(a) If they are in good condition:
1 Make a mark on each rear cable.
_
2 Pull the cables to the front until the position of the index
_ agrees with the value found on the graph.
3 Keep the cables pulled and make a new mark on each cable then
_
release the cables.
4 Measure the length between two marks of each cable
_ R - if the length is more than 32 mm (1.2598 in.), shorten the
control cables (Ref. TASK 27-41-00-820-003). R - if the length is less than 32 mm (1.2598 in.), replace the R rear control cables (Ref. TASK 27-41-44-000-001) (Ref. TASK
27-41-44-400-001).

Remove the PIN - RIGGING (0U190360) (5).
(8)
Energize the aircraft electrical circuit (Ref. TASK 24-41-00-861-002).
(9)
Pressurize the Green and Yellow hydraulic systems (Ref. TASK 29-23-00-863-001) and (Ref. TASK 29-24-00-863-001).
(10)
Operate the THS fully more than ten times and put it in the zero position.
(11)
Install the PIN - RIGGING (0U190360) (5).
(12)
Depressurize the Green and Yellow hydraulic systems (Ref. TASK 29-23-00-864-001) and (Ref. TASK 29-24-00-864-001).
(13)
De-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002).
(14)
Make sure that the position of the index (4) agrees with the values found on the graph with a tolerance of + or - 1 graduation (+ or -5.C).
(15)
Make sure that the pitch-trim control-wheels stay at zero.
(16)
With a tensiometer, measure the tension of the two cables at a distance no less than 200 mm (7.8740 in.) from the tension regulator (2). Do this step two times to make sure that you get the same tension value.
(17)
Make sure that the tension value is 20 +8 -4 daN (45 +18 -9 lbf).
