Eagle/Freya/EX/SX Bevel Gear Mounting Holder - Hirobo HI0404510  [HI0404510]

Mounting holder overview for SX

This replacement bevel gear holder fits models classified under Eagle, Freya, EX and SX. It is built to locate and support the bevel gear inside the gearbox, aiding routine maintenance and inspection tasks on helicopter drivetrains.

The item acts purely as a structural locating piece: it sets the bevel gear relative to the gearbox and drive elements, helps control axial and radial movement, and ensures a repeatable reference when gears are removed or refitted. It is provided as a single spare designed to drop into the existing drivetrain setup without modifying adjacent parts.

Fitting advice: after installing the holder, verify gear mesh and check for runout, tighten screws back to their specified torque, and rotate the drivetrain by hand to ensure smooth engagement before powered operation. Typical shimming methods can be applied to adjust backlash and optimise gear contact.
