4. Procedure
Subtask 76-11-00-820-051-A ** ON A/C NOT FOR ALL

A. Adjustment of the Artificial Feel Unit:
(1) Loosen the three screws (3). Remove the guard (7).
(2) Cut and remove the lockwire from the lock nut (6). Loosen the lock nut.
(3) Hold the adjusting rod (5) then turn the nut (4) to get a load of between 0.85 and 1.05 daN to move the throttle control lever between the IDLE STOP and the MAX CLIMB.

NOTE: Measure this value in the IDLE STOP/MAX CLIMB range. Do not measure this value at the detent points where the load increases suddenly.

(4) Tighten the lock nut (6) to block the adjustment system. Measure the load again to make sure that it is the same.
(5) Safety the lock nut (6) with corrosion resistant steel lockwire 0.8 mm dia (0.032 in.)
(6) Install the guard (7). Tighten the three screws (3).
(7) Cut and remove the lockwire from the lock nut (2). Loosen the lock nut.
(8) Turn the adjustment screw (1) to get a break-out force of 2.5 +0.1 -0 daN (5.62 +0.22 -0 lbf) when you go through the MAX CLIMB detent point (the first detent point that you feel when you move the lever forward).

NOTE: This hard point includes the load measured in step (3).

(9) Block the adjustment system. Measure the load again to make sure that it is the same as the value given in the step (8).
(10) Safety the lock nut (2) with corrosion resistant steel lockwire 0.8 mm dia (0.032 in.)
