Component Locations
Index
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRSsection (23) before performing repairs or service.
Note the following special precautions when the steering gearbox removal/installation,
. Before removing the steering gearbox, remove the driver's airbag assembly and steering wheel.
. After installing the steering gearbox, ch6ck the wheel alignmentand adjust if necessary.

Steering Pump
Construc'tion
The pump is a vane-type incorporating a flow control valve (with an integrated relief valve) and is driven by a POLY-V-belt
from the crank pulley. The pump features 10 vanes. Each vane performs two intake/discharge operations for every rota-tion of the rotor. This means that the hydraulic fluid pressure pulse becomes extremely small during discharge.
Operation
The belt-driven pulley rotates the rotor through the drive shaft. As the rotor rotates. the hydraulic pressure is applied tothe vane chamber of the rotor and the vanes will rotate while being pushed onto the inner circumference of the cam ring.The inner circumference of the cam ring has an extended portion with respect to the center of the shaft, so the rollersmove downward in the axial direction as the carrier rotates. As a result of this roller movement, the internal volume of thevane chamber will change. resulting in fluid intake and discharge.
START OF FLUID INTAK€:FLUID INTAKE:FLUIO MOVEMENT:FLUID DISCHARGE:
DISCHARGE PORT
The vanes are pushed onlothe inner circumference of thecam ring.
The volume of the vane cham-ber increases so that fluid issucked in.
The sucked in fluid movestoward the discharge port.As the vanes return to thetheir original position on theinner side, the volume of thevane chamber decreases sothe fluid is discharged fromthe discharge port-

Troubleshooting
General Troubleshooting
Check the following before you begin:
o Has the suspension been modified in a way that would affect steering?
. Are tire sizes and air pressure correct?
. lsthe steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adiusted?
. ls steering fluid reservoirtilled to proper level?
. ls the engine idle speed correct and steadyT

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.
