Hirobo HI0404314 gear with shaft replacement for Eagle Freya EX SX helicopters  [HI0404314]

Replacement gear with shaft for Hirobo helis

This HIROBO HI0404314 gear with shaft is an RC-scale replacement part intended for common helicopter maintenance and repair. It serves as a direct drivetrain component that transfers power between stages; use it to restore gear mesh and shaft alignment after wear or impact.

Compatibility is with Eagle, Freya, EX and SX model series classified under common Hirobo helicopter parts; verify model fit before installation. The part functions as a mechanical link inside the rotor drivetrain and is not a bearing or motor component.

Installation notes: inspect existing mating gears and shaft bores for wear, clean contact surfaces, and confirm correct mesh and axial play before final assembly. When tuning, small axial adjustments and shim changes can reduce noise and improve transmission efficiency; avoid forcing the shaft to prevent scoring.

Packaging typically contains the single gear assembly ready for fitment, check for 1 pcs in the package and confirm orientation during installation.
