ADJUSTMENTS

POWER STEERING GEAR

Chevrolet, Chevelle, and Camaro

The over-center adjustment (fig. 64) is the only power

steering gear adjustment which can be made on the car.

However, in order to make this adjustment, it is also

necessary to check the combined ball and thrust bearing

preload.

If the vehicle is equipped with a tilt column it will be

necessary to disconnect the steering coupling to obtain a

torque reading of the column. This torque should then be

subtracted from any reading taken on the gear.

1.
Disconnect the pitman arm from the relay rod.

2.
Loosen the pitman shaft adjusting screw loeknut and

thread the adjusting screw out to the limit of its

travel through the side cover. '. •

3.
Disconnect steering column harness at chassis wir-

ing connector plug.

4.
Remove horn button.

5.
Turn the steering wheel through its full travel, then

locate the wheel at its center of travel.

6. Gheck the combined ball and thrust bearing preload

with an inch-pound torque wrench on the steering

shaft nut by rotating through the center of travel

(approximately 1/4 turn in each direction). Note the

highest reading.

7.
Tighten the pitman shaft adjusting screw and check

torque at steering shaft nut until over center preload

and total steering gear preload falls within speci-

fications. Refer to torque specifications at rear of

manual for correct torque values.

8. Install horn button. Connect steering column harness

at wiring connector plug.

The steering gear used with power steering is adjusted

in the same manner as the manual steering gear.

PUMP BELT TENSION

1.
Loosen nut on pivot bolt and pump brace adjusting

nut.

CAUTION: Do not move pump by prying against

reservoir or by pulling on filler neck.

2.
Move pump, with belt in place until belt is tensioned

to specifications as indicated by Tool J-7316 (Fig-.

65).

3.
Tighten pump brace adjusting nut. Then tighten pivot

bolt nut.

HYDRAULIC SYSTEM CHECKS

The following procedure outlines methods to identify

and isolate power steering hydraulic circuit difficulties.

This test is divided into two parts. Test number one

provides means of determining whether power steering

system hydraulic parts are actually faulty. If test number

one results in readings indicating faulty hydraulic opera-

tion, test number two will identify the faulty part. Be-

fore performing hydraulic circuit test, carefully check

belt tension and condition of driving pulley. Strand

tension of belt should be 125 lbs. on new belts and 75 lbs.

on old belts, as indicated by Tool J-7316 (Fig. 65).

Test Number One—Oil Circuit Open

Engine must be at normal operating temperature. In-

flate front, tires to correct pressure. All tests are made

with engine idling, so adjust engine idle speed to correct

specifications listed in Section 6 and proceed as follows:

a. With engine not running, disconnect flexible pres-

sure line from pump and install Tool J-5176 as

Figure 71. On Chevelle models with 396 engine, install

the upper hose so that there is at least .6 inch clearance

between the hose and the Delcotron or the inner fender

skirt.

It is important that the power steering hoses be in-

stalled correctly. Hoses installed out of position may be

subjected to chafing or other abuses during sharp turns.

Always make hose installations with front wheels in

straight ahead position. Do not twist hoses unneces-

sarily during installation.

CAUTION: Do not start engine with any power

steering hose disconnected.

CHEVROLET CHASSIS SERVICE MANUAL

CHASSIS SHEET METAL 11-20

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.

FJg.
1 - Fuse Panel Assembly

All power window and tailgate circuits require the igni-

tion switch to be "ON" to open or close the windows un-

like past model designs which were operated independ-

ently of the ignition switch.

The windshield wiper and washer switch is new in that

washer button in the center of the knob has been deleted
and its function will be accomplished by pushing the knob.

A set screw is used to retain the knob to the shaft.

In addition to fuses, the wiring harness incorporates

fusible links to protect the wiring. Links are used rather

than a fuse in wiring circuits that are not normally fused,

such as the ignition circuit. Fusible links in the Chevro-

let wiring are four gauge sizes smaller than the cable it

is designed to protect. The links are marked on the

insulation with wire gauge size because of the heavy insu-

lation which makes the link appear a heavier gauge than it

actually is.

Engine compartment wiring harness incorporate sev-

eral fusible links. Each link is identified with its gauge

size.
A fusible link is a length of special wire (normally

four wire gauges smaller than the circuit it is protecting)

used in wiring circuits that are not normally fused, such

as the ignition circuit. The same size wire with a spe-

cial hypalon insulation must be used when replacing a

fusible link.

The links are:

1.
The pigtail lead at the battery positive cable (except

Corvette) is a 14 gauge, brown fusible link protecting

the 10 gange battery charging circuit. This wire is

an integral part of the battery cable assembly and

servicing requires replacing the complete battery

cable assembly. On Corvette models this link is

installed as a molded splice at the solenoid "Bat"

terminal and servicing requires splicing in a new

link.

2.
A 16 gauge black fusible link is located at horn relay

to protect all unfused wiring of 12 gauge or larger.

It is a serviceable piece with an in-line connector

and is not integral with the wiring harness.

3.
The generator warning light and field circuitry (16

gauge wire) is protected by a fusible link (20 gauge

orange wire) used in the "battery feed to voltage

regulator #3 terminal" wire. The link is installed

as a molded splice in the generator and forward lamp

harness and is serviced by splicing in a new 20 gauge

wire as required.

4.
The ammeter circuit on all models is protected by

two orange, 20 gauge wire fusible links installed as

molded splices in the circuit at the junction block or

the solenoid "Bat" terminal (Corvette only) and at the

horn relay. Each link is serviced by splicing in a

new 20 gauge wire as required.

The wiring harnesses use a standarized. color code

common to all Chevrolet vehicles. Under the color code,

the color of the wire designates a particular circuit. The

harness title indicates the type of harness, single of mul-

tiple wire, and also describe the location of the harness.

The body harness is a flat, solid wire assembly and is

routed through the vehicle near the center of the body.

Composite wiring diagrams (figs. 104 thru 124) are in-

cluded at the end of this section.

MAINTENANCE AND ADJUSTMENTS

Maintenance of the lighting units and wiring system

consists of an occasional check to see that all wiring

connections are tight and clean, that the lighting units are

tightly mounted to provide good ground and that the head-

lamps are properly adjusted. Loose or corroded con-

nections may cause a discharged battery, difficult start-

ing, dim lights, and possible damage to generator and

regulator. Wire harnesses must be replaced if insulation

becomes burned, cracked, or deteriorated. Whenever it
is necessary to splice a wire or repair one that is bro-

ken, always use solder to bond the splice. Always use

rosin flux solder on electrical connections. Use insulat-

ing tape to cover all splices or bare wires.

When replacing wires, it is important that the correct

size be used. Never replace a wire with one of a smaller

size.

Each harness and wire must be held securely in place

by clips or other holding devices to prevent chafing or

WINDSHIELD
WASHER PUMP

The windshield washer pump used on the 2-speed Type

"E"
wiper motor assembly is a positive displacement

type pump employing a small bellows, bellows spring and

valve arrangement. The pumping mechanism is actuated

by a four lobe cam and driven directly by the wiper motor

(fig. 71). Thus, when the wiper is operated, this rotor is

always turning with the gear. Programming is accom-

plished electrically and mechanically by a relay assembly

and ratchet wheel arrangement.
