 (1) Adjust the two turnbuckles to the dimension 'C' = 30 mm (1.18 in.).
 (2) Find the correct value to cut the cables.
 NOTE : Cut the two rear cables by the same value.____
 (a) Use the adjustment graph to find the position of the index of the tension regulator (1) in relation to the ambient temperature.
 (b) Put marks on the two cables where the cable routing is straight and near the structure.
 (c) In the fuselage between two static fairleads, pull the two cables at the same time until the index of the tension regulator is at the position found on the graph.
 NOTE : Pull the cables down to get the necessary force, and____ measure the cable travel 'Y' along the aircraft axis.
 (d) Measure with the marks (on the cables and on the structure) the cable travel 'Y' on each cable to get the necessary cable length. 
R R  (e) For each cable side, subtract 45 mm (1.7716 in.) from the value measured before. 
R R R  NOTE : 45 mm (1.7716 in.) is the cable penetration into the____ terminal stud of one turnbuckle. 
R R  (f) The value 'X' (to cut the cable) = 'Y' (cable travel) - 45 mm (1.7716 in.).

 

R R R  Example: Measured cable travel 'Y' for each cable Cable penetration into the terminal stud Value 'X' to cut the cable  = 110 mm (4.33 in.) = 45 mm (1.77 in.) = 110 mm - 45 mm = 65 mm (4.33 in. - 1.77 in. = 2.55 in.) 
R  Cut the two rear cables by 65 mm (2.55 in.)
 (3) Use the measured clearance between the turnbuckles and the static fairleads to cut the rear cable junction by the calculated value.
 NOTE : Cut the two rear cables by the same value.____
 (4) Install the new turnbuckles on the cable (Ref. CFM Cable Fabrication Man).
 (5) Do the adjustment of the rudder control-cables length (Ref. TASK 27-21-00-820-002).
 (6) Make sure that the clearances 'A' between the two turnbuckles and the fairleads is minimum 25.4 mm (1.00 in.) along the full travel range of the rudder control.
 (7) Make sure that the distance 'B' between the ends of the turnbuckles in each rudder control cable is minimum 90 mm (3.54 in.) in all the positions.
 (8) Make sure that the turnbuckles are in the adjustment range of 38.2 mm (1.50 in.).
