The Hirobo HI0404314 gear with shaft is a replacement drivetrain component designed for helicopter maintenance and repair tasks. It transmits power between gear stages and is used to restore correct engagement and axial positioning following wear or impact.
Compatibility covers Eagle, Freya, EX and SX model series within the Hirobo parts catalogue; always check the precise model before fitting. This item is a mechanical transmission part and does not include bearings or motors.
Installation advice: inspect matching gears and shaft bores for signs of wear, clean mating surfaces, and set correct mesh and axial play before securing. Fine axial adjustments and thin shims can improve smoothness; avoid forcing the shaft to prevent scoring of the bore or shaft.
Typical packaging contains the single gear assembly ready for installation; confirm the package includes 1 pcs and that the orientation is correct when assembling.
