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.
ROTATIONAL PLAY

Inspection and Adjustment
Pump Belt
NOTE: When using a new belt, first adjust the deflection
or tension 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
Attach the soecial tool to the belt and measure the ten-
sion of the belt.
Tension:
Usad Belt: 390 - 54O N {/10 - 55 kgf. 88 - 120 lbf}
Nsw Belt: 740 - 880 N {75 - 90 kgf. 170-2(X)lbf)
NOTE:
. lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions for the tension
gauge.

Adiustment
1. Loosen the power steering pump mounting bolts.
2. Turn the adjusting bolt to get the proper belt ten-
sion, then retighten the bolts.
3. Stan the engine and turn the steering wheel from
lock-to-lock several times. then stop the engine and
recheck the deflection of the belt.

Inspection and Adjustment
Pump Pressure Check
Check the fluid Dressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE; First check the power steering fluid level and
pump belt tension.
CAUTION: Disconnect the pump outlet hose (high-pres-
sure line) with care so as not to spill the power steering
fluid on the frame and other parts,
1. Disconnect the pump outlet hose (high-pressure)
from the pump outlet fitting, then install the P/S
joint adapter (pump) on the pump outlet.

PUMPFITTING
Connect the P/S joint adapter (hose) to the power
steering pressure gauge, then connect the pump
outlet hose (high-pressure)to the adapter.
Install the power steering pressure gauge to the P/S
joint adapter (pump).
Open the shut-off valve fully.
Open the pressure control valve fulli.
1.
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. lf
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgflcm',213 psi).
lf it reads high, check the outlet hose or valve body
unit (see General Troubleshooting 17-101.
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable, Read the pressure.
lmmediately open the pressure control valve fully.
CAUTION: Do not keep the pressure control valve
closed more then 5 seconds or the pump could be
damaged by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm',924- 1,067 psi). A low.eading means pump output is
too low for full assist. Repair or replace the pump.

Power Steering Hoses, Lines
Replacement
NOTE:
. Connect each hose to the corresponding line securely
until it contacts the stop on the line. Install the clamp
or adjustable clamp at the specified distance from the
hose end as shown.
. Add the recommended power steering fluid to the
specified level on the reservoir and check for leaks.
ADJUSTABLE HOSE CLAMP: (al
. Position the adjustable hose clamps at the points
indicated by (a) in the drawing below.
. Slide the hose over the line until it contacts the stop.
CAUTION: Ch€ck all clamps for deterioration or defor-
mation; replace the clamps with new ones it necessary'

5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgf/cm', 14.2 psi), replace the pump as an
assembly.
f. AIR PRESSURE
lf the flow control valve tests OK, reinstall it in the
pump. lf the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
