Troubleshooting
Fluid Leaks
Check the gearbox assembly for oil leaks carefully. Oil can leak out ot various points, depending on location of the faulty
oil seals/seal rings. Check the following before removing the gearbox from the frame.
Steering GearboxLeaking from the oil seal on thetop of the valve housing.Replace the valve oil seal fromthe valve housing.
Leaking from cylinder end intoleft tie rod boot.Replace the valve oil seal fromthe pinion shaft.
Replace the cylinder end seal onthe valve body unit side.
Leaking from cylinder end intoright tie-rod boot.Replace the cylinder end seal onthe cylinder end side.
Leaking lrom the shaft upper endsection or pin engagement sec-tion of the pinion shaft.Replace the valve body unit.
Tighten the connector. It it's stillleaking, replace the line, cylinderor valve housing.
Leaking from cylinder line A or Bconnections (at tlare nut).
Leaking caused by a damagedcylinder line A or B.Replace cylinder line A or B.
Leaking from pump outlet hoseand return line joint fitting on thevalve body unit {at tlare nut}.

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 limit, perform rack guide adjust-
ment (see page 17-15).
lf the play is still excessive after rack guide adjustment,
inspect the steering linkage and gearbox as described
on the next page.

Power Assist Check with
Vehicle Parked
1. Check the power steering fluid level (see page 17-
15) and pump belt tension (see page 17-14).
2. Start the engine, allow it to idle, and turn the steer-
ing wheel from lock-toiock several times to warm
up the fluid.
3. Aftach a spring scale to the steering wheel, With the
engine idling and the vehicle on a clean. dry floor,
pull the scale as shown and read it as soon as the
tires begin to turn.
SPRINGSCALE(Commercially
available)
The scale should read no more than 29 N (3.0 kgf,
6.6 lbfl. lf it reads more, check the gearbox and
oumo.

Inspection and Adjustment
Pump Belt
When using a new belt. first adjust the deflection or ten-
sion to the values for the new belt, then readjust the
deflection or tension to the values for the used belt after
running engine for five minutes.
Inspection
Note these items during inspection:
a lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions lor the tension
gauge.
'1. Remove the P/S reservoir from the bracket, and set
it aside.
2. Attach the belt tension gauge to the belt with the
gauge face toward the engine, and measure the ten-
sion of the belt.
Remove the belt tension gauge carefully to avoid
hitting the gauge reset lever.
Tension:
Used Belt: 390 - 540 N {40 - 55 kgf, 88 - 121 lbf)
New Belt: 7,[0 - 840 N (75 - 90 kgf, 165 - 198 lbf)

Measurement without Belt Tension Gauge:
Apply a force ot 98 N (10 kgf,22 lbt) and measure the
deflection between the power steering pump and the
crankshaft oullevs.

Adjust the belt tension by moving the power steer-
ing pump with a 1/2" drive breaker bar to obtain theproper belt tension, then retighten the mounting

Fluid Replacement
Check the reseryoir at regular intervals, and add the rec-
ommended fluid as necessary.
CAUTION: Always use Gsnuine Honda Power Steering
Fluid-V or S. Using any other type of power steering
tluid or automatic transmission fluid can cause increassd
wear and poor steering in cold w3athel.

1.Raise the reservoir. then disconnect the return hose
to drain the reservoir. Take care not to spill the fluid
on the body and parts. Wipe off any spilled fluid at
once.
2, Connect a hose of suitable diameter to the discon-
nected return hose, and put the hose end in a suit-
able container.
3. Stan 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.
4. Beinstallthe return hose on the reservoar.
5. Fill the reservoir to the upper 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 if necessary.
Do not fill the reservoir beyond the upper level line.

Check the fluid pressure as follows to determine whetherthe trouble is in the pump orgearbox.
1. Check the powsr steering fluid level (see page 17-15), and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump

8. Turn the steering wheel from lock-to-lock severaltimes to warm the fluid to operating temperature.
9, Measure steady-state fluid pressure while the engineis idling. lf the pump is in good condition, the gauge
should read less than 1,500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet hose or valve bodvunit (see General Troubleshooting).
10. Close the pressure control valve, then close theshut-off valve gradually until the pressure gauge
nsedle is stable. Read the pressure.

Pump Pressure Check With T/N 07406 -
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering tluid level (see page 17-
151, and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump

Steering Wheel
Removal
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
1. Align the front wheels straight ahead. then remove
the driver's airbag assembly (see section 24) from
the steering wheel.
2. Disconnect the horn connector and cruise control
switch connectors.
CONTROLSWITCHES CONNECTOR
3. Loosen the steering wheel bolt, then install a steering
wheel puller on the steering wheel and remove it.
Note these items when removing the steering wheel:
. Do not tap on the steering wheel or the steering
column shaft when removing the steering wheel.
. lf you thread the puller bolts into the wheel hub
more than five threads, the bolts will hit the cable
reel and damage it. To prevent this, install a pair
of jam nuts five threads up on each puller bolt.
