R (4) Remove the nut (49) and the washer (48). Remove the bolt (47)
R sufficiently so that you can install the correct quantity of shims
R (51).
R (5) Install the shims (51) then fully install the bolt (47), the washer
R (48) and the nut (49).
R (6) TORQUE the nut (49) to between 1.7 and 1.8 m.daN (12.53 and 13.27
R lbf.ft).
R (7) Examine the related positions of the hole in the bolt (47) and the
R slot in the nut (49).
R (8) TORQUE the nut (49), until the next slot aligns with the hole, to 2.8
R m.daN (20.64 lbf.ft) maximum.
R (9) Safety the nut (49) with a new cotter pin (50).
R (10) Move the fairing (up and down) to make sure that the sidestay (46) is
R free to turn.
R (11) Apply a thin layer of SEALANTS (Material No. 09-018) or SEALANTS
R (Material No. 09-019) to the interfaces of the bush (42) and the bolt
R (41), but not to the threads.
R (12) Align the control rod (45) with the flap drive arm and install the
R bolt (41), the bush (42) and the nut (43).
R (13) Safety the nut (43) with a new cotter pin (44).
R (14) Measure the dimension 'B', this must be 11 mm (0.4330 in.).
R (15) Temporarily install the top cover (10) with some of the screws (11).
R (16) Measure the dimension 'G', this must between 3 mm (0.12 in.) and 1 mm
R (0.04 in.).
R (17) If you installed a new movable fairing and the dimension(s) 'G' is
R not correct, do the steps that follow:
R (a) Remove the screws (11) and the top cover (10).
R (b) Remove the nut (22) the bolt (21) and disconnect the lower
R bonding strip (20) from the rod P-clip.
R (c) If necessary, remove and discard the lockwire from the locknuts
R on the rod (45).
R (d) Loosen the locknuts sufficiently to let you turn the rod body.
R (e) Turn the rod body clockwise or counterclockwise to adjust the rod
R length.
R (f) Temporarily install the top cover (10) with some of the screws
R (11).
R (g) Measure the dimension 'G' again.
R (h) Remove the screws (11) and the top cover (10).
R (i) Safety the locknuts on the rod assembly to the tabwashers with
R MISCELLANEOUS (Material No. 19-010).
R (j) Install the bonding strip (24) on the P-clip with the bolt (23)
R and the nut (25) (Ref. TASK 20-28-00-912-004).
R (k) Install the bonding strip (20) on the P-clip with the bolt (21)
R and the nut (22) (Ref. TASK 20-28-00-912-004).
