F Access Doors 195BB and 196BB - Clearances
NOTE: This adjustment procedure is given for one access door. The procedure for the other access door is the same.
   (1) Measure clearances J1 and J3 between the access door (3) and the door (31).
   (2) Make sure that clearances J1 are 3.0 -1.0 mm or +1.0 mm (0.12 -0.04 in. or +0.04 in.).
   (3) Make sure that clearances J3 are 3 -2.0 mm or +2.0 mm (0.12 -0.08 in. or +0.08 in.).
   (4) If a minimum of one clearance J1 or J3 is out of the tolerances, adjust the access door (3) as follows:
     (a) Loosen the nuts (8) and move the hinges (6) as necessary.
     (b) Tighten the nuts (8).
   (5) Measure skin offsets J2 and J4 between the access door (3) and the door (31).
   (6) Make sure that skin offsets J2 are 0.0 -1.0 mm or +1.0 mm (0 -0.04 in. or +0.04 in.).
   (7) Make sure that skin offsets J4 are 0.0 -1.5 mm or +1.5 mm (0 -0.06 in. or +0.06 in.).
   (8) If a minimum of one skin offset J2 or J4 is out of the tolerances, adjust the access door (3) as follows:
     (a) Remove the nuts (8), the screws (5) and (12), the washers (4) and (7) and the hinges (6).
     (b) If necessary, prepare again the surface of the bonding point(s) at the screw (12) (Ref. AMM TASK 20-28-00-912-803).
     (c) If necessary, apply Paste Adhesive-- Liquid shim - (Material No.13FGC1) on the mating surfaces of the hinges (6).
