COLLECTIVE SERVOCYLINDER ROD END REPLACEMENT continued
Distance between center of rod end
bore and top of piston shall not ex-
ceed 3.06 INCHES. A measurement
less than 3.06 INCHES is necessary to
provide enough thread engagement to
maintain safe flight. Failure to follow
maintenance instructions may result
in serious injury or death of
crewmembers and/or serious damage
to the helicopter.
To prevent breakdown of cylinder piston
rings, rotation of piston rod is limited to
45 DEGREES so that rod end can be
alined with bellcrank during rigging and
installation. Adjustments are made by
turning rod end, not piston rod.
c. Install rod end (1), with nut (10) and lock (11),
on piston rod (9).
(1) Hold piston rod (9). Use crowfoot.
(2) Screw rod end (1), with nut (10) and lock (11),
into piston rod (9).
(3) Adjust rod end (1) so distance A between
center of rod end bore (8) and top of piston
rod (9) is within 0.016 INCH of the measure-
ment recorded in paragraph 7.43.3.
