V-BELT TENSION CHECKNlSFliAl
1.Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE, If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage,
of the
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.

STEERING - Service -Adjustment Procedures < Power Steering >IgJf~
4.Disconnect the high-tension cable, and then while operating
the starting motor intermittently, turn the steering wheel all;
the way to the left and right several times to drain all of the
fluid.
Caution, 35
Be careful not to position thq high-tension able ye&r the
carburetor or the delivery pipe.5. Connect the return hoses securely, and then
secur& it ,with
the clip.6. Fill the oil reservoir with the specified fluid up
td the Ibwerposition of the filter, and then bleed the air.

BLEEDINGNlSFKAG
1.Jack up the front wheels and support them by using a floor
stand.2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and right
several times.
4.Disconnect the high-tension cable, and then, while operatingthe starting motor intermittently, turn the steering wheel all
the way to the left and right several times
(for 1-5 to 20
seconds).
Caution
1. During air bleeding, replenish the fluid supply so thatthe level never falls below the lower positiin
@f the
eiter.I .“:
2. If air bleeding is done while engine is runnind, ‘the air
will be
brokeir up and absorbed intti the fluid;‘?ti’ sureto do the bleeding only while cranking.
5.Connect the ignition cable, and then start the engine (idling).6. Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is
upito the specified position on the level gauge.
8.Confirm that there is very little change in the fluid level whenthe steering wheel is turned left and right.
9.Check whether or not the change in the fluid level is within5 mm
(.2 in.) when the engine is stopped and when it is
running.
Caution
1.If the change of the fluid level is 5 mm I.2 in.) or more,
the air has not been completely bled from the system,
and thus must be bled completely.2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be abnormal
noises from the pump and the flow-control valve, and
this
condition could cause a lessening of the life of the
pump, etc.

OIL PUMP PRESSURE TESTNl9FlAF
CHECKING THE OIL PUMP RELIEF PRESSURE1. Disconnect the pressure hose from the oil pump, and then
connect the special tools.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
f 100 rpm.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it is
within the standard value range.
Standard value: 7.5-8.2
MPa (1,067-1,166 psi)
Caution
Pressure gauge shut off valve must not remain closed formore than 10 seconds.
5.If it is not within the standard value, overhaul the oil pump.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.
CHECKING THE PRESSURE UNDER NO-LOAD CONDITIONS1. Disconnect the pressure hose from the oil pump, and then
connect the special tool.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
-t 100 rpm.
4.
Check whether or not the hydraulic pressure is the standard
value when no-load conditions are created by fully openingthe shut-off valve of the pressure gauge.
Standard value:
0.8-I .O MPa (114-142 psi)
Limit: 1.5
MPa (213 psi)
5. If it is not within the standard value, the probable cause is
a malfunction of the oil line or steering gear box, so check
these parts and repair as necessary.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.
