Slide the spacer
0407
on the rotor shaft down to the upper bearing, but do not install the swashplate.
Slide the rotor head on the rotor shaft temporary down until it stops at the bushing. Press the main gear in the mechanics
upwards as far as possible. Align the hole of the center piece of the rotor head with the hole of the rotor shaft by tilting the
rotor head. Put in the high strength M4x24 shaft screw
0136
through the hole without tightening.
Move the main gear up and downwards to check the size of the play.
Attention!
You will find a bag with additional shim rings 12x18x 0,1 / 0,2 / 0,3 in the bag of the rotor shaft unit.
You can eliminate the axial play with these shims when necessary by putting them between the spacer and the upper
rotor shaft bearing (
see red arrow
, right picture). You can eliminate a play from 0,1 to 0,6 by using different combinations
of the three shims.
To prevent from dismounting the rotor head each time you can put the shims between the spacer and the bearing from
the side until you investigated the right total shim thickness. After that you can remove the rotor head and the spacer and
place the shims finally under the spacer.
Position the swash plate and the rotor head and tilt the shaft screw tight. Use M4 lock nut and two M4 washers
respectively.
Grease the spacer on the outer surface with Dry Fluid Gear to get a smooth sliding swashplate.
Attention!
To clamp the center piece of the rotor head additionally to the rotor shaft tilt the two M3x14 Allen screws
alternating step by step.
Finally press the control rods (assembled in the first assembly group) onto the ball pins. The characters (2,5) should be
on the outside to reduce the necessary force for pressing.
Fix the control rod first at the rotor head and then at the swashplate to allow the sliding of the rod into the crank of the
center piece. When removing the control rod proceed vice versa which means first at the swashplate then at the rotor
head. When adjusting the rod just loose it at the swashplate.
