NOTE : Label (42) shows the shark-fin calibration value at track 4.
____ Aircraft with this label used to have the outer fixed shroud as the datum point. The shark-fin uses the flap track beam as a datum. The shark-fin calibration value is the difference (distance) between the fixed shroud datum and the flap track beam datum. The value must be included when the position of the flap trailing edge is set.
(1) Use the TOOL FLAP ADJUSTING to adjust the main eccentric bearings. Adjust the bearings at one track position then the other in small, equal increments. At the track 3 and the track 4 positions, adjust the main eccentric bearings until:
(a) At the track 3 position, the flap top surface aligns:
-with the zero line on the scale block (20), plus or minus 1.0 mm (0.0393 in.).
NOTE : Look inboard from the outside of the flap track beam when
____
you read the scale block.
(b) At the track 4 position, the flap top surface aligns:
-with the line on the scale block (20) which agrees with the calibration value on the track 4 label (42).
NOTE : Look inboard from the outside of the flap track beam when
____
you read the scale block.
