(c) Move the rod end [5] from the autothrottle brake assembly clevis.
(d) Move the autothrottle brake assembly clevis to get the correct TRA value on the FMCS
CDU.
(e) Make sure they are in these limits:
1) POSITION CH A indication reads 36.0 ±0.8 degree.
2) POSITION CH B indication reads 36.0 ±0.8 degree.
3) The difference between the TRA POSITION CH A and the TRA POSITION CH B
should be less than 0.8 degree.
(f) Loosen the jamnut [6] and turn the rod end [5] to align it with the autothrottle brake
assembly clevis.
NOTE: Use the bolt [4] to make sure that the parts are aligned.
1) Insert the bolt [4] with the bolt head on the inboard side of the autothrottle brake
assembly.
2) Install the washer [3], the nut [2], and a new cotter pin [1].
3) Tighten the jamnut [6] on the control rod to 95 in-lb (10.7 N·m) – 160 in-lb
(18.1 N·m).
(g) Make sure that the POSITION CH A and POSITION CH B indications on the CDU still
read 36.0 ±0.8 degrees, and the difference is less than 0.8 degree.
1) If the values are not in the specified range, adjust the thrust control rod until you get
the correct values.
SUBTASK 76-11-05-820-003-F00
(2) Do a check of the adjustment as follows:
(a) Carefully move the thrust lever to the full forward thrust position.
1) Stop for a minimum of 2 seconds.
2) Make sure that the POSITION CH A and POSITION CH B indications on the FMCS
CDU read 84.0 ±1.8 degrees.
3) If the values are not in the specified range, adjust the thrust control rod again until
you get the correct value.
