IGNITER
Inspection
1. Disconnect the igniter connector.
2. Connect the
SST between the igniter and the wire harness.
3. Connect the connector (4-pin) of the Igniter Checker to the
adapter harness.
4. Connect the power leads of the
SST (Igniter Checker) to
the battery.
Spark test
1. Turn the ignition switch ON.
2. Disconnect the high-tension coil lead from the distributor
and hold it
5--10mm (0.20-0.39in) from a ground.
Caution
l Hold the SW2 ON for no longer than one second.
3. Flip the SW2 ON and OFF, and verify that strong blue sparks
are discharged from the high-tension lead.
Voltage test
1. Turn the ignition switch ON.
2. Connect a voltmeter to the terminal of the black wire of the
adapter harness.
Caution
l Hold the SW2 ON for no longer than one second.
3. Flip the SW2 ON and OFF, and verify that the voltmeter

Field coil
1. Check for continuity between the M terminal wire and brush-
es with an ohmmeter. Replace the yoke assembly if there
is no continuity.
2. Check continuity between the M terminal wire and yoke with
an ohmmeter. Replace the yoke assembly if there is con-
tinuity.
3. Check if the field coil is loose. Replace the yoke assembly
if necessary.
Armature
1. Check continuity between the commutator and the core with
an ohmmeter. Replace the armature it there is continuity.
2. Check continuity between the commutator and the shaft with
an ohmmeter. Replace the armature if there is continuity.

AIR BLEEDING
Caution
l Do not start the engine.
l Jack up the front of the vehicle.
1. Check the fluid level. (Refer to page N-27.)
2. Turn the steering wheel fully to the left and right several times
with the engine not running.
3. Recheck the fluid level. If the level has lowered, add fluid.
4. Repeat steps 2 and 3 until the fluid level stabilizes.
5. Start the engine and let it idle.
6. Turn the steering wheel fully to the left and right several
times.
7. Check that the fluid is not foamy and that the fluid level has
not dropped.
8. Add fluid if necessary and repeat steps 6 and 7.
STEERING WHEEL AND COLUMN
Inspection (On-vehicle)
Steering wheel effort
1. With the vehicle on a hard, level surface, put the wheels
in the straight-ahead position.
2. Start the engine and warm the power steering fluid to
50-60°C
(122-14OOF) by turning the steering: wheel fully
left and right several times.
3. With the engine running at idle speed, attach a pull scale
to the outermost point of the steering wheel spoke. Then,
starting with the wheels in the straight-ahead position, check
the steering effort required to turn the steering wheel to the
left and to the right.
4. If the measured effort exceeds specification, check the fol-
lowing: fluid level, air in system, fluid leakage at hose or con-
nections, function of P/S oil pump and gearbox, and tire
pressures.
Steering wheel effort: 29 N (3.0 kg, 6.6 lb) or less 03UONX-033

Oil seal and bearing
1. Use the SST to remove the bearing and the oil seal from
the plug.
Caution
l The oil seal can not be reused.

1. Use the SST to remove the outer box.
Oil seal and inner guide
1, Use the SST to remove the oil seal and inner guide toward
the cylinder side.
Caution
l The oil seal can not be reused.
lnspectlon
Steerlng rack
1. Check the rack for cracking or other damage or for abnor-
mal wear of the teeth; replace it if necessary.
2. Check the seal ring installation part of the rack for abnor-
mal wear or damage; replace it if necessary.
3. Use V blocks to support both ends of the large-diameter
part of the rack; check for excessive bending; replace it if
necessary.
Bending limit: 0.15mm (0.006 In) (near rack center)
Plug
1. Check for scratches or other damage at the oil seal instal-
lation inner diameter; replace it if necessary.

Assembly
1. Mounting bracket and mounting rubber (gear housing
side)
(1) install the mounting bracket and mounting rubber (gear
housing side) to the gear box. ,
2. Steering rack
(1) Install a new O-ring and new seal ring to the rack’s
piston.
(2) After installing the seal ring, seat it properly at the pis-
ton circumference.
(3) Install the oil seal and inner guide to the
SST.
(4) Using the SST, place the oil seal and inner guide at the
edge of the steering rack’s pinion.
(5) After mounting the steering rack to the gear box, use
a press to install the oil seal and inner guide to the cor-
rect position.
Caution
l When pressing in, do not apply a load pressure of
more than 29,430 kPa (300 kg/cm2, 4,266 psi), be-
cause to do so will damage the oil seal and inner
guide.
l Apply grease to the seal ring, O-ring oil seal and in-
ner guide.
23UONX-056
3. Outer box assembly
(1) Install a new U-gasket and O-ring to the outer box.
(2) After installing the SST to the rack, install the outer box,
and use the
SST to tighten.
Tightening torque:
39-49 N-m (4-S m-kg, 29-36 ft-lb)
4. Cylinder air-tightness check
(1) Install the SST to the cylinder part of the gear housing.
(2) Using a vacuum pump, apply a vacuum of 400 mmHg
and check to be sure that the vacuum is maintained for
30 seconds.
(3) If there is any leakage, replace the oil seal.
5. Oil seal
(1) Use the SST to install a new oil seal to the gear housing.
Note
l Apply grease to the oil seal.

Disassembly note
Oil pump
Note
l As shown in the figure, when securing the oil pump
in a vise, be sure to use the SST so that force is not
applied to the pulley or shaft.
Assembly note
Rotor
1. Install the rotor to the shaft with the rotor’s identification mark
facing upward.
Cam ring
1. Install the cam ring so that its identification mark is facing
downward.
Vane
1. Install the vanes (10 pieces) to the rotor, with the R part of
the vanes facing outward.
Inspection
Note
l Replace the pump assembly if necessary.
Pump body
1. Check the front and rear pump bodies for cracking or oth-
er damage and for abnormal wear of the moving surface
of the rotor.
