CHASSIS SHEET METAL 11-13
HOOD ADJUSTMENT
The alignment of the hood in relation
to*
other sheet
metal parts is controlled by the position of the hood
hinges and the height of the two bumpers, located one at
each end of the radiator support. The adjustments at
the hood latch must be made after the hinges and bumpers
are positioned to yield the dimensions shown in Figure
17.
Latch adjustments are made so that effort required
to open and close the hood is reasonable, and hood align-
ment obtained by hinge and bumper adjustment is main-
tained when the hood is closed. Note that the hood latch
is not designed or intended to correct basic hood align-
ment faults.
To align the hood and lock, proceed as follows:
HOOD HINGE (Fig. 18)
1.
Note that the mounting holes in the body-mounted
end of the hinge are slotted to provide up and down
movement of the hood assembly while the hood
mounted end is slotted to provide fore and aft move-
ment.
2.
Scribe a mark around the entire hinge plate which
will be involved in the adjustment.
3.
Loosen the appropriate screws and shift the position
of the hood on the hinge plate the approximate amount
to correct misalignment, using the scribed marks to
check amount of movement. Check condition of ad-
justment by tightening cap screws and closing hood.
Fig.

Fig.
19 - Hood Lock, Catch and Support - Chevy II
HOOD BUMPERS
Hood bumpers must be adjusted until hood and fender
line up as shown in Figure 17.
HOOD CATCH AND LOCK (Fig. 19)
Hood lock plate mounting holes are slotted to provide
fore and aft adjustment of the hood lock bolt. The hood
lock bolt itself is adjustable for up and down positioning
of the lock bolt head so that its proper engagement in the
latch assembly may be provided for. The distance that
the lock bolt protrudes out of the lock plate should be
adjusted so that the hood bumpers are slightly com-
pressed by the fully latched hood and so that the effort
required to release the hood catch is reasonable.
FENDER ADJUSTMENT (Figs. 17 and 20)
DO NOT CHANGE SKIRT ASSEMBLY-TO-DASH SHIM-
MING IN AN EFFORT TO ADJUST THE DOOR-TO-
FENDER GAP OR ANY OTHER SHEET METAL AP-
PEARANCE ITEM.
The front fenders are shimmed independently of the
skirt assemblies, unlike conventional- vehicles on which
almost the entire front end sheet metal assembly is
shimmed and adjusted as a unit.
Figure 20 shows the locations of front fender shims.
1.
The rocker panel extension location allows adjust-
ment to make fender outer surface flush with door
outer surface.
2.
The upper or plenum chamber location provides a
means of adjusting fender upper surface so that it
is flush with the upper surface of the cowl.
3.
The locations atop the skirt assembly are shimmed
to close the gap created between the fender mounting
flange and skirt assembly when the plenum chamber

GENERAL DESCRIPTION
The Camaro sheet metal components are much the
same as other Chevrolet passenger models as shown in
Figure 32. The front end design is such that servicing
of the fenders and skirts is most efficiently performed
by removing the fender and skirt as an assembly. Refer
to Section 14 for bumper service procedures, Section 13
for radiator and grille, and Section 1A for air condition-
ing components.
MAINTENANCE AND ADJUSTMENTS
HOOD ADJUSTMENT
The Camaro hood is adjusted in the conventional man-
ner, by adjustment of the hood bumpers and hinges. The
two hood bumpers are located on each side at the top of
the radiator support. Do not attempt hood latch adjust-
ments until the hinges and bumpers are correctly ad-
justed. Latch adjustments are made so that effort re-
quired to open and close the hood is reasonable, and
hood alignment obtained by hinge and bumper adjust-
ment is maintained when the hood is closed. Note that
the hood latch is not designed to correct basic hood mis-
alignment.
HOOD HINGE (Fig. 33)
NOTE: The body mounted portion of the hood
hinges are slotted to provide up and down move-
ment. The hood mounted end is slotted to pro-
vide forward and rearward movement.
1.
Scribe a. line around the entire. hinge plate to be
repositioned.
2.
Loosen the appropriate screws and shift the position
of the hood into correct alignment using the scribe
marks to check amount of movement. Check align-
ment by tightening screws and closing the hood.
HOOD BUMPERS
Adjust hood bumpers so that hood top surface is flush
with fender and header panel top surfaces. See Figure
34 for correct sheet metal adjustment dimensions.
HOOD CATCH AND LOCK (Fig. 35)
Adjust hood lock bolt so that top surface of hood is
flush with top surface'of header panel. The distance that
the lock bolt protrudes out of the lock plate should be
adjusted so that the hood bumpers are slightly com-
pressed by the fully latched hood, and effort required
to release the hood catch is reasonable. Close the hood
and insure catch engages securely.
FENDERS
Fenders are adjustable with shims at the cowl and
rocker panel. To add or remove shims, loosen bolts
Fig. 33 - Hood Hinge - Camaro
at shim locations (fig. 36) and carefully apply force with
pry bar to provide clearance for shim removal or in-
stallation.
SHEET METAL
For proper operation of doors and hood, and for pre-
sentable appearance, adjust front sheet metal to the di-
mensions shown in Figure 34.
COMPONENT PART REPLACEMENT
NOTE: When replacing sheet metal compo-
nents on Camaro, note position and attachment
of all seals and dust shielding and replace if
necessary.

WIPER ASSEMBLY REPAIRS
The overhaul procedures for the wiper are broken down
into three major areas: The motor section, gear box
section and washer pump section. Each section may be
serviced independently of the other.
MOTOR SECTION
Disassembly
1.
Remove the two motor tie bolts.
2.
Remove the armature end-play adjusting screw (fig.
91).
3.
Strike the steel case lightly with a mallet to partiaUy
loosen it from the die casting housing and motor
field.
4.
Insert a tool through the armature adjusting screw
opening and push against the end of the armature
shaft to back off the case. This will retain the ar-
mature commutator in position between the brushes
until ready to separate the armature from the case.
5.
To separate armature from case while still retaining
the brush springs and brushes in place fashion a
spring similar to that shown in Figure 95 and insert
behind the brush leads as shown.
Fig.
95 - Retaining Armature Brushes
6. Pull the armature out of the case and remove the felt
washer, thrust plate, and rubber thrust disc from the
case assembly bearing as required.
7.
The field windings are pressed into the gear housing
and further disassembly is not recommended; how-
ever, the field leads may be unsoldered from the
brush holders to remove the case.
8. Clean and inspect all parts.
Inspect both the field and armature for damage
due to overheating such as unsoldered electrical
connections.
Check that brush leads are firmly attached both
to the brushes and their connections at the brush
holders.
Check brushes for wear. If brushes are worn to
within 3/16" of brush lead, or pigtail, they should be
replaced.
Check contacts of circuit breaker shown at top of
Figure 95. Clean as required or file lightly to re-
move irregularities.
Inspect all leads from the brush and circuit
breaker plate for worn insulation or tjreaks.
If it was determined by inspection that brush re-
placement was required, proceed as follows:
a. Remove retainer installed during disassembly and
remove brush springs.
b.
Place a hot soldering iron against*brush lead con-
nection on brush holders, remove old bushes, and
nection on brush holders, remove old brushes,
and install new brushes.
c. To reinstall brushes in holders, compress spring
within holder and hold fully compressed with a
thin instrument inserted through the slot in the
brush holder. Then push brush into holder with
lead upward to project through slot in holder, hold
