6. Assembling the tail rotor head

(bag UM-11C)
Assemble the tail rotor head as shown in the drawing, greasing all bearings as you install them.
Place the two O-rings in the hub 4448.22 and press them into the channels. Oil the O-rings, fit
the tail rotor head on the tail rotor shaft, and line up the cross-hole in the shaft accurately with
the hole in the hub, and press the pin 4448.22 into place to fix the parts together. The pin is
secured in turn by fitting the M3 x 3 grubscrew.
Note the correct orientation of the hub, as shown in the drawing.
Fix the tail rotor blades in the blade holders using the two M3 x 20 screws. The tail rotor blade
fixing screws must not be over-tightened; the blades should just be free to swivel, so that they
can align themselves in the optimum position when they spin up to speed.
Note the orientation of the tail rotor blades: when viewed from the left-hand side, the tail rotor
rotates clockwise („bottom blade forward"); and the blade pitch arms on the blade holders must
be located in front of the blades.
