IRack Guide Adjustment
NOTE: Perform rack guide adjustment with the wheels
in the straight ahead Position.
1. Loosen the rack guide screw locknut with the
cialtool.
'96 - '97 models:
Loosen the rack guide screw
'98 - '00 models:
Remove the rack guide screw and remove the old
sealant off of the threaded section.
Apply new sealant all around the threads. Loosely
installthe rack guide screw
Tighten the rack guide screw to 25 N'm (2.5 kgf'm.
18 lbf.ft), then loosen it.
Retighten the rack guide screw to 3 9 N'm (0.4 kgim,
2.9 lbf.ft), then back it off to specified angle.
Specified Return Angle: 20" max.
Tighten the locknut while holding the rack guide
screw.
Check for tight or loose steering through the com-
plete turning travel.
Perform following insPections:
. Steering operation (see page 17-30).
. Power assist with vehicle parked.

Fluid Replacement
Check the reservoir at regular intervals, and add fluid as
necessary.
CAUTION: Always us€ Genuine Honda Power Stearing
Fluid-V or S. Using any other type of power sto€ring
tluid or automatic transmission lluid can cause
increased wear and poor steering in cold weathor.

1. Raise the reservoir, then disconnect the return nose.
2. 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 tho fluid on the
body and parts. Wipe off any spill€d fluid at oncs'
3. 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.
4. Reinstall the return hose on the reservoir'
5. Fill the reservoir to the upper level line.
6. Start the engine and run it at fast idle, then turn the
steering trom lock-to-lock several times to bleed air
trom the system.
7. Recheck the fluid level and add some it necessary.
CAUTION: Do not fill the reservoir beYond the

lnspection and Adjustment
Pump Pressure Check
Check the fluid pressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE: First check the power steering fluid level andpump belt tension.
CAUTION: Disconnect the high pr$sure hos€ with care
so as not lo spill the power sieering tluid on tha frame
and other parts.
1. Disconnect the outlet line from the Dumo outlet fit-
ting, then installthe P/S joint adaptor (pump) on the
Dumo outlet.
2. Connect the P/S joint adaptor (hose) to the power
steering pressure gauge, then connect the outlet
hose to the adaptor.
3. Install the power steering pressure gauge to the P/Sjoint adaptor (pump) as shown.

7.
Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling. If
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet line or valve body
unit (see General Troubleshooting 17-22).
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable. Read the oressure.
lmmediately open the pressure control valve fully.
GAUTION: Do not keep lhe prossure control valve
clos€d more then 5 soconds or the pump could be
damagod by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm,, 920 -
1,070 psi). A low reading means pump output is too
low for full assist. Repair or replace the pump,
