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

Fig.
65— Checking Belt Tension with Tool J-7316

CHEVROLET CHASSIS SERVICE MANUAL

STEERING 9-35

Fig.
66—Power Steering Diagnosis

shown in Figure 66. Gauge must be between shut-

off valve and pump. Open shut-off valve,

b.
Remove filler cap from pump reservoir and check

fluid level. Fill pump reservoir to full mark on

dip stick. Start engine and, holding steering

wheel against stop, check connections at Tool

J-5176 for leakage. Bleed system as outlined
under Maintenance and Adjustments. Insert ther-

mometer (Tool J-5421) in reservoir filler open-

ing. Move steering wheel from stop to stop

several times until thermometer indicates that

hydraulic fluid in reservoir has reached tempera-

ture of 150° to 170°F.

CAUTION: To prevent scrubbing flat spots on

tires,
do not turn steering wheel more than five

times without rolling car to change tire-to-floor

contact area.

c. Hold steering wheel against a stop momentarily

and read pressure gauge. If the maximum pres-

sure is below specifications, a faulty hydraulic

circuit is indicated. To determine which part is

faulty, proceed with test number two.

Test Number Two—Oil Circuit Closed

a. Slowly turn shut-off valve on J-5176 to closed

position and read pressure indicated on gauge.

Quickly reopen valve to avoid pump damage, if

indicated pressure is less than specification,

pump output is below requirement and pump may

be considered faulty. If pressure indicated is

within specifications, it may be safely assumed

that the external hoses, connections, valve and

adapter or steering gear is at fault.

NOTE:
If pump proves faulty in test number

two,
test should be repeated after pump is re-

paired and installed in vehicle. This will provide

a means of checking the repairs made to the

pump and the condition of the steering gear or

valve and adapter which may also be faulty.

COMPONENT REPLACEMENT AND REPAIRS

POWER STEERING PUMP

Removal (Fig. 67)

1.
Disconnect hoses at pump. When hoses are discon-

nected, secure ends in raised position to prevent

drainage of oil. Cap or tape the ends of the hoses to

prevent entrance of dirt.

NOTE:
Chevelle with 396 engine uses a remote

reservoir. It is necessary to disconnect the

reservoir to pump hose before removing the

pump.
Hold a 1 qt. container under the reservoir

when the hose is removed to catch the fluid.

2.
Install two caps at pump fittings to prevent drainage

of oil from pump.

3.
Remove pump belt.

4.
On Corvette with 427 engine, loosen alternator ad-

justment and remove pump to alternator belt.

5. Remove pump from attaching parts and remove pump

from vehicle.

NOTE:
On Chevrolet and Chevy II equipped with

283 and 327 engine it may be necessary to re-

move pump brace.

6. Remove drive pulley attaching nut.

7. Remove pulley from shaft with Tool J-21239 (for

stamped pulleys) or Tool J-8433-1 with J-8433-2
adapter (for cast iron pulleys). Do not hammer

pulley off shaft as this will damage the pump.

pulley nut to pull pulley on to shaft.

2.
Position pump assembly on vehicle (Fig. 67) and in-

stall attaching parts loosely.

3.
Connect and tighten hose fittings.

4.
Fill reservoir. Bleed pump by turning pulley back-

ward (counterclockwise as viewed from front) until

air bubbles cease to appear.

5. Install pump belt over pulley.

6. Tension belt as outlined under "Pump Belt Tension

Adjustment" in this section.

7. Bleed as outlined under "Maintenance and

Adjustments."

POWER STEERING GEAR (Fig. 68)

Chevrolet,
Chevelfe,

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.)

POWER STEERING HOSES

When servicing the power steering hoses be sure to

align the hoses in their correct position as shown in

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.
