Bevel Gear Mount for SX Helicopters Hirobo HI0404510  [HI0404510]

Bevel gear holder - product details

This bevel gear mount is supplied as a replacement for the Eagle, Freya, EX and SX model groups. It secures a bevel gear in the transmission stack, providing a repeatable mounting face for maintenance and modest tuning work on helicopter drivetrains.

The component is strictly a locating and support element: it positions the bevel gear relative to the gearbox, reduces axial and radial play, and offers a consistent reference for removal or inspection of gears. It ships as a single replacement part designed to fit the existing assembly without altering other drivetrain items.

Setup tips: after fitting, recheck gear mesh and runout, fasten associated screws to original torque levels, and manually spin the drivetrain to confirm smooth engagement. Use thin axial shims or standard shimming approaches to tweak backlash and ensure even gear contact.
