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.
Chevy II and Corvette

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

Replacement procedures for the power steering gear

are the same as for the manual type steering gear.
•
Refer

to steering gear procedures near the beginning of this

section under "Component Replacement and Repairs".
In addition, disconnect pressure and return hoses from

the steering gear housing. Cap both hoses and steering

gear outlets to prevent foreign material from entering

the system. After service is performed and steering gear

is installed, connect the pressure and return hoses to

the steering gear housing. Bleed system as outlined

under Maintenance and Adjustment in this section. Refer

to torque specifications at rear of manual for correct

torque values.

CONTROL VALVE AND ADAPTER ASSEMBLY

Chevy II and Corvette

Ball Stud Seal Replacement (Fig. 69)

A ball stud seal is used on the power steering control

valve. To replace the seal:

1.
Remove the pitman arm as outlined under "Steering

Linkage" in this section.

2.
Remove clamp by removing nut, bolt and spacer or,

if crimped type clamp is used, straighten clamp end

and pull clamp and seal off end of stud.

3.
Install new seal and clamp over stud so lips on seal

mate with clamp. (A nut and bolt attachment type

clamp replaces the crimped type for service.)

WHEELS AND TIRES 10-4

the road and it slips, grinding off the tread on the inside

half of the tire at an excessive rate. This type of tire

shows much the same appearance of tread wear as tire

wear caused by negative camber.

Second, the transfer of weight may also over-load the

outside tires so much that they are laterally distorted

resulting in excessive wear on the outside half of the

tire producing a type of wear like that caused by ex-

cessive positive camber.

Cornering wear can be most easily distinguished from

abnormal camber wear by the rounding of the outside

shoulder or edge of the tire and by the roughening of the

tread surface which denotes abrasion.

Cornering wear often produces a fin or raised portion

along the inside edge of each row in the tread pattern.

In some cases this fin is almost as pronounced as a

toe-in fin, and in others, it tapers into a row of tread

blocks to such an extent that the tire has a definite step

wear appearance.

The only remedy for cornering wear is proper in-

struction of owners.

Fig.
5 - Tire Rotatidh

Rotation

To minimize the possibility of tire noise and to equal-

ize tire wear, it is recommended that tires be inter-

changed every 6000 miles as shown in Figure 5 or more

frequently in the case of extremely heavy wear.

NOTE:
Rotate Corvette tires at 4000 miles or

sooner.

Interchanging tires will effectively prevent undue wear

on any particular tire. II tire interchanging is followed

as recommended above, all tires will have the same

number of miles in each wheel position at the end of the

fourth change. When interchanging tires, inspect for

signs of abnormal wear, bulging, etc., stones, glass, and

nails should be removed before reinstallation.

Noise

Noise caused by the normal action of tire treads on

various road surfaces is often confused with rear axle
gears or other noises in the car.

The determination of whether tires are causing the

noise complained of is relatively simple. The car should

be driven at various speeds and note taken of part

throttle, and sudden acceleration and deceleration. Axle

and exhaust noises show definite variations under these

conditions, while tire noise will remain constant. Tire

noise is, however, most pronounced at speeds of approx-

imately twenty or thirty miles per hour.

The tires may be further checked by driving the ear

over smooth pavement with the tires at normal pressure

and again over the same stretch of pavement when the

tires have been inflated to fifty pounds pressure. Reduce

the tires to normal pressure one at a time to determine

the faulty tire or tires. This high inflation pressure

should immediately be reduced to normal after test. If

the noise for which the test is being made is caused by

tires,.
it will noticeably decrease when the tire pressure

is increased, whereas axle noise should show no change

in volume.

If, on inspection, the tires on the front wheels are

found to be creating most of the noise the alignment of

the front wheels should be checked. Excessive tire noise

usually results from lower than recommended tire pres-

sure, incorrect alignment, uneven tire wear, or defective

(thumper) tire.

Cleaning

A great deal of ordinary road dirt which collects on

white sidewall tires may be sponged off with clear water

or a mild soap solution.

A good brand of whitewall tire cleaner, however, is

a quicker and more effective cleaner for removing dirt

and stains from whitewall tires and in many cases it

will remove stains and discoloration that the simpler

method of soap and water will not remove.

Under no circumstances should gasoline, kerosene or

any cleaning fluid containing a solvent derived from oil

be used to clean whitewall tires. Oil in any form is

detrimental to tire rubber and a cleaner with an oil base

will discolor or injure whitewall tires.

Change (W/Wheels)

To change the road wheels using the jack that comes

with the car, observe the following procedure:

1.
Set hand brake and block front wheels if rear wheel

is being changed.

2.
Remove hub cap or wheel disc and break wheel

mounting nuts loose.

3.
Place the jack as directed tinder, General Informa-

tion,
Section 0 and raise car until wheel clears

ground.

4.
Remove wheel mounting nuts and remove wheel from

hub or drum.

5. To replace road wheel, reverse the above instrue-

. tions. Proper torque on nuts is 55-75 ft. lbs.

torque (70-85 ft. lbs. for Corvette aluminum wheel

nuts).

CAUTION: On models equipped with discs, in-

dex the pilot hole in the disc on the valve stem.

(To insure that the anti-rotation notches in wheel

disc register on lugs in wheel rim.)
