Center Bearing Holder for Turbulence D3 Helicopters - Hirobo HI0414486  [HI0414486]

Turbulence D3 center bearing support component

The center bearing holder HI0414486 is intended for use on Turbulence D3 helicopters. The component secures the center bearing that supports the main drivetrain stack and helps keep the transmission geometry aligned in flight and during servicing.

Fitting is commonly carried out during a mid-frame or main shaft service cycle when bearings are inspected and replaced if worn. The holder's mechanical function is to locate the bearing, resist axial movement, and provide a defined mounting face so main and tail drive parts remain concentric.

When installing the holder, make sure the bearing seats fully and rotates freely before final tightening, avoid over-torquing the retaining screws, and verify the driveline runs smoothly after reassembly. Proper bearing positioning reduces play and gives more consistent tail and main drive response when tuning.
