Checking Hydraulic System
Before starting, check belt tension, driving pulley and tire
pressure.
1. Set Tool. Open shut-off valve. Then bleed air. (See "Bleed-
ing Hydraulic System".)
2. Run engine.
Make sure temperature of fluid in tank rises to 100°C (212OF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, oil pressure in oil pump will
increase to relief pressure, resulting in an abnormal rise in oil
temperature.
3. Check pressure with steering wheel fully turned to left and
right positions 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:
6,669
-
7,257 kPa
(66.7
-
72.6 bar, 68
-
74 kg/cm2, 967
-
1,052 psi)
at idling
4. If oil pressure is below the standard pressure, slowly close
shut-off valve and check pressure.
When pressure reaches the standard pressure, gear is
damaged.
When pressure remains below the standard pressure, pump
is damaged.
5. If oil pressure is higher than the standard pressure, pump is
damaged.
Do not close shut-off valve for more than fifteen seconds.
6. After checking hydraulic system, remove Tool and add fluid
as necessary, then completely bleed air out of system.
