Next, the main rotor shaft is connected to the main pulley 72Z. We recommend to put
a small amount of grease over the part of the shaft where the pulley will be mounted.
Slide the shaft with the drilling that is further away from the shaft end into the main
pulley so that it protrudes slightly past the pulley.
Make sure to tighten fast the main rotor shaft to the pulley with a M5 x 21,5 special
bolt
(B-S03)
and a hex nut M5
(B-S18)
. The nut is kept in place in the pulley by positive
locking.
Now connect the intermediate shaft to the tail pulley 48Z. Make sure that the tail pul-
ley is flush with the shaft end and that the grub screw M4 x 4
(B-S12)
is vertical to the
flat spot on the shaft. Using a small amount of lubricant may facilitate sliding the shaft
into the pulley.
