1.3 Preparing the main rotor shaft and bearings
Fix the swashplate guide 4618.113 to the dome bearing holder 4448.8 using two M2 x 12
cheesehead screws. Press one of the ballraces 4450.24 into the dome bearing holder, and one
into the main rotor shaft bearing holder 4448.12; grease both bearings.
The next step is to slide the circlip 4607.156 along the main rotor shaft 4450.43 from the top,
and allow it to engage in the channel. Please note the following points here:
• The circlip must not be over-stressed, i.e. take care not to open it further than absolutely
necessary in order to slide it onto the main rotor shaft. Special circlip pliers are the best tool
for this job.
• The inner face of the circlip features one rounded and one sharp edge; the sharp side must
face up.
• The circlip must be a really tight fit on the shaft; it should not be possible to rotate it by hand.
