GENERAL DESCRIPTION

The single exhaust system
cm
six* cylinder engine

models
(fig. 36)
consists
of an
exhaust pipe, extension,

muffler
and
tailpipe with necessary attaching brackets

and clamps.
On V-8
engine models with single exhaust

assemblies
(fig. 36) an
exhaust crossover pipe
is
added

to connect
the
right exhaust manifold
to the
system.
The

dual exhaust system available
on V-8
engine models
(fig.

37) includes
two
front exhaust pipes -with
or
without

resonators,
two
rear exhaust pipes, dual inlet-outlet

muffler, tailpipes and attaching hardware.

The assemblies
are
secured
to the
engine
at the ex-

haust manifolds,
to the
rear compartment pan reinforce-

ment ahead
of
axle
and
adjacent
to the gas
tank
at the
end
of the
tailpipe.
The
assemblies
are
suspended
on

brackets with insulators
for
rattle free operation.

The muffler
is an
all-welded construction with
a

•
capacity
for
muffling
the
noise
and at the
same time,

minimizing back pressure
for
maximum engine effici-

ency.
The
internal parts
are
electric welded
to
eliminate

premature failure
or
rattle.

The exhaust system center mounting
at the
muffler

location consists
of an
underbody bracket,
an
insulator

and
a
clamp.
The
clamp holds
the
muffler and tailpipe

with
a
"U" bolt and
at
the same time secures
the
muffler

and pipe
to the
body.

The exhaust system mounting
at the
end
of
the tailpipe

secures
the
pipe
to a
bracket assembly
and
insulator

attached
to an
existing underbody bracket.

GENERAL DESCRIPTION

The regular production steering gear
is the
recirculat-

ing ball type. This gear provides
for
ease
of
handling
by

transmitting forces from worm
to
sector gear through

ball bearings.
The
steering linkage
is of
the relay type,

and extended interval lubrication design, with the pitman

arm connected
to one end of
the relay
rod. The
other
end

of
the
relay
rod is
connected
to an
idler
arm
which
is

connected
to the
frame side rail opposite
the
steering
gear.
Two
adjustable
tie
rods connect
the
relay
rod to

the steering arms.

All passenger
car
models
for 1967 are
equipped with

new energy absorbing steering columns.
The
mast jacket,

shift tube,
and
steering shaft
are
designed
to
collapse

under various front impact conditions.
All new
columns

are
of
this design, including
the
tilt option and telescope

option.

MAINTENANCE
AND
ADJUSTMENTS

The manual steering gear
is
filled
at the
factory with
a

water resistant grease. Seasonal change
of
this lubrica-

tion
is
unnecessary and
the
housing should
not be
drained.

The steering gear lubricant level should
be
checked every

36,000 miles. Whenever required, additions should
be

made using
a
water resistant
EP
chassis lubricant.

Check and fill steering gear
as
follows:

1.
Remove lower
and
outboard cover retaining screws

(fig.
1).
2.
Insert filling device
in
lower screw hole.

3.
Inject lubricant until
it
appears
in
outboard screw

hole; gear
is now
filled
to
correct level.

The steering linkage should
be
lubricated with water

resistant
EP
chassis lubricant every 6,000 miles
or six

months, whichever occurs first. Lubrication points
and

additional information
on the
chassis lubricant
to be
used

can
be
found
in
Section
0 --
General Information
and

Lubrication.

ADJUSTMENTS

STEERING
GEAR

Before any adjustments are made to the steering gear

in an attempt to correct such conditions as shimmy,

loose or hard steering etc., a careful check should be

made of front end alignment, shock absorbers, wheel

balance and tire pressure for possible cause.

Correct adjustment of the steering gear is very im-

portant. Perform adjustments following the sequence

listed below,

1.
Remove pitman arm nut and mark relation of pitman

arm position to sector shaft. Remove pitman arm

with Tool J- 6632 as shown in Figure 2.

2.
Loosen the pitman shaft lash adjuster screw locknut

and turn the adjuster screw a few turns in a counter-

clockwise direction (fig. 3). This removes the load
Fig. 2—Removing Pitman Arm

imposed on the worm bearings by the close meshing

of rack and sector teeth. Turn steering wheel gently

in one direction until stopped by gear, then back away

about one turn.

CAUTION: Do not turn steering wheel hard

against stops when steering relay rod is discon-

nected as damage to ball guides may result.

