(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°.

Alternately, use a tension meter to adjust the tension to a suitable
frequency .
