General Troubleshooting
Check the following before you begin:. Has the suspension been modified in a way that would affect steering?. Are tire sizes, tire variety and air pressure correct?. lsthe steering wheel original equipment or equivalent?. lsthe powersteering pump belt properlyadiusted?
. ls steeringfluid reservoirfilledto proper level?. ls the engine idle speed correct and steady?

Adjust the rac* guide (see page 17-3).
lf the problem is not corrected bY
adjusting the rack guide, replace
the gearbox.
Adiust the belt tension. Feplace the

Air in reservoir, or check Powersteering Iluid level.
lf ltuid level is OK, check O-rings
and seals on both ends of thepump inlet hose, and the P/Spump housing mating surfaces
and the pumP shaft oil seal for
suction leaks. RePlace Parts as
nocessary.

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,

. The master cylinder pushrod-to-piston clearancemust be checked and adjustments made, if neces_sary, before installing the master cylinder.. ABS type is shown, conventional brake type is similar.
1. Set the special tool on the master cylinde. body; push
in the center shaft until the top of it contacts the endofthe secondary piston by turning the adjusting nut.
Without disturbing the center shaft's Dosition, installthe specialtool upside down on the booster.Install the master cylinder nuts, and tighten to thespecified torque.
Connect the booster in-line with a vacuum gauge O _
101 kPa (0 - 760 mmHg, 30 in.Hg) to the booster,sengine vacuum supply, and maintain an enginespeed that will deliver 66 kpa (500 mmHg, 20 in.Hg)vacuum.
With a feeler gauge. measure the clearance Detweenthe gauge body and the adjusting nut as shown.

NOTE: lf the clearance between the gauge bodyand adjusting nut is 0.4 mm (0.02 in), the pushrod-to-piston clearance is 0 mm. However, if the clear_ance between the gauge body and adjusting nut is0 mm, the pushrod-to-piston clearance is 0.4 mm(0.02 in) or more. Therefore, it must be adjusted andrechecked.
6. lf clearance is incorrect, loosen the star locknut, andturn the adjuster in or out to adjust.
