POWER STEERING
Description
PRINCIPLES OF POWER STEERING
Power steering is one type of hydraulic device for utilizing engine power to reduce steering effort.
Consequently, the engine is used to drive a pump to develop fluid pressure, and this pressure acts on a
piston within the power cylinder so that the piston assists the rack effort. The amount of this assistance
depends on the extent of pressure acting on the piston. Therefore, if more steering force is required, the
pressure must be raised. The variation in the fluid pressure is accomplished by a control valve which is
linked to the steering main shaft.
WHEN TURNING
When the steering main shaft is turned in either di-
rection, the control valve also moves, closing one of
the fluid passages. The other passage then opens
wider, causing a change in fluid flow volume and, at
the same time, pressure is created. Consequently, a
pressure difference occurs between both sides of the
piston and the piston moves in the direction of the
lower pressure so that the fluid in the cylinder is
forced back to the pump through the control valve.
NEUTRAL (STRAIGHT±AHEAD) POSITION
Fluid from the pump is sent to the control valve. If
the control valve is in the neutral position, all the fluid will flow
through the control valve into the relief port and back to the
pump. At this time, hardly any pressure is created and because
the
pressure on the cylinder piston is equal on both sides, the piston
will not move in either direction.
± STEERINGPower Steering (Description)SR±18

IDLE±UP DEVICE
The pump produces the maximum fluid pressure
when the steering wheel is turned fully to the
right or left and, at this time, there is a maximum
load on
the pump which causes a decrease in engine
idle rpm. To solve this problem, vehicles are
equipped with an idle±up device which acts to
raise the engine idle rpm whenever there is a
heavy load on
the pump. As with the rack and pinion type steering, preload
is very important. If the preload is not correct, it
could result in such trouble as steering wheel play
or shimmy or lack of durability, so always make
sure that it is correct.
On ER engines, when the piston of the air con-
trol valve is pushed by fluid pressure, the air
valve opens and the volume of air by±passing
the throttle valve is increased to regulate engine
rpm.
The idle±up device functions to raise engine idle
rpm when pump fluid pressure acts on the air
control valve, installed to the pump body or pres-
sure tube, to control the flow of air.(SV Series)

3. CHECK FOR FOAMING OR EMULSIFICATION
HINT: Foaming and emulsification indicate either the exis-
tence of air in the system or that the fluid level is too low.
4. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.
Fluid: ATF DEXRON II
HINT: Check that the fluid level is within the HOT LEVEL
of the tank. If the fluid is cold, check that it is within the
COLD LEVEL of the tank.
CHECK IDLE±UP
1. WARM UP ENGINE
2. TURN AIR CONDITIONER SWITCH OFF
3. CHECK IDLE±UP
(a) Fully turn the steering wheel.
(b) Check that the engine rpm decreases when the air
control valve hose is pinched.
(c) Check that the engine rpm increases when the air
control valve hose is released.
On±Vehicle Inspection
CHECK DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG±20 (95506±00020) or
Borroughs No.BT±33±73F
Drive belt tension:
New belt 125
+25 Ib
Used belt 80
+20 Ib
HINT:
wºNew beltº refers to a belt which has been less than 5
minutes on a running engine.
wºUsed beltº refers to a belt which has been used on a
running engine for 5 minutes or more.
wAfter installing the drive belt, check that it fits properly
in the ribbed grooves.
FLUID LEVEL CHECK
1. KEEP VEHICLE LEVEL
2. BOOST FLUID TEMPERATURE
With the engine idling at 1,000 rpm or less, turn the steer-
ing wheel from lock to lock several times to boost fluid tem-
perature.
Fluid temperature: 80
°C (176°F)

6. START ENGINE AND RUN IT AT 1,000 RPM
After 1 or 2 seconds, fluid will begin to discharge from the
return hose. Stop the engine immediately at this time.
NOTICE: Take care that some fluid remains left in the
reservoir tank.
7. REPEAT STEPS 5 AND 6 FOUR OR FIVE TIMES UNTIL
THERE IS NO MORE AIR IN FLUID
8. CONNECT RETURN HOSE TO RESERVOIR TANK

3. WITH ENGINE IDLING, TURN STEERING WHEEL

4. STOP ENGINE2. REMOVE FLUID RETURN HOSE FROM RESERVOIR
TANK AND DRAIN FLUID INTO CONTAINER
5. FILL RESERVOIR TANK WITH FRESH FLUID
Fluid type: ATF DEXRON II

3. CHECK THAT FLUID IN RESERVOIR IS NOT FOAMY
OR CLOUDY AND DOES NOT RISE OVER MAXIMUM
WHEN ENGINE IS STOPPED
Measure the fluid level with the engine running. Stop the
engine and measure the fluid level.
Maximum rise: 5 mm (0.20 in.)
If a problem is found, repeat steps 5 to 8 on page SR±23±
Repair the PS if the problem persists.
BLEEDING OF POWER STEERING
SYSTEM
1. CHECK FLUID LEVEL IN RESERVOIR TANK
Check the fluid level and add fluid if necessary.
Fluid: ATF DEXRON II
HINT: Check that the fluid level is within the HOT LEVEL
of the tank If the fluid is cold, check that it is within the
COLD LEVEL of the tank.
2. START ENGINE AND TURN STEERING WHEEL FROM
LOCK TO LOCK THREE OR FOUR TIMES
With the engine speed below 1,000 rpm, turn the steering
wheel to left or right full lock and keep it there for 2 ± 3
seconds, then turn the wheel to the reverse full lock and
keep it there for 2 3 seconds.
