A. Adjustment of the Hooks
(3) If the value of skin offset S4 is different, do the steps that follow:
(a) Record the delta value of the new measurement (measured between the necessary value and the new value).
(b) Make sure that:
(d) Loosen the bolts (4) and the nuts (6).
(e) Remove the Varnish Polyurethane-- Marking Structure (Material No.04SAB2) from the heads of the bolts (4) and the nuts (6).
(f) Remove the layer of Polysulfide Sealant-General Purpose Interfay - (Material No.06AAC1) from the edge of the hook (1) and the plate (5).
(g) Adjust the locking hook in the Y direction with the delta value of the measurement.
(4) Adjust the hook (1) until it aligns with the notch of the plate (5).
(6) TORQUE the bolts (4) and the nuts (6) to between 1.38 and 1.06 m.daN (122.12 and 93.81 lbf.in )
.
(7) Apply Varnish Polyurethane-- Marking Structure (Material No.04SAB2) to the heads of the bolts (4) and the nuts (6).
