Hirobo HI0403240 Mechanical Interface Plate for GPH 346  [HI0403240]

Mechanical interface for GPH 346 assemblies

This Hirobo HI0403240 mechanical plate is an RC-scale replacement part intended for use with assemblies that reference GPH 346 in their parts lists. The plate operates as a mounting interface inside the helicopter drivetrain area, providing a stable platform for neighbouring components and helping to maintain consistent gear and shaft alignment during operation.

Prioritise precise alignment and sound hardware practice when fitting this plate instead of seeking handling changes. Fit to the original mounting points with correct fasteners, confirm shaft concentricity, and verify clearances around moving parts before flight. Minor misalignment at the mounting plane can influence rotor or tail gear behaviour, so secure the plate evenly and recheck alignment after tightening.

Inspect the plate regularly for cracks, bending, or wear at mounting holes following heavy impacts or long service periods. Clean contact faces and ensure adjacent bearings and gears sit flush to minimise play and maintain predictable control. The component is supplied and described as an RC accessory sized for model helicopters.
