1.3 Preparing the main rotor shaft and bearings
(bag UM-1C)
Fix the swashplate guide 4618.113 to the dome bearing holder 4448.8 using two M2 x 12
cheesehead screws. Press a ballrace 4450.24 into the dome bearing holder and another into the
main rotor shaft bearing holder 4448.12 (grease the bearings).
Slide the circlip 4607.156 onto the main rotor shaft 4450.43 from the top end, and allow it to
snap into the channel; please note the following:
•
The circlip must not be over-stretched, i.e. don’t open it further than is absolutely necessary
to fit it on the main rotor shaft; use special circlip pliers if possible.
•
The inner face of the circlip features one rounded and one sharp edge; the sharp edge must
face up.
•
The circlip must be a firm fit on the shaft; it should not be possible to rotate it by hand.
