(b) Install the washers to the detent arm side.
(c) Align the index marks between the torsion rod and the detent
arm.
(d) Adjust the torsion rod axially.
1) BEJ B-2531 THRU B-2532;
Add or remove the washers on the torsion rod until the
detent arm centerline is 1.25 +/- 0.03 inch or 31.75 +/-
0.76 mm (dimension X) from the auxiliary track centerline
(View H-H, Fig. 505).
NOTE: The torsion rod must turn freely after the washer____

add or remove the washers on the torsion rod until the
detent arm centerline is 1.16 +/- 0.03 inch or 29.46 +/-
0.76 mm from the auxiliary track centerline, as initial
measurement before slat installation. Do the final
adjustment of the detent arm after slat installation and
make sure the detent arm is centered on the centerline of
