Lubrication circuit
Oil pressure check
After the assembly operation, fill the engine with oil and fuel;
connect a 10 bars pressure gauge to the fitting on the oil filter.
Start the engine and check the pressure reaction according to oil
temperature.
Oil pressure curve with the engine at its maximum speed
65
- 32 -
It is shown on the filter and obtained with the engine at 3000
rpm at N power; the pressure is expressed in bars and the
temperature in degrees Celsius. The curve represents the
pressure minimum value, while its maximum value is 5 bars. The
minimum oil pressure (1200 rpm) with the oil temperature at
100° C shall not be lower than 0.8 bars.
Note: When the engine has been run in, the oil lubrication
maximum temperature shall be lower than the following
addition: ambient temperature + 95° C.
