PRECAUTIONS AND PREPARATION
Special Service Tools (Cont'd)
ST-2

Checking and Adjusting Drive Belts
Refer to MA section (``Checking Drive Belts'', ``ENGINE MAINTE-
NANCE'').
Checking Fluid Level
Check ¯uid level.
Use the correct range of the dipstick depending on the ¯uid tem-
perature. Use the ``HOT'' range at 50 to 80ÉC (122 to 176ÉF), or the
``COLD'' range at 0 to 30ÉC (32 to 86ÉF).
CAUTION:
+Do not over®ll.
+Recommended ¯uid is Automatic Transmission Fluid type
DEXRON
TMIII or equivalent.
Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, cha®ng and deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of ¯uid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ``lock'' position for ®ve seconds and
carefully check for ¯uid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If ¯uid leakage at connectors is noticed, loosen ¯are nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.

Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add ¯uid into oil tank to speci®ed level. Then, quickly turn steer-
ing wheel fully to right and left and lightly touch steering stop-
pers.
Repeat steering wheel operation until ¯uid level no longer
decreases.
3. Start engine.
Repeat step 2 above.
+Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Air bubbles in reservoir tank
b. Clicking noise in oil pump
c. Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning steering wheel
slowly. This does not affect performance or durability of the system.
Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering ¯uid up to adequate operating tempera-
ture. [Make sure temperature of ¯uid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be in¯ated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from the neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to ``Bleed-
ing Hydraulic System'', ST-6.
2. Run engine at idle speed or 1,000 rpm.
Make sure ¯uid temperature 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, ¯uid pressure in the power
steering pump increases to maximum. This will raise ¯uid tem-
perature abnormally.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Power steering pump maximum operating pressure:
8,140 - 8,728 kPa (81.4 - 87.3 bar, 83 - 89 kg/cm
2,
1,180 - 1,266 psi)
+If pressure reaches maximum operating pressure, system is
OK.
+If pressure increases above maximum operating pressure,
check power steering pump ¯ow control valve. Refer to ST-16.

Removal and Installation
Before removal, clean gear housing and oil pump exteriors
using a steam cleaner. Then dry with compressed air.
+Plug openings of gear housing, and securely locate hose con-
nectors at a position higher than oil pump and cover with paper
towels.
+Be extremely careful to prevent entry of foreign matter into
hoses through connectors.
+When installing pitman arm, align four grooves of pitman arm
serrations with four projections of sector shaft serrations, and
install and tighten lock washer and nut.
Inspection
Do not disassemble for power steering gear assembly.
TURNING TORQUE MEASUREMENT
1. Measure turning torque at 360É position.
a. Install steering gear on Tool.
