3. Inspecting the engine oil pressure
Cause:
To confirm whether the bearing or lubricating system component is worn.
Equipment:
Pressure indicator assembly
Hose assembly
Temperature indicator
Connection:
1. Dismantle the engine oil pressure sensor
Note: The thread is taper pipe thread 1/8, and it is
required that the pressure range is (0
—
700)kPa ((0
—
6.9) bar or (0
—
100) psi) for special fittings and
hose connections.
2. Connect the pressure indicator assembly and hose
assembly
Important notice : if the pressure reading is low-
er than 72 kPa (0.72 bar or 10.5 psi), the engine
flames out.
3. Install the temperature indicator at the engine oil
filter element.
Note: When the engine and oil pressure indicator
are operated in an endurable extreme conditions, the
reading of the oil pressure indicator is up to 582kPa
(5.82 bar or 85 psi). This does not result in damage
to the engine.
4. Enable the engine to be operated for about 5
minutes, so that the engine oil temperature reaches
the specified value; after that, measure the engine
oil pressure.
