Cycle
Shaft -
Shim
the
cycle
shaft to obtain
.001"
to
.003"
end play
of
the
shaft.
The shims
are
placed
be-
tween
the
left hand
bearing
and
the
check
ratchet.
The
shims
are
available
in various thicknesses
and
are
coded
by
shape as described in
the
Parts
Catalog.
CAUTION:
The
slight
end
play
of
the
shaft insures
that
it
will
rotate
freely.
Excessive
play
could
allow
a coil
of
the
cycle
clutch
spring to wedge between
the
two hub
members
of
the
clutch
causing a machine
lock-up.
(End
play
can
most
easily
be measured with
the
spring clutch
removed.)
NOTE: With
