GENERAL DESCRIPTION

The new front end appearance of the 1967 Chevrolet

and Chevelle passenger cars affects the servicing and

replacement of the chassis sheet metal. Refer to Section

13 for Radiator and Grille service procedures, Section
14 for Bumpers, and Section 1A for Air Conditioning

components. Figures 1 and 2 illustrate the Chevrolet

and Chevelle sheet metal components.

MAINTENANCE AND ADJUSTMENTS

HOOD ADJUSTMENT

The alignment of the hood is controlled by the position

of the hood hinges and the height of the two bumpers lo-

cated one at each side of the radiator support. The ad-

justment at the hood lock must be made after the hinges

and bumpers are properly adjusted. To align the hood

and lock proceed as follows:

HOOD HINGE (Fig. 3)

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 re-

positioned.
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 the fender and grille top surfaces. Refer to Fig-

ures 4 and 5 for correct sheet metal adjustment dimen-

sions.

HOOD CATCH AND LOCK

The hood catch assembly (fig. 6) mounting holes are

slotted to provide adjustment for the hood lock bolt. Ad-

just the hood lock bolt until hood engages securely when

closed and hood bumpers are slightly compressed.

CHEVROLET CHASSIS SERVICE MANUAL

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.

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

Service Operation . 15-15

GENERAL DESCRIPTION

A pneumatic level control system that automatically

maintains correct rear trim height of a car under varying

load conditions, the optional automatic level control is

used only in conjunction with the Superlift Shock Absorber

option.

The Superlift Shock Absorber option alone, consists of

the two shock absorbers with pressure lines to a "Tee"

where a ill valve is located, the shocks are inflated

with (or deflated of) compressed air (at any gas station)

to obtain the vehicle level desired with any given load

change.

The automatic leveling system is added to the Superlift

Shock Absorbers and supplies its own compressed air.

The system (fig. 13) consists of a vacuum operated air

compressor with pressure regulator,
and
integral storage

tank, vacuum line to engine, air intake filter, air lines,

and a height control valve.

The COMPRESSOR is a two-stage, vacuum actuated

type, requiring no lubrication. Vacuum supply is taken

from engine carburetor base. High pressure air is
supplied to the reservoir tank by the second stage of

the two-stage compressor. The first stage intake stroke

draws air at atmospheric pressure through a oneway

check valve located in the end of the first stage housing

under the first ^tagei housing cover. On the first stage

compression stroke, the intake valve is closed and the

oneway check valve in the second stage end of the piston

is opened. This allows the air from the first stage

cylinder to flow through the hollow piston into the second

stage cylinder for jhigh pressure compression. The

second stage compression stroke closes the check valve

in the piston and opeijis the check valve in the end of the

second stage housing.

The intake and compression strokes are controlled by a

sliding distributor valive that is actuated through an arm

that is tripped by the piston as it nears the end of each

stroke. Each time the arm actuates the distributor

valve, a different set of holes are covered in the first

stage housing. The distributor valve controls the flow of

intake manifold vacuum and air under atmospheric pres-

available pressure.

NOTE: If available pressure is less than 140

psi,
start engine to build-up reservoir to this

pressure.

Regulated pressure should build-up to and hold

steady at 100-130 psi on test gauge.

Check regulated pressure by momentarily (not more

than one second) depressing valve core on test gauge

arid observe gauge reading.

If regulated pressure now reads less than 100 psi,

replace regulator assembly.

If regulated pressure exceeds 130 psi, replace regu-

lator assembly.

4.
If Superlifts inflate and then leak down, perform leak

test on lines and fittings and then on Superlifts and

control valve. Repair or replace as indicated.

Time Delay Test (Reservoir Pressure 125 psi Minimum)

1.
Record rear trim height of empty car (rear bumper

to ground).

2.
Add weight equivalent to two passenger load to rear

of car. Car should begin to level in 4-18 seconds.

3.
Remove weight. After 4-18 seconds car should begin

to settle.

4.
Replace valve if time delay is not within the 4-18

seconds.

Trim Adjustment—On Car

Trim adjustment should be performed with a full fuel

tank (or the equivalent in load at the rate of 6 lbs
./gal-

lon)
,
but no other load.

Abbreviated Adjustment

1.
Fill the compressor at the service valve with the

available air line pressure.

2.
Disconnect link from height control valve lever.

Move the height control valve lever upward until air

fills the Superlifts.

3.
Move lever downward and hold until air stops escap-

ing from the exhaust port of the height control valve.

The Superlifts will now automatically hold 8 to 15

PSI.
;

4.
Let lever go to its neutral position> and loosen the

lever adjustment nut.

5.
Assemble the link to the height control valve lever

and tighten the lever adjustment nut.

NOTE: Do not move control valve lever and

overtravel body while tightening nut.

Leak Tests

Compressor, Reservoir and Regulator

1.
Remove assembly intact.

2.
