20T Bevel Gear with Shaft — Fitment and Tuning for Eagle Freya

The Hirobo HI0414177 item is a bevel gear assembly supplied with its shaft, designed for installation in Eagle Freya helicopter drivetrains. It replaces the original bevel gear to restore the correct interface between gearbox components and the bevel gear set.

Fitting tips: ensure the shaft seats properly and that axial clearance is correct before final fastener torque. Verify gear mesh at low throttle and confirm all adjacent bearings rotate without binding. Only use thread locker where your kit manual specifies, and avoid over-tightening which can change bearing preload and gear alignment.

Tuning impact: installing this replacement allows you to precisely set gear mesh for reduced noise and improved drivetrain efficiency. Check the mating pinion and nearby bearings during installation to identify any secondary wear that might affect performance.
