the 4699101081 HOUSING and the 0501329881 HOUSING COVER, forming the core of the gear train. As a genuine ZF part, it ensures exact tooth geometry and metallurgical integrity for demanding off-highway applications.

Symptoms of Failure

• Erratic gear engagement or slipping under load – Worn gear teeth on the GK10 set lose their hardened profile, causing intermittent power loss during excavation or grading operations.
• Metallic grinding noise from the transmission – Pitting or spalling on the gear flanks produces a distinct whining or grinding sound, especially during directional shifts.
• Oil contamination with metallic debris – As the gear set degrades, fine steel particles circulate through the system, often clogging the 0634306309 O-RING seals and accelerating wear on adjacent components.
• Reduced hydraulic pressure in the clutch packs – A failing gear set can cause internal leakage paths, leading to soft shifts and eventual transmission overheating.

Technical Specifications

Compatibility

This genuine GK10 gear set is primarily used in ZF WG180, WG200, and WG211 series transmissions found in wheel loaders, excavators, and telehandlers. It also fits select variants of the ZF 4WG-200 and 6WG-200 powershift models. The gear set works in conjunction with the 0637885612 BREATHER to equalize internal pressure and prevent moisture ingress. For complete assembly, verify compatibility with your specific transmission serial number.
