RIG COCKPIT TRANSFER BELLCRANKS
Impedance bolts are installed in flight
control connections. These bolts
are self-retaining and require special
torque and nut.
INSTALL TRANSFER BELLCRANK RIG PIN
Do not stand, kick, or induce lateral
loads to the thrust idler. A cracked
arm will cause in-flight failure resulting
in disconnecting the thrust cockpit
driver actuator (CCDA) and the
droop eliminator potentiometers
(Without 74 ) or thrust control position
transducer (With 74 ).
Install transfer bellcrank rig pin (T128) (1) through
structure (2), four bellcranks (3, 4, 5, and 6) and
structure (7). Pin must slide freely. If free, go to
step 11. If not, perform steps 2 thru 11.
