SERVICE ADJUSTMENT
PROCEDURE |
CHECKING STEERING WHEEL FREE PLAY
1. |
Start the engine with the steering wheel in
the straight ahead position. |
2. |
Measure the play at the circumference of the
steering wheel.
Standard
value
Steering wheel free play : 0~30 mm
(0~1.1 in)
|

|
3. |
If the play exceeds the standard value,
inspect the connection between the steering shaft and steering
linkage. |
CHECKING STEERING ANGLE
1. |
Place the front wheel on a turning radius
gauge and measure the steering angle.
Standard
value
Wheel angle
Inner wheel : 34°76´ ± 2°
Outer wheel : 30°19´
|

|
2. |
If the measured value is not within the
standard value, adjust the toe and inspect
again. |
CHECKING THE TIE ROD END BALL JOINT STARTING
TORQUE
1. |
Disconnect the tie rod and knuckle by using
the special tool.

|
2. |
Move the ball joint stud in a circular motion
several times to check for
looseness. |
3. |
Mount the nuts on the ball joint, and then
measure the ball joint starting torque.
Standard
value
0.5~2.5 Nm (5~25 kg•cm, 0.36~1.78
lb•ft)
|

|
4. |
If the starting torque exceeds the upper limit
of the standard value, replace the tie rod
end. |
5. |
Even if the starting torque is below the lower
limit of the standard value, check the play of the ball joint and
replace if necessary. |
CHECKING STATIONARY STEERING EFFORT
1. |
Position the vehicle on a level surface and
place the steering wheel in the straight ahead
position. |
2. |
Increase the engine speed to 1000 ± 100
rpm.
After checking, reset the engine speed
to the standard value (idling
speed). | |
3. |
Measure the turning force with a spring scale
by turning the steering wheel clockwise and counterclockwise one and
a half turns.
Standard
value
Stationary steering effort : 29 N (3.0
kg, 6.5lbs)
| |
4. |
Check that there is no sudden change of force
while turning the steering wheel. |
5. |
If the stationary steering effort is
excessive, check and adjust the following points.
(1) |
Damage or cracks on the dust cover and
tie rod end ball joint. |
(2) |
Pinion preload of the steering gear box
and starting torque of the tie rod end ball
joint. |
(3) |
Starting torque of the ball
joint. | |
CHECKING STEERING WHEEL RETURN
1. |
The force required to turn the steering wheel
and the wheel return should be the same for both left and right in
case of moderate or sharp turns. |
2. |
When the steering wheel is turned 90° and held
for a couple of seconds while the vehicle is being driven at 35kph,
the steering wheel shouldreturn at least 70° from the neutral
position when it is released.
If the steering wheel is turned very
quickly, steering may be momentarily difficult. This is not a
malfunction because the oil pump output will be
somewhatdecreased. |

|
CHECKING POWER STEERING BELT TENSION
1. |
Press the V belt, applying a pressure of 98N
(10kg, 22lb) at the specified point and measure the deflection to
confirm that it is within the standardvalue.
Standard
value
V belt deflection
New belt : 8.8~11.0mm (0.35~0.43
in)
Used belt : 12.5~14.3mm (0.49~0.56
in)
|

|
2. |
If the belt deflection is beyond the standard
value, adjust the belt tension as follows.
(1) |
Loosen the bolt adjusting the power
steering "V" belt tension.

|
(2) |
Put a bar or equivalent, between the
bracket and the oil pump and adjust the tension so that the
belt deflection is within the standard value.

|
(3) |
Tighten the bolt adjusting the power
steering "V" belt tension. |
(4) |
Check the belt deflection and adjust it
again if necessary.
After turning the V belt in the
normal rotation direction more than once, recheck the
belt
deflection. | | |
CHECKING POWER STEERING FLUID LEVEL
1. |
Position the vehicle on a level
surface. |
2. |
Start the engine. With the vehicle kept
stationary, turn the steering wheel several times continuously to
raise the fluid temperature to 50~60°C (122 to
140°F). |
3. |
With the engine at idle, turn the steering
wheel fully clockwise and counterclockwise several
times. |
4. |
Make sure there is no foaming or cloudiness in
the reservoir fluid. |
5. |
Stop the engine to check for any difference in
fluid level between a stationary and a running engine.
1. |
If the fluid level varies 5mm (0.2
in) or more, bleed the system
again. |
2. |
If the fluid level suddenly rises
after stopping the engine, further bleeding is
required. |
3. |
Incomplete bleeding will produce a
chattering sound in the pump and noise in the flow
control valve, and lead to decreased durability of the
pump. | |

|
REPLACING POWER STEERING FLUID
1. |
Jack up the front wheels and support them with
rigid racks. |
2. |
Disconnect the return hose from the oil
reservoir and plug the oil
reservoir. |
3. |
Connect a vinyl hose to the disconnected
return hose, and drain the oil into a
container. |
4. |
Disconnect the high-tension cable at the
ignition coil side.
While operating the starter motor
intermittently, turn the steering wheel all the way to the left and
then to the right several times to drain the
fluid. |
5. |
Connect the return hose and fix it with a clip
securely. |
6. |
Fill the power steering fluid reservoir with
the specified fluid.
|
8. |
Check for fluid leaks from the hose, then stop
the engine. |
9. |
Pour the fluid into the bottom of the oil
filter in the power steering fluid
reservoir. |
AIR BLEEDING
1. |
Disconnect the ignition coil high tension
cable, and then, while operating the starter motor intermittently
(for 15 to 20 seconds), turn the steering wheel all the way to the
left and then to the right five or six times.
1. |
During air bleeding, replenish
with the fluid so that the level does not fall below the
lower position of the
filter. |
2. |
If air bleeding is done while the
vehicle is idling, the air will be broken up and
absorbed into the fluid. Be sure to do the bleeding only
while
cranking. | | |
2. |
Connect the high tension cable, and then start
the engine (idling). |
3. |
Turn the steering wheel to the left and then
to the right, until there are no air bubbles in the oil
reservoir. |
4. |
Confirm that the fluid is not milky and that
the level is between "MAX" and "MIN" marks on the
reservoir. |
5. |
Check that there is a little change in the
fluid level when the steering wheel is turned left and
right.
1. |
If the fluid level varies 5mm (0.2
in.) or more, bleed the system
again. |
2. |
If the fluid level suddenly rises
after stopping the engine, further bleeding is
required. |
3. |
Incomplete bleeding will produce a
chattering sound in the pump and noise in the flow
control valve, and lead to decreased durability of the
pump. | |

|
OIL PUMP PRESSURE TEST
1. |
Disconnect the pressure hose from the pump.
Connect the special tool between the pump and the pressure hose as
illustrated.

|
2. |
Bleed the air, and then start the engine and
turn the steering wheel several times so that the fluid temperature
can rise to approximately 50~60°C (122~132°F) operating
temperature. |
3. |
Increase the engine speed to 1,000 ± 100
rpm. |
4. |
Close the shut-off valve of the special tool
and measure the fluid pressure to confirm that it is within the
standard value range.
Standard
value
Relief pressure :
8.3~8.8 MPa (85~90 kg.cm², 1209~1280
psi)
|
Do not keep the shut-off valve on the
pressure gauge closed for more than ten
seconds. | |
5. |
Remove the special tools, and tighten the
pressure hose to the specified torque.
Tightening
torque
55~65 Nm (550~650 kg•cm, 40.6~47.9
lb•ft)
