1.
Remove nuts (1, 2, and 3), washers (4, 5, 6, and
7), and bolts (8, 9, and 10) from swashplate (11)
and yoke (12).
Antiseize compound (E75) can form
toxic vapors if exposed to flame. Use
only with adequate ventilation, away
from open flame. In case of contact,
immediately flush skin or eyes with
water for at least 15 minutes. Get
medical attention for eyes.

Apply antiseize compound (E75) to bushing (13
and 14) on bolts (8 and 9). Keep compound off
threads of bolt. Wear gloves (E184.1).
FLIGHT SAFETY PARTS
This is an installation critical flight
safety part. All aspects of its assembly
and installation must be ensured at
each joint connection and mounting to
the swashplate and yoke assembly.
Ensure locking tab washer is facing in
the proper direction.
Ensure wire bundle is routed so as not
to interfere with flight control system
motions.
After applying nut torque, ensure
locking tab washer is lockwired to the
jam nut per BAC5018.
Ensure proper attaching hardware
(impedance type bolt, nut, and
washers) is installed including
verification of bolt head orientation,
torque, and installation of cotter pins.
Ensure special countersunk washers
are installed properly under the head
of self retaining bolts. Countersink
must face towards head of bolt.
Loose attachments within flight control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.
3.
Position rod end (15) of actuator (16) in
attachment lug (17) of swashplate (11). Actuator
motor (18) must face forward.
4.
Install bolt (8) head aft, through swashplate lug
(17) and actuator rod end (15). Install washer
(4) and nut (1). Torque nut to 400 to 660
inch-pounds. Install cotter pin (19).
5.
Have helper raise yoke (12). Align bearings of
actuator (16) and connecting link (20) in lugs of
swashplate (11) and yoke.
6.
Install bolt (9), head forward. Install washer
(5) and nut (2). Torque nut to 400 to 660
inch-pounds. Install cotter pin (21).
7.
Install washer (7) on bolt (10), recess toward
head. Install bolt (10) dry, head aft, washer
(6), and nut (3). Torque nut to 290 to 660
inch-pounds. Install cotter pin (22).
NOTE
Use additional washers, if needed,
to align cotter pin.
