ZF 4699.801.176 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.176 GK10 is a precision-engineered gear kit designed for heavy-duty construction machinery transmissions. This OEM genuine part functions as the primary power transfer assembly within the planetary gear set, converting input torque into controlled rotational force for the final drive. The SKU 4699.801.176 specifically identifies the GK10 variant, which is critical for maintaining gear ratio integrity in ZF drivelines. When installed alongside the 4699001176: GK10, this component ensures synchronized engagement between the input shaft and output hub. Its location within the transmission housing makes it a central element for load distribution under high-stress operating conditions.

Symptoms of Failure

• Erratic gear engagement – Worn teeth on the 4699.801.176 cause delayed or harsh shifting, particularly when transitioning between forward and reverse in loaders or excavators.
• Metallic grinding noise – A high-pitched whine or grinding sound during acceleration indicates pitting or chipping on the gear surfaces, often accompanied by debris in the transmission fluid.
• Oil contamination – Internal wear generates metallic particles that bypass the filter, leading to sludge buildup and reduced hydraulic pressure. This is a common long-tail search query for “ZF transmission metal shavings in oil.”
• Torque loss under load – The machine struggles to maintain speed on inclines or during heavy digging, signaling that the GK10 is slipping within the planetary carrier.

Technical Specifications

Compatibility

This GK10 gear kit is engineered for ZF WG180, WG200, and WG211 series transmissions commonly used in telescopic handlers, wheel loaders, and mobile cranes. It directly replaces the original equipment part in models such as the ZF 4WG-180, 4WG-200, and 5WG-211. For complete assembly, pair it with the 4699101095: HOUSING to ensure proper alignment, and verify that the 4699102158: INPUT shaft splines match the gear bore. The 4699103063: OUTPUT flange must also be inspected for wear when replacing this part.
