Troubleshooting
Fluid Leaks
Check the gearbox assembly for oil leaks carefully. Oil can leak out of various points. depending on location of thefaulty 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 tromthe pinion shaft.
Replace the cylinder end seal onthe gear housing side.
Leaking lrom cylinder end intoright tie-rod boot.Replace the cylinder end seal onthe cylinder end side.
Leaking lrom the shaft upper endsectron or pin engagement sec,tion ol the pinion shaft.Replace the valve body unit.

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.

LEVEL LINE
LOWER LEVEL LINE
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
upper l€vel line.
