ZF 4699.808.047 GK16 | OEM Genuine Part

Overview

The ZF 4699.808.047 GK16 is a precision-engineered gear set assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part sits within the planetary gear train of ZF’s modular transmission systems, where it manages torque distribution and speed reduction during high-load operations. The SKU 4699.808.047 is critical for maintaining proper gear mesh alignment and load-bearing capacity in excavators, wheel loaders, and graders. When paired with the 4699008047: GK16 companion component, this assembly ensures synchronized power flow from the input shaft to the output shaft.

Symptoms of Failure

• Intermittent gear slipping under load – Worn teeth on the 4699.808.047 cause momentary loss of torque transfer, especially when climbing grades or lifting heavy materials.
• Metallic grinding noise during shifting – Deteriorated bearing surfaces within the GK16 assembly produce a distinct scraping sound that intensifies with transmission temperature.
• Hydraulic oil contamination with metal particles – Flaking gear material enters the lubrication system, visible as glitter in oil samples during routine maintenance.
• Delayed engagement from neutral to drive – Excessive clearance in the gear set prevents immediate clutch pack engagement, creating a 2-3 second lag.

Technical Specifications

Compatibility

This GK16 gear set is engineered for ZF WG180, WG200, and WG210 series transmissions commonly used in construction machinery. It directly replaces the original equipment in 4699101093: HOUSING assemblies and interfaces with the 4699102142: INPUT shaft and 4699103054: OUTPUT shaft. Compatible models include ZF 4WG180, 5WG200, and 6WG210 variants found in Volvo, Caterpillar, and Komatsu equipment.
