ZF 4699.801.227 GK10LD | OEM Genuine Part

Overview

The ZF 4699.801.227 GK10LD is a precision-engineered gear assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part functions as a critical power transfer component within the planetary gear set, converting rotational force from the input shaft to the output shaft while maintaining torque efficiency. The SKU 4699.801.227 is specifically calibrated for ZF’s modular transmission architecture, ensuring seamless integration with the clutch pack and housing assembly. When paired with the 4699001185 GK10LD gear kit, this part delivers consistent performance under extreme load conditions.

Symptoms of Failure

• Delayed engagement or gear slipping – Worn teeth on the 4699.801.227 cause hesitation when shifting from neutral to drive, often accompanied by a grinding noise during acceleration.
• Metallic debris in transmission fluid – Flaking or pitting on the gear surface produces fine metal particles visible during oil changes, indicating imminent failure of the GK10LD assembly.
• Vibration at low RPM – Uneven wear on the gear teeth creates harmonic oscillations felt through the chassis, particularly when operating under 1,500 RPM in construction equipment.
• Oil leaks near the housing interface – Cracks in the gear hub or seal degradation allow hydraulic fluid to escape, leaving visible residue around the 4699101108 HOUSING connection point.

Technical Specifications

Compatibility

This GK10LD gear is engineered for ZF’s WG180, WG200, and WG210 transmission series commonly found in wheel loaders, excavators, and telescopic handlers. It directly interfaces with the 4699102172 INPUT shaft and the 4699103057 OUTPUT flange. The 4699.801.227 is also compatible with ZF’s 4WG-200 and 6WG-200 variants used in Caterpillar, Volvo, and Komatsu construction machinery. Always verify the transmission serial number before installation.
