Checking Hydraulic SystemNJST0016Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to ªBleed-
ing Hydraulic Systemº, ST-8.
2. Run engine at idle speed or 1,000 rpm.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, fluid pressure in oil pump
increases to maximum. This will raise oil temperature abnor-
mally.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:
QG15, 18 engine
8,600 - 9,200 kPa (86.0 - 92.0 bar, 88.7 - 93.8
kg/cm
2, 1,247 - 1,334 psi)
YD22 engine
8,800 - 9,400 kPa (88.0 - 94.0 bar, 88.7 - 95.8
kg/cm
2, 1,261 - 1,362 psi)
+If pressure reaches maximum operating pressure, system is
OK.
+If pressure increases above maximum operating pressure,
check power steering pump flow control valve. Refer to ST-25.
4. If power steering pressure is below the maximum operating
pressure, slowly close shut-off valve and check pressure
again.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
+If pressure increases to maximum operating pressure, gear is
damaged. Refer to ªRemoval and Installationº, ST-16.
+If pressure remains below maximum operating pressure, pump
is damaged. Refer to ªDisassemblyº, ST-26.
5. After checking hydraulic system, remove Tool and add fluid as
necessary. Then completely bleed air out of system. Refer to
ST-8.
