Micro Star 400
Reverse the whole procedure to install the new main rotor shaft.
When tightening the annular clamps use this procedure: first fit the clamp (o), positioned flush
with the bottom edge of the main rotor shaft (p). Follow this with clamp (n), pushing it down
whilst pulling the main rotor shaft up; this eliminates any axial play. Finally tighten the annular
clamp (m), pushing it down against the bearing.
