Replacement Gear and Shaft for Hirobo Eagle Freya EX SX - HI0404314  [HI0404314]

Drive gear shaft replacement for Hirobo helis

This Hirobo HI0404314 gear with shaft is intended as a direct replacement component for helicopter drivetrain maintenance. It acts within the transmission to pass torque between stages and to reestablish proper gear engagement after wear or impact.

The item is compatible with Eagle, Freya, EX and SX model series from Hirobo; verify the specific model fit prior to installation. It is a drivetrain element rather than a bearing or motor assembly.

Installation notes: check mating gears and shaft bores for wear, remove contaminants, and confirm correct mesh and axial play before final tightening. For tuning, small axial adjustments and shim changes can reduce vibration and improve efficiency; do not press the shaft forcefully to avoid damage.

Package contents typically include the single gear with shaft assembly; confirm 1 pcs in the box and the correct orientation when fitting.
