Checking Neutral Position on Steering Wheel
lMake sure that wheel alignment is correct.
Wheel alignment:
Refer to FA section (``Inspection and Adjustment'',
``SERVICE DATA AND SPECIFICATIONS'').
lVerify that the steering gear is centered before removing the
steering wheel.
Checking
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel
and reinstall it correctly.
3. If the neutral position is still not correct:
a. Loosen tie-rod lock nuts.
b. Move tie-rods, in opposite direction, the same amount on
both left and right sides.
This will compensate for error in the neutral position.
Checking Front Wheel Turning Angle
1. Rotate steering wheel fully right, then left; measure turning
angle.
Turning angle of full turns:
Refer to FA section (``Inspection and Adjustment'',
``SERVICE DATA AND SPECIFICATIONS'').
2. If it is not within specification, check stopper bolt adjustment.
Refer to FA section (``FRONT WHEEL TURNING ANGLE'',
``Front Wheel Alignment'').
Checking Hydraulic System (For power
steering)
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to
``Bleeding Hydraulic System'', ST-5.
2. Run engine at idle speed or 1,000 rpm.
lMake sure temperature of fluid in reservoir tank rises to
60 to 80ÉC (140 to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine
is started with shut-off valve closed, fluid pressure in power
steering pump increases to maximum. This will raise fluid
temperature abnormally.
3. Check pressure with steering wheel fully turned to left and
right positions while idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel at full lock position for more
than 15 seconds.
Oil pump maximum pressure:
7,649 - 8,238 kPa (76.5 - 82.4 bar, 78 - 84 kg/cm
2,
1,109 - 1,194 psi) at idling
