Malselection may be caused by the latch pushers contacting
thei r latch extensions when an unselected pusher is against its
armature. There should be a minimum of .002" clearance
(Fig. 9) between the pusher and the latch extension when the
pusher is against its armature. To check this adjustment, turn
machine power off, trip the cycle clutch, and hand cycle a
few degrees through a cycle. The pusher cam follower should
be on the low dwe
