CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer toPS-6, "
Air
Bleeding Hydraulic System".
2. Start engine. Run engine until oil temperature reaches 50 to
80°C(122to176°F).
CAUTION:
lLeave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
lBe sure to keep hose clear or belts and other parts when
engineisstarted.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump is the
relief oil pressure is outside the standard. Refer toPS-26, "
Dis-
assembly and Assembly".
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer toPS-6, "
Air Bleeding Hydraulic System".
Removal and InstallationEGS001LM
REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove radiator shroud. Refer toCO-11, "
Components".
3. Loosen drive belt. Refer toEM-12, "
DRIVE BELTS".
4. Remove drive belt from oil pump pulley.
5. Disconnect the pressure sensor electrical connector.
6. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer toPS-30,
"HYDRAULIC LINE".
7. Remove oil pump mounting bolts, and then remove power steering pump. Refer toPS-30, "
HYDRAULIC
LINE". Relief oil pressure:
8,500 - 9,300 kpa (86.7 - 94.9 kg/cm
2, 1,233 - 1,349 psi)
