1967 CHEVROLET CAMARO load capacity

LUBRICATION 0-16

Every 12,000 miles (more frequently*, depending on

severity of service, if vehicle is used to pull trailers,

carry full loads during high ambient temperatures,

operate in mountainous terrain or operate under other

severe conditions--Remove fluid from the transmission

sump and add one and a half quarts of fresh fluid for

Camaro and Chevy II and two quarts for Chevrolet,

Chevelle, and Corvette. Operate transmission through all

ranges and check fluid level as described above.

•Except if vehicle is equipped with transmission pro-

vided in heavy duty service options. If so equipped,

drain converter and pump every 12,000 miles and add

approximately seven and a half quarts of fresh fluid

for Chevy II and nine quarts for Chevrolet and Chevelle.

TURBO HYDRA-MATIC

Lubrication. recommendations for the Turbo Hydra-

Matic are the same as outlined for the Powerglide

transmission except for fluid capacity and filter change

listed below.

After checking transmission fluid level it is important

that the dip stick be pushed all the way into the fill tube.

Every 12,000 miles — after removing fluid from the

transmission sump, approximately 7 1/2 pints of fresh

fluid will be required to return level to proper mark on

the dip stick.

Every 24,000 miles, or at every other fluid change--

the transmission sump strainer should be replaced.

FRONT WHEEL BEARINGS

It is necessary to remove the wheel and hub assembly

to lubricate the bearings. The bearing assemblies should

be cleaned before repacking with lubricant. Do not pack

the hub between the inner and outer bearing assemblies

or the hub caps, as this excessive lubrication results in

the lubricant working out into the brake drums and

linings.

Front wheels of all passenger car models are equipped

with tapered roller bearings and should be packed with a

high melting point water resistant front wheel bearing

lubricant whenever wheel and hub are removed.

CAUTION: "Long fibre" or "viscous" type

lubricant should not be used. Do not mix wheel

bearing lubricants. Be sure to thoroughly clean

bearings and hubs of all old lubricant before

repacking.

The proper adjustment of front wheel bearings is one

of the important service operations- that has a definite

bearing on safety. A car with improperly adjusted front

wheel bearings lacks steering stability, has a tendency to

wander or shimmy and may have increased tire wear.
The adjustment of these bearings is very critical. The

procedure is covered in Section 3 of this manual under

Front Wheel Bearings—Adjust,

MANUAL STEERING GEAR

Check lubricant level every 36,000 miles. If required,

add EP Chassis Lubricant.

POWER STEERING

On models equipped with power steering gear, check

fluid at operating temperature in pump reservoir. Add

GM Power Steering Fluid, or, if this is not available, use

Automatic Transmission Fluid "Type A" bearing the

mark AQ-ATF followed by a number and the suffix letter

'A'
to bring level to full mark on dip stick.

AIR CONDITIONING

After the first 6,000 miles, check all hose clamp

connections for proper tightness.

Every 6,000 miles check sight glass under the hood,

after the system has been in operation for several

minutes. Sight glass should be clear but may, during

milder weather, show traces of bubbles. Foam or dirt

indicate a leak which should be repaired immediately.

BRAKE MASTER CYLINDER

Check level every 6,000 miles and maintain 1/4" below

lowest edge of each filler opening with GM Hydraulic

Brake Fluid Supreme No. 11.

PARKING BRAKE

Every 6,000 miles, apply water resistant lube to park-

ing brake cable, cable guides and at all operating links

and levers.

CLUTCH CROSS-SHAFT

Periodic lubrication of the clutch cross shaft is not

required. At 36,000 miles or sooner, if necessary;

remove plug, install lube fitting and apply CHASSIS

LUBRICANT.

CHASSIS LUBRICATION

For chassis lubrication, consult the lubrication chart.

It shows the points to be lubricated and how often the

lubricant should be applied.

The term "chassis lubricant" as used in this manual,

describes a water resistant EP chassis grease designed

for application by commercial pressure gun equipment.

ENGINE-EIECTRICAI 6Y-3

PERIODIC SERVICING

Since the Battery is a perishable item which requires

periodic servicing, a good maintenance program will

insure the longest possible Battery life.

COMMON CAUSES OF FAILURE

If the Battery tests good but fails to perform satis-

factorily in service for no apparent reason, the following

are some of the more important factors that may point to

the cause of the trouble.

1.
Vehicle accessories inadvertently left on overnight to

cause a discharged condition.

2.
Slow speed driving of short duration, to cause an

3.
undercharged condition.

A vehicle

capacity.
electrical load exceeding the generator

4.
Defect in the charging system such as high resist-

ance, slipping fan belt, faulty generator or voltage

regulator.

5. Battery abuse, including failure to keep the Battery

top clean, cable clamps and posts clean and tight,

and improper addition of water to the cells.

LEVEL INDICATOR

The Battery features an electrolyte level indicator,

which is a specially designed vent plug with a transparent

rod extending through the center (fig. 5b). When the elec-

trolyte is at the proper level, the lower tip of the rod is

immersed, and the exposed top of the rod will appear

very dark; when the level falls below the tip of the rod,

the top will glow. ,

The Indicator reveals at a glance if water is needed,

without the necessity of removing the vent plugs (fig. 6b).

