Hirobo HI0414486 Center Bearing Mount for Turbulence D3  [HI0414486]

Center bearing mount for Turbulence D3 airframes

This center bearing mount fits Turbulence D3 RC helicopters and secures the central bearing that supports the primary drivetrain. The part helps maintain correct transmission geometry during both service and flight operations.

Installation is typically performed as part of a main-shaft or mid-frame service cycle when bearings are inspected and replaced if necessary. The mount locates the bearing, resists axial movement, and provides a precise seating surface so the main and tail drive components stay concentric.

When fitting this mount, confirm bearing seating and axial clearance before final assembly, avoid over-tightening retaining screws, and spin the driveline to confirm smooth operation. Accurate bearing placement can reduce play and stabilise tail and main drive response during tuning.
