C. Installation of the Wing-Tip Brake
   (1) Put the wing-tip brake (1) in position on the outboard face of the rib. Make sure that the locating stud is in the correct position.
   (2) Make sure that:

• The torque shaft splines engage correctly in the wing-tip brake (1).
  
• You cannot see the spline engagement groove.
  

   (3) Hold the wing-tip brake (1) and install the nuts (17).
   (4) TORQUE the nuts (17) to between 0.55 and 0.5 m.daN (48.67 and 44.25 lbf.in ) .
   (5) Apply Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) or Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) over the nuts (17) and the locating stud and to the mating face of the brake.
   (6) Adjust the relative position of the brake support (19) and the wing-tip brake (1) with the washers (25) as necessary:
     (a) Install a minimum of 1 and a maximum of 3 washers (25) on each stud.
     (b) Install the remaining washers (25) between the brake support (19) and the nut (23).
   (7) Install the brake support (19), the washers (24) and the nuts (23).
   (8) TORQUE the nuts (23) to between 0.55 and 0.5 m.daN (48.67 and 44.25 lbf.in ) .
   (9) Apply Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) or Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) to the shank of the bolt (18), the nuts (23) and the washers (24).
   (10) Install the bolt (18), the washer (20) and the nut (21).
   (11) TORQUE the nut (21) to between 0.8 and 0.7 m.daN (70.80 and 61.95 lbf.in ) .
   (12) Safety the nut (21) with the AIPC 27-54-05-25-240 COTTER PIN (22) or AIPC 27-54-85-20-410 COTTER PIN (22).

CAUTION: DO NOT APPLY MORE THAN ONE TYPE OF LUBRICANT. GREASE AND ASSEMBLY PASTE DO NOT MIX.

   (13) Apply a layer of Corrosion Preventive Compound-Heavy Duty Soft Film - (Material No.12ACC1) to:

• The bolt (18) and the washer (20)
  
• The nut (21) and the cotter pin (22)

   (14) Do one of the steps that follow:
     (a) Apply a thin layer of Synthetic Oil base Grease-General Purpose Clay Thickened - (Material No.03GBB1) or Synthetic Oil base Grease-General Purpose Lithium Thickened Low Temp. - (Material No.03GBC1) or Mineral Oil base Grease-Anti-Fretting Paste - (Material No.03FDB1) to the splines of the universal joint (28).
   (15) Install the universal joint (28) in the wing-tip brake (1) in a position where the flange bolt holes are aligned.
   (16) If the middle part of the torque shaft was removed, install it (Ref. AMM TASK 27-54-45-400-008) and (Ref. AMM TASK 27-54-45-400-011).
   (17) Install the bolts (26) and the nuts (27).
