1.8 Collective pitch compensator
(bag J2-1)
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 compen-
sator 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.
Fit the collective pitch compensator on the main rotor shaft, and press the two ball-links onto the
appropriate balls on the inner ring of the swashplate, as shown in the illustration.
