Hirobo HI0404510 Precision SX Bevel Gear Holder (for Eagle/Freya/EX/SX)  [HI0404510]

Overview of SX bevel gear mount

This item is a precision replacement bevel gear holder for models grouped under Eagle, Freya, EX and SX. It is designed to secure bevel gears in the transmission assembly and assist routine service or minor tuning tasks on helicopter drivetrains.

As a structural component, the holder locates the bevel gear relative to the gearbox and drive components, helping to limit axial and radial movement while providing a consistent reference when replacing or inspecting gears. It is supplied as a single spare and installs into the existing gearbox arrangement without modifying other drivetrain parts.

Fitting pointers: verify mesh and runout after installation, tighten related fasteners to their specified torque, and check gear engagement by hand rotation prior to powering the model. Fine adjustments to backlash are commonly made with small axial shims or standard shimming methods.
