ZF 4699.801.084 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.084 GK10 is a critical OEM genuine assembly component designed for heavy-duty construction machinery transmissions. This part functions as a key structural and operational element within the gear cluster, ensuring precise alignment and torque transfer under extreme loads. Specifically, the GK10 assembly interfaces directly with the main shaft and planetary gear sets to maintain driveline integrity. The SKU 4699.801.084 is engineered to ZF’s exacting tolerances, making it essential for maintaining factory-specified performance in excavators, wheel loaders, and graders. When installed alongside the 4699101080 HOUSING and the 0501329881 HOUSING COVER, this part forms a sealed, high-pressure unit that prevents contamination and lubricant loss.

Symptoms of Failure

When the ZF 4699.801.084 GK10 begins to wear, operators will notice distinct operational issues. Common failure symptoms include:

• Intermittent gear slipping under load: The GK10 assembly loses its clamping force, causing the transmission to momentarily lose power during excavation or grading.
• Metallic grinding noises from the bell housing: Worn internal surfaces create audible friction, often mistaken for bearing failure.
• Hydraulic fluid contamination: Debris from the failing GK10 enters the oil circuit, leading to premature wear of the 0634306309 O-RING and seals.
• Erratic shift timing: The transmission control module detects abnormal resistance, triggering fault codes and harsh engagements.

Technical Specifications

Compatibility

This OEM genuine GK10 part is engineered for ZF’s WG series powershift transmissions commonly used in construction machinery. Verified compatible models include:

• ZF WG180 (6-speed, off-highway)
• ZF WG200 (8-speed, heavy-duty)
• ZF WG211 (with integrated torque converter)
• ZF WG310 (high-torque variants for wheel loaders)

Always verify the 0630513065 SNAP RING condition during installation, as this retaining ring secures the GK10 in the housing bore. For complete assembly, pair with the 4699001084 GK10 variant if your system requires a different spline profile.
