Inspection
RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the Tool between oil pump discharge connector and
high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-8, "Inspection".
2. Start engine. Run engine until oil temperature reaches 50° to
80°C (122° to 176°F).
CAUTION:
• Leave 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.
• Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the Tool 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. Replace oil pump is the relief oil
pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraulic circuit, then add fluid
and bleed air. Refer to ST-8,
"Inspection".
