(1) If you install a new forward cable, you must apply a pre-tension to the cable before you adjust it.
-In theory, the pre-tension time is 48 hours without movement of the aircraft. After this pre-tension time the adjustment of the cable will stay correct.
-A minimum pre-tension time of 4 hours without movement of the aircraft is permitted. The adjustment of the cable will not stay correct for a long time. You must do the full pre-tension procedure when the aicraft stops for maintenance for a sufficiently long time.
-For a pre-tension time of between 4 and 48 hours, the stability of the adjustment is in proportion to the pre-tension time.
(a)
Turn the turnbuckles (33) to put a tension of 45 +5 +0 daN (101.1640 +11.2404 +0.0000 lbf) on the cable mechanism. Measure this value with a tensiometer.
(b)
Make sure that you can easily remove and install the pin (2) on the tension regulator (1). If not, adjust the tension again. (Refer to Detail A).
(c)
Install the pin (2) on the input lever of the tension regulator (1).
(d)
You must keep the mechanism in this configuration for 48 hours. Subtask 27-21-61-820-052

(1)
Pressurize the Blue hydraulic system
(Ref. TASK 29-10-00-863-003).
(2)
Turn the turnbuckles (34) to release the tension on the mechanism. Do this until you can remove the locking tool (18) from the tension regulator (1) (Refer to Details L and G).
(3)
Remove the TOOL - LOCKING (FE171901) (18) with the pins (17).
(4)
Make sure that the flanges (23) and (24) are in the correct position related to the cables (21) and (22). Tighten the bolts (28) (Refer to Section JJ).
NOTE : Make sure that you can turn the half shells (25) easily.
____
(5)
Safety the bolts (28) with Lockwire corrosion resistant steel dia 0.8 mm (0.03 in.).
(6)
Turn the turnbuckles until you cannot see the threads of the aft and rear wire rope terminal control cables of the rudder.
(7)
Safety the turnbuckles with the locking clips.
(8)
Make sure that the cables (21) and (22) are aligned correctly on the output of the pulley (42). Tighten the bolts (35) (Refer to Detail M).
(9)
Adjust the control cables length (Ref. TASK 27-21-00-820-002).
NOTE : During the test make sure that:
____ -the deflections of all control components are free,
-there is no interference or friction with adjacent ducts, structures, electrical routing or controls.
NOTE : If you can not adjust the control cables, do a visual
____ inspection on the pulleys and the tension regulator. If they are in good condition, replace the control cables.
(10)
Make sure that the distance between the turnbuckles and the fairleads is minimum 25.4 mm (1.0000 in.) over the full travel range of the rudder control.
(11)
Make sure that the distance between the ends of the turnbuckles in each rudder control cable is minimum 90 mm (3.5433 in.) in all the positions.
