R  B. Installation of the Shroud Box 
R  (1) Carefully lift the shroud box into the correct position in the wing. 
R  Align all the attachment brackets with the related attachment 
R  brackets on the: 
R  - overwing panel 
R  - fixed shroud 
R  - fuselage. 
R  NOTE : The correct position of the shroud box on the aircraft is____ 
R  controlled by the attachment points as follows: 
R  - the position of the outboard end is controlled by the 
R  attachment brackets on the fixed shroud 
R  - the forward and aft position is controlled by the bolt holes 
R  in the overwing panel 
R  - the up/down position is controlled by the rods on the 
R  inboard end between the shroud box and the brackets on the 
R  fuselage. These rods are set and locked at aircraft build 
R  and must not be adjusted. 
R  (2) Support the shroud box. 
R  (3) At the outboard aft attachment bracket: 
R  (a) Align the hole in the outboard aft attachment bracket (91) (on 
R  the shroud box) with the hole in the bracket on the fixed shroud. 
R  (b) Install the floating bushes (90) into the outboard aft attachment 
R  bracket (91). 
R  (c) Install the bolt (92), the washer (93), the washer (89) and the 
R  nut (88).

R (d) Do not fully tighten the nut (88) at this stage.

R  (4) At the outboard forward attachment bracket: 
R  (a) Align the slotted hole in the outboard forward attachment bracket 
R  (78) (on the shroud box) with the hole in the bracket on the 
R  fixed shroud. 
R  (b) Install the slider bushes (77) into the outboard forward 
R  attachment bracket (78). 
R  (c) Install the bolt (75), the washer (76), the washer (81) and the 
R  nut (79). 
R  (d) Do not fully tighten the nut (79) at this stage. 
R  (5) At the inboard aft attachment bracket: 
R  (a) Align the hole in the end of the rod (56) with the hole in the 
R  inboard aft attachment bracket (61). Do not adjust the length of 
R  the rod (56). The rod (56) is set and locked at aircraft build 
R  and must not be adjusted. 
R  (b) Install the floating bush (57) into the inboard aft attachment 
R  bracket (61). 
R  (c) Apply a thin layer of COMMON GREASE (Material No. 04-004) to the 
R  bolt (53). 
R  (d) Install the bolt (53), the washer (54), the washer(s) (58) and 
R  the nut (60). 
R  (e) Do not fully tighten the nut (60) at this stage. 
R  (6) At the inboard center attachment bracket: 
R  (a) Align the hole in the rod (47) with the hole in the inboard 
R  center attachment bracket (42). Do not adjust the length of the 
R  rod (47). The rod (47) is set and locked at aircraft build and
