(5) Manually turn the cam handle until cam axis A's angle is 175°.
(6) Set a dial gauge on station 7's nozzle vertical cam lever and align the
dial gauge to 0. See figure 10-8 for more details.
Note: When the cam angle is 0°, and a dial gauge is set on station 7's nozzle
vertical cam lever, when the cam lever raises, be careful that the tip of the
dial gauge is not damaged. Be sure to set the cam angle to 175°.

(7) While looking at the dial gauge, turn the handle to the left until there
is no change in the dial gauge indicator, when the dial gauge reading
is 0. This point is a point before placement. At this point, cam axes A
and B are synchronized. This also holds true for cam axis B, for
station 7's nozzle vertical cam lever. When the dial gauge indicator is
0, the axes are synchronized. If the axes are synchronized at this
point, the procedure is finished. If they are not continue with
procedures 8 thru 11. See figure 10-9 for more details.

(8) Manually turn the cam handle so that the angle is 175°. Loosen the
span ring bolts on the front head of cam axis B. See figure 10-10 for
more details.

(9) Place a hex wrench on the bolt in the center of cam axis B, and while
watching the dial gauge, turn the handle until station 7's cam nozzle
vertical cam lever stops. While doing this, make sure that cam axis A
does not turn. See figure 10-10 for more details.
(10)Retighten the six span ring bolts. Tighten them in the correct
direction. When retightening the bolts, make sure that there is any
shift in cam axis A or B.
(11)Manually turn the cam axis, when the dial gauge indicator on cam
axis B stops moving, check that the cam angle is 175°. If the cam angle
is not 175° then repeat steps 8 thru 11.
Note: Cam axis A and B should be synchronized to within 2 to 3°.
