Use the TOOL FLAP ADJUSTING to adjust the main eccentric bearings. Adjust the bearings at one track position then the other in small increments. Set the inboard flap as follows:
(a) At the track 1 and the track 2 positions, adjust the main eccentric bearings until:
(3)
At the track 1 position:
(a)
Measure the dimension Q (between the flap drive-arm (4) and the rotary actuator drive-lever (5)).
(b)
If the dimension Q is less than 2 mm (0.0787 in.), a force of not more than 25 kg (55.1155 lb) can be applied to the fork of the flap drive-arm (4) to align the holes.
(c)
Loosely install the bolt (6).
(d)
If the dimension Q is more than 2 mm (0.0787 in.), then adjust the forward eccentric (in the flap drive-arm) until the dimension Q is not more than 2 mm (0.0787 in.). To do this:
1_ At track 2, the top surface of the flap aligns +/- 1.0 mm
(0.0393 in.) with the zero line on the scale block (68).
NOTE : Look inboard from the outside of the flap track beam____
when you read the scale block.
2_ The dimension S (between the bottom surface of the shroud box
trailing-edge and the top surface of the flap at the WX500
position) is between 4.5 mm (0.1771 in.) and 8.0 mm (0.3149
in.).
(Ref. Fig. 526/TASK 27-51-00-991-076)
1 Remove and discard the cotter pin (92).
_
2 Remove the nut (95), the washer (94) and the serrated
_ lockwasher (96).
3 Loosen the nut (91) sufficiently to let the eccentric bolt
_
(97) move. 4 Turn the eccentric bolt (97) until the dimension Q is not more
_ than 2 mm (0.0787 in.) and loosely install the bolt (6).

(4)
Remove the TOOL RESTRAINING TK1 from the flap track 1 beam (Ref. Para 4.K.(2)).
(5)
Do a check of the flap rigged position again to make sure that it is in the specified limits. If the flap rigged position is not correct:
(a)
Install the TOOL RESTRAINING TK1 (98D27504039000) on the flap track 1 beam (Ref. Para 4.F.(2)).
(b)
Disconnect the track 1 flap drive levers (4) and (5).
(c)
Put the track 1 main eccentric bearing back to its zero datum position.
(d)
Do steps (2) thru (6) again until the flap is in the correct rigged position.
(e)
Tighten the nut (91) and install a new cotter pin (92).
(f)
Install the serrated lockwasher (96) with the end of the bolt
(93)
through its hole.
(6)
Apply a layer of SPECIAL MATERIALS (Material No. 05-002) to the threads of the bolt (93).
(7)
Install the washer (94) and the nut (95).
(8)
Apply a layer of STORAGE PRESERVATION (Material No. 15-007) to:
-the cotter pin (92), the nuts (91) and (95), the washer (94) and the eccentric bolt (97).

(1) At the track 1 position:
(a)
Remove the TOOL-FLAP ADJUSTING from the eccentric bush (86).
(b)
Install the toothplate (85), the lockwasher (84) and the nut (83).

(c)
TORQUE the nut (83) using the TORQUE ADAPTOR-TRUNNION NUT (98D27504035000) to between 5.4 and 7.0 m.daN (39.82 and 51.62 lbf.ft).
