Bushings must be in bellcranks before
installing bolts; otherwise, damage to
components will result.
NOTE
Impedance bolts are installed in flight
control connections. These bolts are
self-retaining and require a special
nut and torque (Task 1-13).
1.
If connecting link (1) is a replacement, loosen nut
(2). Turn rod end (3) 90º to rod end (4). Torque
nut (2) to 350 inch-pounds.
2.
Remove nut (5), two washers (6 and 7), and bolt
(8) from bellcrank (9).
3.
Insert rod end (3) of link (1) aft through hole (10)
in structure.
NOTE
Adjustable end (3) is connected as
shown to bellcrank (9), when possible
the adjustable ends should be aft or
up.
4.
Position link (1) in bellcrank (9). Install bolt (8),
two washers (7 and 6), and nut (5) in bellcrank.
5.
Remove nut (11), two washers (12 and 13), and
bolt (14) from bellcrank (15).
6.
Position link (1) in bellcrank (15). Install bolt
(14), two washers (13 and 12), and nut (11) in
bellcrank.
7.
Torque two nuts (5 and 11) to 60 to 90
inch-pounds. Install two cotter pins (16 and 17).
8.
Check two bolts (8 and 14). Bolts shall not rotate
with torque less than 10 inch-pounds. There
shall be no axial looseness. If bolt rotates or is
loose, add washer under nut and repeat step 7.
NOTE
If connecting links are changed in
length perform neutral rig check (Task
11-33).
