Pressure gauge
CHECKING THE STEERING GEAR PETENTION HYDRAULIC
PRESSURE1. Disconnect the pressure hose from the oil
pbmd, and iheh
connect the special tools.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50~60OC (122~14pyF).
3. ‘Start the engine and idle it at 1,000 +
100 rem: .‘,’.
4.Fully close and fully open the shut-off valve of the pressure
gauge.
5.Turn the steering wheel all the way to the left or right; then
check whether or not the retention hydraulic pressure is the
standard value.
Standard value: 7.5-8.2 MPa (1,067-1,166 psi)6. When not within the standard value, overhaul the steering
gear box.
Remeasure fluid pressure.
7.Remove the special tools, and then tighten the pressure hoseto the specified torque.
8. Bleed the system.
OIL PRESSURE SWITCH CHECKNlSFUAB1. Disconnect the pressure hose from the oil pump, and then
connect the special tools.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. The engine should be idling.
4. Disconnect the connector for the oil pressure switch, and
place an ohmmeter ,in position.
5.Gradually close the shut-off valve of the pressure gauge andincrease the hydraulic pressure then check whether the
hydraulic pressure that activates the switch is the standard
value.
Standard value: 1.5-2.0 MPa (213-284 psi)
6. Gradually open the shut-off valve and reduce the hydraulic
pressure; then check whether the hydraulic pressure that
deactivates the switch is the standard value.
Standard value: 0.7-1.2 MPa (100-171 psi)
7.Remove the special tools, and then tighten the pressure hoseto the specified torque.
8. Bleed the system.

Caution
1.Be sure to tie the cord of the special tool to the nearby
part.2. Loosen the nut but do not remove it.
11. REMOVAL OF FRONT EXHAUST PIPE
Refer to GROUP
2-Stabilizer Bar.
12. REMOVAL OF GEAR BOX ASSEMBLY
(I 1 Move the rack completely to the right and then remove
the gear box from the
crossmember.
(2) While tilting the gear box downward, remove it to the
left.
Caution
When removing the gear box, pull it out carefully andslowly to avoid damaging the boots.
INSPECTION
NlSPCADaGEAR BOX FOR TOTAL PINION TORQUE
Using the special tools, rotate the pinion gear at the rate of one
rotation in approximately 4 to 6 seconds to check the total pinion
torque.Standard value:
0.6-l .3 Nm (5-l 1 in.lbs.1
NOTE
Measure the pinion torque through the whole stroke of the rack.If the measured value is not within the standard range, first
adjust the rack support cover, and then check the total pinion
torque again.If the total pinion torque cannot be adjusted to within the
standard range by adjusting the rack support cover, check the
rack support cover, rack support spring, rack support and
replace any parts necessary.CHECK THE TIE ROD FOR SWING RESISTANCE
(1) Give 10 hard swings to the tie rod.I
(2) Measure the tie rod swing resistance with a spring balance.
’Standard value: 8-20 N (1.8-4.4 Ibs.)
12-5 Nm (17-43 in.lbs.)l
(3) If the measured value exceeds the standard value, replace
tie rod assembly.
NOTE
Even if the measured value is below the standard value, thetie rod which swings smoothly without excessive play may
be used.SERVICE POINTS OF INSTALLATION
