Now
check the
clearance
between
the ratchet
tooth and the
latching

should
be
approximately
equal
for
both
the

in
either
case
.
If
adjustment
is
required
for
either
pawl
the
springs
must
first
be
fully

and
blocked
.
Loosen
seven

and
move
entire
motor
assembly
to
the
rear
if
the
clearance
is under the
minimum
at
the
latching
pawls
,
and
to
the
front
if
the
clearance
is
under
the
minimum
at
the
driving
pawl
.
Move
the
motor
assembly
approximately
twice the
dimensional
in
-
crease
required
at
the
pawl
.
Be
certain
the
motor
assembly
is
moved
straight
forward
or
rearward and
tighten
the
one
bolt
on
the
right
side
of
the
mounting
frame
first
to
assure
proper
alignment
.
After
tightening
the
remaining
bolts
the
springs
should
be released and
the
clearance
again
checked
as
described above
.
striker
(

)
has
traveled
the
maximum
amount
(
about
180
degrees
rotation

cam
)
.
At
this
point
the
clearance
between
the striker and
the switch
support
(

)
should be
1
/
32
"
or
less
.
This
can
be
adjusted
by
loosening
the
switch

position
the clearance
between
the
interlock
switch
arm
(

should
be
1

.
The
driving
pawl
(

must
advance
the ratchet
wheel
(
6
)
sufficiently
on
each
stroke
to
allow the
latching
pawls
(
2
)
to
fall
into
the ratchet
teeth
.
This should
be checked with
the
closing spring
load
against
the
driving
members
.
With
the
mechanism
unblocked
,
hand
charge
the
closing
springs
with the manual
charging
wrench
until
they
are
slightly
more
than
half
charged
.
Slowly
rotate
the
charging
wrench
until
the
driving
pawl
has
traveled
through
its
return
stroke
and
check
the
maximum
clearance
between
the
pawl
and the
ratchet
tooth
.
Rotate
the
charging
wrench
until
the
driving
pawl
has advanced
the
ratchet
tooth
