CAUTION: NEVER EXTEND THE TAPPET MORE THAN
1.75 in. (44.5 mm). See Figure 29. Over-extending the
tappet will result in the tappet losing engagement with
the synchronizing mechanism. Since the mechanism
can only be set at the manufacturing plant, the caliper/
carrier assembly must be replaced if this happens.
