6.4 ROTOR CASE ASSEMBLY
Before installing the rotor case (31) to the gearbox (1A), make sure to clean the surface of the
rotor case and the Gearbox and make sure to put the shims between rotor case and Gearbox as
originally.
Assemble the rotor case (31) onto the Gearbox (1A) and secure
the four hexa-nuts (46) with reference of below torque set
value.

To tighten the second rotor, place the plastic bar on the opposite
side of the rotor and tighten the second rotor bolt to the proper
torque.
Be sure not to make any bur on the rotor bolt groove during this process. It may cause a serious
problem such as galling on the rotor case and if it happened, it must be removed.
Install the new O-ring inside of the cover (32) and slide the
cover over the studs. Screw the cap nuts (33) on the studs and
tighten using an appropriate wrench with reference of below
torque set value in an opposing manner shown in Figure 25.
