(b) If you installed a new cable [9] or cable [11], use the turnbuckles to adjust the tension in the
cables to 125 +10/-0 pounds (56.7 +4.5/-0 kilograms).
(c) Use the turnbuckles [10] to adjust the tension in the cables WFFA and WFFB to the limit
shown in (Table 501).
NOTE: During the adjustment, make sure the tension in the cables is never less than the
minimum. If the temperature is 308 F (08 C) or higher the minimum tension is 50
pounds (23 kilograms). If the temperature is less than 308 F (08 C) the minimum
tension is 30 pounds (14 kilograms).

control valve [19].
(b) If the valve slide [29] does not extend past the index surface [28] in the limit of 0.00 to 0.030
inch (0.00 to 0.76 millimeters), then adjust the trailing edge flap control valve [19]:
1) Loosen the nut [30] and nut [32] on the adjustable sleeve [31].
2) Turn the adjustable sleeve [31] to change the position of the rod end [24] until the valve
