INPUT SHAFT
High assist at lower speedsl
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
diiference in angle created between the input shaft and the valve opens the tluid passage on one side, and closes the fluidpassage on the other side, at each pair of orifices. The fluid pressure lncreases in the side of the power cylinder fed by thelarger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through theinput shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example, when parking or making low speed turns), and the passages become smaller andpower assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ahead).

Pressure Control
Low assist at higher speedsl
When steering resistance is low, such as when driving at high speeds, or when driving straight ahead. the lnput shaft is
near or in the neutral position, so there is liftle or no flow to any of the power cylinder orifices. Most of the feed pressure
from the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cvlin-
der, resulting in low or no assist.

Inspection and Adjustment
Steering Operation
Place the front wheels in the straight ahead position and
measure the distance the steering wheel can be turned
without moving the front wheels.
ROTATIONAL PLAY: 0 - 10 mm {0 - 0.39 inl
lf the play exceeds the service limit. perform rack guide
adiustment (see page 17-211.
lf the play is still excessive after rack guide adjustment.
inspect the steering linkage and gearbox as described
on the neld page.
Power Assist Check with
Vehicle Parked
Check the power steering fluid level (see page 17-
21) and pump belt tension (see page 17-201.
Start the engine, allow it to idle. and turn the steer
ing wheel from lock-to-lock several times to warm
up the fluid.
Attach a spring scale to the steering wheel. With the
engine idling and the car on a clean. dry floor. pull
the scale as shown and read it as soon as the tires
begin to turn,
4. The scale should read no more than 34 N (3.5 kgf,
7.7 lbf). lf it reads more, check the gearbox and
pump.

Check the reservoir at regular intervals, and add fluid as
neceSsary.
CAUTION: Use only Genuine Honda Powel Ste€ring
Fluid-V. Using other fluids such as ATF or othor manu-
laclurer's power ste€ring fluid will damag€ the systom.

Raise the reservoir and disconnect the return hose
that goes to the oil cooler.
Connect a hose of suitable diameter to the discon-
nected return hose and put the hose end in a suit-
able container.
CAUTION: Take care not to spill thq fluid on lhe
body and parts. Wipe off any spilled fluid al onc€.
Start the engine. let it run at idle, and turn the steer-
ing wheel from lock-to-lock several times. When
fluid stops running out of the hose, shut off the
engine. Discard the fluid.

RETURN HOSE{From the oilcooler)
4. Reinstallthe return hose on the reservoir.
5. Fill the reservoir to the uDDer level line.
6. Start the engine and run it at fast idle, then turn the
steering from lock-to-lock several times to bleed air
from the system,
7. Recheck the fluid level and add some it necessary.
CAUTION: Do not lill the reservoir boyond thc
upper level line.

NOTE: Perform rack guide adjustment with the wheels
in the straight ahead position.
1. Loosen the rack guide screw locknut with the spe-
cialtool, then loosen the rack guide screw.
Tighten the rack guide screw until it compresses the
spring and seats against the rack guide, then loosen
it.
Retighten ihe rack guide screw to 3.9 N.m (0.4
kgf.m, 2.9 lbi.ft), then back it ofl to specified angle.