3.
All except Corvette and telescopic columns:

a. Disconnect steering column harness at chassis

wiring connector plug.

b.
Remove horn cap or ornament and using an inch

pound torque wrench and socket on steering wheel

nut, measure torque required to keep the wheel

in motion.

c. If torque does not lie within limits given in speci-

fications at rear of manual, adjustment is

necessary.

4.
Corvette and telescopic columns:

a. Use Tool J-5178 to measure.pull at rim of wheel

required to keep wheel in motion (fig. 4).

b.
If pull does not lie within limits given in specifi-

cations in rear of manual, adjustment of worm

bearings is necessary.

NOTE:
If vehicle is equipped with a tilt steer-

ing column, it will be necessary to disconnect

the steering coupling to obtain a torque reading

of the steering column. This torque should then

be subtracted from any reading taken on the

gear.

5. To adjust worm bearings, loosen worm bearing ad-

juster locknut and turn worm bearing adjuster shown

in Figure 3 until there is no perceptible end play in

worm. Check pull at steering wheel, readjusting: if

necessary to obtain proper pull. Tighten locknut and

recheck pull. If the gear feels "lumpy" after adjust-

ment of worm bearings, there is probably damage in

the bearings due to severe impact or to improper

adjustment and the gear must be disassembled for

replacement of damaged parts.

6. After proper adjustment of worm is obtained and all

mounting bolts securely tightened, adjust lash ad-

juster screw. First turn the steering wheel gently

from one stop all the way to the other, carefully

counting the total number of turns. Then turn wheel

back exactly half way, to center position. Turn lash

adjuster screw clockwise to take out all lash in gear

teeth, and tighten locknut. Check pull at steering

wheel taking highest reading as wheel is turned

through center position. See specifications in rear of

manual for proper sector lash adjustment. Readjust

if necessary to obtain proper pull.
NOT MORE THAN

T/a INCH FROM

CENTERLINE

NOTE:
If maximum specification is exceeded,

turn las£ adjuster screw counterclockwise, then

come up on adjustment by turning the adjuster in

a clockwise motion.

7. Tighten locknut then recheck pull, as it must lie be-

tween specified readings.

8. Reassemble pitman arm to sector shaft, lining up

marks made during disassembly. Refer to torque

specifications at rear of manual for correct torque

value.

9. Install horn cap or ornament and connect steering

column harness at chassis connector.

NOTE:
Chevy.n models are equipped with a

shim at the frame to steering gear mounting

bolts.
Shims may be removed or installed as

required for proper steering gear alignment.

STEERING WHEEL ALIGNMENT AND

HIGH POINT CENTERING

1.
Set front wheels in straight ahead position. This can

be checked by driving vehicle a short distance on a

flat surface to determine steering wheel position at

which vehicle follows a straight path.

2.
With front wheels set straight ahead, check position

of mark on wormshaft designating steering gear high

point. This mark should be at the top side of the shaft

at 12 o'clock position and lined up with the mark in

the coupling lower clamp.

3.
If gear has been moved off high point when setting

wheels in straight ahead position, loosen adjusting

sleeve clamps on both left and right hand tie rods,

then turn both sleeves an equal number of turns in

the same direction to bring gear back on high point.

CAUTION: Turning the sleeves an unequal
number of turns or in differential directions will

disturb the toe-in setting of the wheels.

4.
Readjust toe-in as outlined in Section 3 (if necessary).

5. With wheels in a straight ahead position and the

steering gear on highpoint, check the steering wheel

alignment by measuring the distance from each hori-

zontal spoke to the horizontal centerline of the

steering wheel (fig. 5). If the horizontal spokes are

over 1-1/8 inches from the horizontal position the

wheel should be removed and centered. (See steering

wheel removal in this section.)

TOE-IN ADJUSTMENT

Adjust the steering linkage for proper toe-in setting as

outlined in Section 3.

CORVETTE STEERING RATIO (Fig. 6)

The Corvette steering ratio may be changed as follows:

CAUTION: Do not use the rearward hole in the

steering arm with power steering equipment or

interference may result.

1.
Remove tie rod ball stud nut at steering arm and

disconnect tie rod from steering arm.

2.
Move tie rod end to forward hole for 17.6:1 ratio

(fast ratio) or rear hole for 20.2:1 ratio (standard

ratio).

3.
Install tie rod stud nut and tighten securely. Repeat

operation on opposite steering arm.
