ZF 4699.001.200 GK10 | OEM Genuine Part

Overview

The ZF 4699.001.200 GK10 is a precision-engineered OEM genuine gear set designed for heavy-duty construction machinery transmissions. This component functions as a primary reduction gear within the planetary gear train, converting high-speed input torque into usable low-speed, high-torque output for demanding off-road applications. The SKU 4699.001.200 is a critical wear item that directly influences shift quality and power delivery. It interfaces directly with the HOUSING and the INPUT shaft assembly, ensuring precise gear mesh alignment under extreme loads.

Symptoms of Failure

• Grinding or whining noise during gear engagement: Worn teeth on the 4699.001.200 produce a distinct metallic sound, especially when shifting from neutral to drive under load.
• Intermittent gear slippage under heavy load: As the gear set loses tooth profile integrity, the transmission may momentarily lose power transfer when climbing grades or lifting heavy loads.
• Metallic debris in transmission fluid: Flakes or particles found during oil changes indicate advanced wear of the GK10 gear set, often accompanied by a burnt smell.
• Delayed or harsh shifting: Worn gear teeth cause improper synchronization between the OUTPUT shaft and planetary carrier, leading to jarring shifts.

Technical Specifications

Compatibility

This genuine ZF gear set is engineered for use in the following transmission models commonly found in wheel loaders, excavators, and telehandlers: ZF WG180, ZF WG200, ZF WG210, and ZF 4WG200. It is also compatible with select ZF Ergopower and ZF Ecomix series transmissions used in concrete mixers. Always verify the HOUSING COVER part number for correct fitment, as variations exist between early and late production runs.
