DOORS
ADJUSTMENTS
Door Lock Striker
Door lock strikers incorporate
an
inter-lock feature
consisting
of a
notch
in the
striker into which the lock
bolt housing extension engages. With
the
inter-lock
feature
it is
very important that
the
lock extension en-
gages properly
in the
striker notch
and
that, where
necessary,
the
correct striker emergency spacers
are
used to obtain proper engagement.
1.
To
adjust striker
up,
down,
in, or
out loosen striker
plate screws and shift striker and adjusting plates
as
required, then tighten screws.
2.
To determine
if
door lock striker emergency spacers
are required, apply modeling clay
or
body caulking
compound
in the
door lock striker notch where
the
lock extension engages,
and
then close
the
door
to
form
a
measurable impression in the clay
or
caulk-
ing compound,
as
shown
in
Figure
24.
Remove
all
clay
or
compound when adjustment
is
completed.
When dimension
"A"
from inside face
of
striker teeth
to center
of
lock extension
is
less than 3/16", install
emergency spacers
and
proper length striker attaching
screws.
NOTE:
Dimension
"B"
from center
of
lock
extension
to
inside face
of
striker notch should
.
never be less than 1/8".
If check indicates need
for
emergency spacers,
pro-
ceed
as
follows:
1.
With pencil, scribe position
of
striker on body pillar.
2.
Remove three door lock striker attaching screws and
remove striker
and
adjusting plates from pillar.
3.
To
install, place striker, shims and adjusting plates
within scribe marks
on
pillar
and
tighten screws.
IMPORTANT: Whenever
a
door
has
been
re-
moved
and
installed,
or
realigned,
the
door
SHOULD NOT be closed completely until
a
visual
check
is
made to determine
if
the lock extension/
will engage
in the
striker notch. Where
re-
quired, door lock striker emergency spacers
should
be
installed
so
that door
can be
closed
and
an
accurate check made to determine emer-
gency spacer requirements.
Door Window and Vent Adjustment
To move
the top of the
window
in or
out, the bottom
ends
of
both
run
channels
are
adjustable.
The
rear
channel
is
adjusted
by
loosening
the
lower
of
the two
screws
on the
rear face
of
door, "C" Figure 25, and
moving channel
as
necessary.
The
front channel
is ad-
justed
by
removing
the
trim pad and moving the Channel
in
or out by a
stud
and nut
adjustment, "B" Figure 25.
The
top end of the
rear channel
is
not adjustable in
or
out.
On 19467 models
an
adjustment
may be
made
to the
closed-door relationship
of the
vent assembly
to the
windshield frame. This adjustment
is
controlled
by the
stud-nut assembly "B" Figure
25.
The closed position
of the
window
is
controlled
by
bumper assemblies located
at
each end
of
window frame
as shown
in
Figure
26.

refer to Section 6 of the Chassis Overhaul Manual.
Because of the interchangeability and similarity of
many engines, engine sub-assemblies and engine parts,
regardless of which passenger vehicle they are used in,
typical illustrations and procedures are used except
where specific illustrations or procedures are necessary
to clarify the operation. Although illustrations showing
bench operations are used, most single operations, when
not part of a general overhaul, should be performed (if
practical) with the engine in the vehicle.

each capacitor (not illustrated). The capacitor is
shorted if both readings are zero.
6. Resistor Rl: The resistor is open if both readings
are infinite.
7. Resistor R2: Use an ohmmeter scale on which the
1800 ohm value is within, or nearly within, the
middle third of the scale. If both readings are infi-
nite, the resistor is open.
8. Resistor R3: Use an ohmmeter scale on which the
680 Ohm value is within, or nearly within, the middle
third of the scale. If both readings are infinite, the
resistor is open.
9. Resistor R4: Select an ohmmeter scale on which the
15000 ohm value is within, or nearly .within, the
middle third of the scale. If either reading is infi-
nite, the resistor is open. ~
10.
Resistor R5: Use the lowest range ohmmeter scale.

NOTE:
This resistor on some applications may
be located in the vehicle wiring harness, and not
on the panel board.

REASSEMBLY
During assembly, coat with silicone grease both sides
of the flat insulators used between the transistors and
heat sink, and also the heat sink on the side on which the
transistors are mounted. The silicone grease, which is
available commercially, conducts heat and thereby pro-
vides better cooling.'

HOOD ASSEMBLY (Fig. 10)
Hood may be removed either with or without hinges.
To shorten aligning time, scribe a mark on hood around
the hinge plate. See adjustment procedures in this sec-
tion for hood adjustment. Hood hinge springs may be
easily and safely removed and installed using Tool J-9559
as follows:
1.
Remove bolt from Tool J-9559.. Open hood far
enough to allow passage of tool between hood and
fender and insert encls of tool between coils of spring
until barrel of tool contacts outer diameter of spring.
2.
Open hood full while holding spring (with tool in-
stalled) in hand; when hood is in opened position,
remove spring as shown in Figure 11. .
3.
When spring is removed, insert long bolt supplied
with J-9559 through holes in ends of tool, passing it
through spring, and install nut on bolt.
Spring may be removed from J-9559, or J-9559 may
be installed in a new spring by the following method:
1.
Place a closed 6. or 8. inch "CTt clamp in a vise or
fasten it to a' heavy bench top (bench should be fas-
tened to floor).
2.
Hook one end of spring in clamp and the other end
in hook of hoist as shown in Figure 12.
3.
Stretch the spring enough to allow insertion of
J-9559. Install bolt if spring is not to be installed
on hinge at once.
