ZF 4699.801.082 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.082 GK10 is a precision-engineered gear set assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part serves as the primary power transfer component within the planetary gear train, converting engine torque into usable wheel speed. The SKU 4699.801.082 sits directly within the main transmission housing, interfacing with the 4699101080 HOUSING to ensure concentric alignment and load distribution. As a critical wear item, this GK10 assembly must maintain exacting tolerances to prevent drivetrain inefficiency in excavators, wheel loaders, and graders.

Symptoms of Failure

• Erratic gear engagement or slipping under load – Worn gear teeth on the 4699.801.082 cause intermittent power loss during digging or lifting operations, a common search query for “ZF transmission slipping under heavy load.”
• Metallic grinding noise from the transmission – Pitting or spalling on the gear faces produces a distinct whining or grinding sound, often searched as “construction machinery transmission noise when accelerating.”
• Contaminated transmission fluid with metal particles – As the GK10 degrades, microscopic steel fragments enter the oil, detectable during routine fluid changes. This symptom aligns with “metal shavings in ZF transmission oil.”
• Vibration through the chassis during operation – Uneven tooth wear creates harmonic vibrations, particularly at specific RPM ranges, leading to searches like “ZF gearbox vibration in wheel loader.”

Technical Specifications

Compatibility

This GK10 gear set is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It is directly compatible with the WG180, WG200, and WG250 models. The part also integrates with the 0501329881 HOUSING COVER to seal the gear cavity, while the 0630513065 SNAP RING secures axial positioning. For hydraulic sealing, the 0634306309 O-RING prevents fluid bypass between the gear and housing interfaces. Additional fitment includes select ZF 4WG and 6WG series transmissions used in Caterpillar, Volvo, and Komatsu equipment.