The Level Indicator is used in only one cell (second

cell cap from positive Battery post) because when the

electrolyte level is low in one cell, it is normally low in

all cells. Thus when the Indicator shows water is needed,

check the level in all six cells.

An alternate method of checking the electrolyte level is

to remove the vent plug and visually observe the electro-

lyte level in the vent well. The bottom of the vent well

features a split vent which will cause the surface of the

electrolyte to appear distorted when it makes contact.

The electrolyte level is. correct when the distortion first

appears at the bottom of the split vent (fig. 4b).

ELECTROLYTE LEVEL

The electrolyte level in the Battery should be checked

regularly. In hot weather, particularly during trip driv-

ing, checking should be more frequent because of more

rapid loss of water. If the electrolyte level is found to be

low, then colorless, odorless, drinking water should be

added to each cell until the liquid level rises to the split

vent located in the bottom of the vent well. DO NOT

OVERFILL because this will cause loss of electrolyte

resulting in poor performance, short life, and excessive

corrosion.

CAUTION: During service only water should be

added to the Battery, not electrolyte.

The liquid level in the cells should never be allowed to

drop below the top of the plates, as the portion of the

plates exposed to air may be permanently damaged with a

resulting loss in performance.

WATER USAGE

Excessive usage of water indicates the Battery is being

overcharged. The most common causes of overcharge

are high Battery operating temperatures, too high a volt-

age regulator setting, poor regulator ground wire con-

nection. Normal Battery water usage is approximately

one to two ounces per month per battery.

CLEANING

The external condition of the Battery should be checked

periodically for damage or for the presence of dirt and

corrosion. The top of the Battery should be kept clean.

An accumulation of acid film and dirt may permit current

to flow between the terminals, which will slowly dis-

charge the Battery. For best results when cleaning the

top of Batteries, wash first with a diluted ammonia or a

soda solution to neutralize any acid present; then flush

with clean water. Care must be taken to keep vent plugs

tight, so that the neutralizing solution does not enter the

cells.

CABLES

To insure good electrical contact, the cables should be

clean and tight on the Energizer posts. If the posts or

cable terminals are corroded, the cables should be dis-

connected and the terminals and clamps cleaned sepa-

rately with a soda solution and a wire brush. After

cleaning and installing clamps, apply a thin coating of

petroleum jelly on the cable clamps to retard corrosion.

CARRIER
AND
HOLD-DOWN

The Battery carrier and hold-down should be clean and

free from corrosion before installing the Battery. The

carrier should be in a sound mechanical condition so that

it will support the Battery securely and keep it level.

To prevent the Battery from shaking in its carrier,

the hold-down bolts should be tight (60-80 in. lbs.). How-

ever, the bolts should not be tightened to the point where

the Battery case or cover will be placed under a severe

strain.

BATTERY SAFETY PRECAUTIONS

When Batteries are being charged, an explosive gas

mixture forms in each cell. Part of this gas escapes

through the holes in the vent plugs and may form an

explosive atmosphere around the Battery itself if ventila-

tion is poor. This explosive gas may remain in or around

the Battery for several hours after it has been charged.

Sparks or flames can ignite this gas causing an internal

explosion which may shatter the Battery.

The following precautions should be observed to pre-

vent an explosion:

1.
Do not smoke near Batteries being charged or which

have been very recently charged.

2.
Do not break live circuits at the terminals- of Batr

teries because a spark usually occurs at the point

where a live circuit is broken. Care must always be

taken when connecting or disconnecting booster leads

or cable clamps on fast chargers. Poor connections

are a common cause of electrical arcs which cause

BATTERY CHARGING PROCEDURES

There are three methods of recharging Batteries.

They differ basically in the length of time the Battery is

charged and the rate at which charging current is sup-

plied. One is the Slow Charge method, the second is the

Fast Charge method, and the third is the Emergency

Boost Charge method.

Before recharging a Battery by any method, the elec-

trolyte level must be checked and adjusted if necessary.
SLOW CHARGING

The Slow Charge method supplies the Battery with a

relatively low current flow for a relatively long period of

time. This is the only method that will bring the Battery

to a full state of charge.

The Slow Charge method consists of charging at

approximately a 4 ampere rate for 24 hours or more if

necessary to bring the Battery to full charge. A fully

charged condition is reached when the cells are gassing

freely and three corrected specific gravity readings

taken at hourly intervals show no increase.

FAST CHARGING

The Fast Charge method supplies current to the Bat-

tery at a 40 to 50 ampere rate for a 1 1/2 hour period of

time. If the electrolyte temperature reaches 125°F before

the 1 1/2 hour period is completed, the Battery must be

taken off charge temporarily, or the charging rate

reduced to avoid damage to the Battery.

Although a Battery cannot be brought to a fully charged

condition during Fast Charge, it can be substantially

recharged or "boosted". In order to bring the Battery to

a fully charged condition, the charging cycle must be

finished by the Slow Charge method.

