ZF 4699.808.051 GK16 | OEM Genuine Part

Overview

The ZF 4699.808.051 GK16 is a precision-engineered clutch pack assembly designed for the high-torque demands of construction machinery transmissions. Positioned within the planetary gearset, this OEM genuine part controls hydraulic pressure to engage specific gear ratios, ensuring smooth power delivery from the engine to the driveline. The SKU 4699.808.051 is a direct replacement for the original factory component, guaranteeing exact fitment and durability under heavy loads. When paired with the 4699008048: GK16 assembly, it forms the core shifting mechanism for ZF power shift transmissions.

Symptoms of Failure

• Delayed or harsh gear engagement – Worn friction discs cause hesitation when shifting from neutral to drive, a common sign of internal clutch pack degradation.
• Transmission fluid leaks near the housing – Deteriorated seals allow oil to escape, often visible around the 4699101107: HOUSING interface.
• Gear slipping under load – When the clutch pack fails to hold pressure, the transmission loses torque transfer, especially during uphill operation or heavy digging.
• Burning smell from overheated oil – Friction material wear generates excessive heat, leading to fluid breakdown and a distinct burnt odor.

Technical Specifications

Compatibility

This GK16 clutch pack is engineered for ZF WG series transmissions commonly used in wheel loaders, excavators, and telehandlers. It directly fits the WG180, WG200, and WG210 models. For complete rebuilds, verify the condition of the 4699102163: INPUT shaft and 4699103113: OUTPUT flange, as worn splines can damage the new clutch pack. Always replace seals and snap rings during installation.
