A. Preparation for a Replacement Component
(1)
Push the piston rod into the body of the servo-control until it touches the internal limit.
(2)
Measure the dimension X. Dimension X must be between 220.0 mm (8.6614 in.) and 223.0 mm (8.7795 in.).
(3)
If the spoiler is safetied with STA-LOK nuts, do the steps that follow:
(a) To adjust the piston rod to get the dimension X: 1 Remove and discard the lockwire from the locknut (70).
_
2 Loosen the locknut (70).
_
3 Turn the eye-end (63) in the applicable direction.
_
4 Make sure that the serrated washers (62) and (69) are engaged
_
correctly.
(4)
When the dimension X is correct, TORQUE the locknut (70) to between
3.0 and 8.0 m.daN (22.12 and 58.99 lbf.ft).
(5)
Safety the locknut (70) with MISCELLANEOUS (Material No. 19-010).
(6)
If the spoiler is safetied with ABS 0738 nuts, do the steps that follow:
(a) To adjust the piston rod to get the dimension X: 1 Remove and discard the lockwire from the locknut (72).
_
2 Loosen the locknut (72).
_
3 Turn the eye-end (63) in the applicable direction.
_
4 Make sure that the serrated washers (62) and (71) are engaged
_
correctly.
(7) When the dimension X is correct, TORQUE the locknut (72) to between
3.0 and 8.0 m.daN (22.12 and 58.99 lbf.ft).
(8) Safety the locknut (72) with MISCELLANEOUS (Material No. 19-010). R **ON A/C 004-049, 053-099, 101-149, 151-199, 201-299, 301-399, 401-499,
