the
gauge
between
flyweights
and
against

gauge
with
a .003
inch
feeler.
If

heel
is tight
on
feeler,
replace
the
cam

contact
areas.
(Refer
to Figure

If either
ear
shows
a perceptible
groove
or a ridge
can
be
felt when
fingernail
is drawn
across
the
surface,
replace
the
coupling
body.
g.
Inspect
drive
lugs
of
body.
If wear
is noted,
measure
difference
between
worn
and
unworn
areas
on
drive lug
surface.
If
difference
is in excess
of
.015
of an
inch,
replace
the
body.
