1.6 Installing the gyro platform
(bag UM-7)
Fix the gyro platform holder 4450.16 to the side frames using 2.2 x 9.5 self-tapping screws. Fit
the gyro platform 1291.12 on top, and secure it with four 2.2 x 6.5 self-tapping screws.
1.7 Collective pitch compensator and swashplate
(bag U2-8)
The collective pitch compensator 4618.147 is assembled as shown in the illustration.
Start by fitting a circlip on each of the brass pins, and glue them in the holes in the collective
pitch compensator centre piece 4618.46 using bearing retainer fluid, with the circlips located
fully in the recesses. Press the ballraces 4618.129 in the arms of the collective pitch
compensator and slip them on the projecting ends of the brass pins, fitting at least one shim
washer between the centre piece and the arm on each side; check that the arms are free to
rotate on the pins. Fit the outer circlips to retain the arms, and check that there is no axial play
present in the arms on the pins. If there is detectable slop, fit additional shim washers to take it
up.
