inner sockets.
4.
Install the boot clamps to the boots, as shown.
CAUTION:
Do not reuse the large boot clamps.
5.
Crimp the large boot clamps, using Tool.
6.
Install the cylinder tubes to the gear housing assembly.
7.
Install the lock nuts and outer sockets to the inner sockets.
8.
Thread the outer sockets onto the inner sockets to the specified
length "L", then tighten the lock nuts to the specified torque.
Refer to

POWER STEERING OIL PUMP

On-Vehicle Inspection and Service
EGS0011M
CHECKING RELIEF OIL PRESSURE
CAUTION:
Before starting work, confirm that the belt tension is within specification. Refer to
1.
Connect the Tool between the power steering oil pump dis-
charge connector and the high pressure hose, then bleed the air
from the hydraulic circuit. Refer to
2.
Start the engine. Run the engine until the power steering fluid temperature in reservoir tank reaches 50 –
80
°
C (122 – 176
°
F).
CAUTION:
●
Warm up the engine with the shut-off valve fully opened. If the engine is started with the shut-off
valve closed, fluid pressure in the power steering oil pump increases to maximum pressure.
This will raise fluid temperature excessively.
●
Do not contact the belt with the hose while the engine is running.
3.
With the engine at idle, close the shut-off valve and read the relief oil pressure.
CAUTION:
Do not close the shut-off valve of the pressure gauge for more than 10 seconds.
4.
After measurement, open the shut-off valve slowly.
●
If relief oil pressure is outside the specification, replace the power steering oil pump. Refer to
5.
After inspection, disconnect the oil pressure gauge and oil pressure gauge adapter from the hydraulic cir-
cuit, then connect the power steering oil pump discharge connector. Add fluid and bleed the air from the
hydraulic circuit thoroughly. Refer to
PS-6, "Air Bleeding Hydraulic System"
.
