STEERING WHEEL PLAY
With the wheels in the straight-ahead position, gent-
ly turn the steering wheel to the left and right and
check that the play is within specification.
Play: 0—30 mm (0—1.18 in)
Note
If play exceeds specification, either the steer-
ing joints are worn or backlash of the steer-
ing gear is excessive.
LOOSENESS OR PLAY OF STEERING WHEEL
Move the steering wheel in the directions ©, ©, and
© to check for column bearing wear, steering-shaft
joint play, steering wheel looseness, and column
looseness.

STEERING WHEEL EFFORT
Manual Steering
1. Jack up the vehicle. Move the steering wheel to
put the wheels in the straight-ahead position.
2. Measure the steering wheel effort by connecting
a pull scale to the outer circumference of the steer-
ing wheel.
Steering wheel effort:
5—25 N (0.5—2.5 kg, 1—5.5 lb)
[during one turn of the steering wheel]
Note
Measure after turning the steering wheel to
the left and right at least 5 times.
3. If the measured value exceeds specification, check
the following: rotation-starting torque of pinion, ro-
tation torque of each ball-joint, and joints.

Adjustment
Gasoline engine
1. Loosen the lock nut on the idler pulley.
2. Turn the adjust bolt on the idler pulley until the cor-
rect tension is obtained.
3. Tighten the lock nut and recheck the tension.
Tightening torque:
49—59 Nm (5—6 m-kg, 36—43 ft-lb)
Diesel engine
1. Loosen the vacuum pump bolt ©and (B).
2. Lever the vacuum pump outward and apply ten-
sion to the belt.

POWER STEERING PRESSURE
1. Disconnect the high-pressure hose of the gear
housing side, and attach the SST.
Tightening torque:
39—49 N-m (4.0—5.0 m-kg, 29—36 ft-lb)
2. Bleed air from the system.
3. Open the gauge valve fully, then start the engine
and turn the steering wheel fully left and right to
raise the fluid temperature to 50—60°C
(122—140°F)
4. To measure the fluid pressure generated by the
oil pump, close the gauge valve completely and
increase the engine speed to 1,000—1,500 rpm.
If the fluid pressure is low, replace the oil pump
assembly.
Warning
If the valve is left closed for more than 15 sec-
onds, the fluid temperature will increase ex-
cessively and adversely affect the oil pump.

Rear 7,112—7,848 kPa
(72.5—80.0 kg/cm2, 1,031—1,138 psi)
To measure the fluid pressure generated at the
gear housing, first open the gauge valve complete-
ly, increase the engine speed to 1,000—1,500
rpm, and then turn the steering wheel fully to the
left and right.
Warning
If the steering wheel is kept in the fully turned
position for more than 15 seconds, the fluid
temperature will rise excessively.
