Hirobo HI0404314 Gear with Shaft for Eagle, Freya, EX, SX Helicopters  [HI0404314]

Direct replacement gear and shaft for Hirobo models

This Hirobo HI0404314 gear with shaft is a scale replacement part intended for routine helicopter maintenance and repair. It fits into the drivetrain to transfer torque between gear stages and is used to correct worn mesh and axial misalignment after impact or long service.

Compatibility is stated for Eagle, Freya, EX and SX model series within Hirobo helicopter parts; always confirm the exact model fit prior to installation. The component serves as a mechanical link inside the rotor drivetrain and is not a bearing or motor part.

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

Packaging normally contains the single gear with shaft; verify 1 pcs on arrival and confirm orientation during assembly.