EMERGENCY BOOST CHARGING

In cases where the Battery is not sufficiently charged

to crank the engine, an emergency boost charge may be

applied as a temporary expedient in order to crank the

engine. The Emergency Boost Charge method consists of

charging at a 40 to 50 ampere rate for a period of one-

half hour.

It should be particularly noted that the Emergency

Boost Charge will not necessarily restore the Battery to

a useful state of. charge for continued service. After an

emergency boost charge, failure to charge the Battery

further, either by a long uninterrupted driving period or

by the Fast Charge or Slow Charge method, may result

in failure to crank the engine the next time cranking is

attempted. A Battery should never be condemned on the

basis of failure to crank the engine after an emergency

boost charge. Although an emergency boost charge may

put enough energy into the Battery to crank the engine

once, further charging usually is necessary in order to

create a sufficient reserve to crank a second and third

time.

FUSIBLE LINK'

Fig.
4c— Circuitry - Voltage Regulator Assemblies (Corvette)

Engine compartment wiring harness incorporates sev-

eral fusible links. Each link is identified with its gage

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

four wire gages 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 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 gage, brown fusible link protecting

the 10 gage battery charging circuit. This wire is an

integral part of the battery cable assembly and serv-

icing 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 gage black fusible link is located at the horn
4.
relay to protect all unfused wiring of 12 gage or

larger. It is installed as a molded splice and serv-

icing requires splicing in a new link.

The generator warning light and field circuitry (16

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

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 gage

wire as required.

The ammeter circuit on all models is protected by

two orange, 20 gage 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 gage wire as required.

MAINTENANCE AND ADJUSTMENTS

At regular intervals, inspect the terminals for cor-

rosion an4 loose connections, and the wiring for frayed

insulation. Check mounting bolts for tightness. Check the

drive belt for alignment, proper tension and wear. Be-

cause of the higher inertia and load capacity of the rotor

used in A.C. generators, PROPER BELT TENSION is

more critical than on D.C. generators.

Since the Delcotron and its companion regulator are

designed for use on negative polarity systems only, the

following precautions must be observed. Failure to ob-

serve these precautions may result in serious damage to

the charging system.

1.
When installing a battery, always make absolutely

sure the ground polarity of the battery, generator and

regulator is the same.

2.
When connecting a booster battery, make certain to

connect the correct battery terminals together.

3.
When connecting a charger to the battery, connect the

correct charger leads to the battery
%
terminals.

4.
Never operate the generator on an uncontrolled open

GENERAL DESCRIPTION

WHEELS

Chevrolet, Chevelle, Camaro, Chevy n, and Corvette

are base equipped with welded steel wheels. Five studs

with nuts fasten each wheel to the front hub or rear axle

flange. Disc brake equipped vehicles (except Chevrolet

and Corvette) require special 14 inch diameter wheels

with a revised design for clearance, Chevrolet disc brake

equipped vehicles have 15 in. diameter wheels as do all

Corvettes.

Chevrolet station wagons, Chevelle Super Sport 396,

Corvette and Camaro Super Sport 350 are base equipped

with 6 in. width wheels. All other vehicles have 5 in.

width wheels, except Chevy n 100, 300 and 500 Series

Sedans, which have 4 in. width wheels.

Do not install 6 inch width wheels or snow chains on

Chevrolets equipped with rear fender skirts.

TIRES

The factory installed tires on Chevrolet passenger

cars are selected to provide the best all around tire

performance for all normal operation. They are de-

signed to operate satisfactorily with loads up to and in-

cluding the specified full rated load capacity of the
automobile when inflated as recommended in the Vehicle

Capacity Rating and Recommended Tire Inflation Pres-

sures Table (see Specifications).

Optional Oversize and 8-Ply Rating Tires

{Chevrolet and Chevelle Only)

Oversize or 8-ply rating tires are not necessary on

passenger cars for normal requirements. However, an

extra margin of tire service is available when these

options are used at loads up to and including full rated

load.

Optional oversize 4-ply rating and/or 8-ply rating

tires are available on models as indicated in the Tire

Usage Chart (see Specifications). On some models (ex-

ample—Station Wagon), space limitations do not permit

the use of a larger size tire; hence, the 8-ply rating

tire is an available option.

In either case, these tires are applicable to extended

operation at or near full rated load or for trailer towing

when an extra margin of tire service is desired. How-

ever, use of a larger tire or an 8-ply rating tire should

not be construed as permitting an increase in the full

rated vehicle load (see Specifications).

MAINTENANCE AND ADJUSTMENTS

TIRES

Inflation Pressures

To ensure the proper tire inflation pressure for the

owners particular requirements follow the recommenda-

tions in the Vehicle Capacity Rating and Recommended

Tire Inflation Pressures Table (seeSpecifications). Keep

tires properly inflated, and check inflation pressures

periodically. This will ensure the best tire life and riding

comfort, over the full range of driving conditions.
Inspection

Every few thousand miles and at each lubrication, tires

should be checked for sharp objects or stones in the

tread. H tire is punctured, it should be repaired using

one of several repair kits available through tire manu-

facturers1 outlets.

Wear

Misalignment

This is wear due to excessive toe-in or toe-out. In
