NR Series LUBRICATION  LUBRICATION SYSTEM  ON-VEHICLE INSPECTION  


PROCEDURE

Hide 1.CHECK ENGINE OIL LEVEL

a.

Warm up and stop the engine, then wait for 5 minutes.


b.

Check that the engine oil level is between the low level and full level marks on the engine oil level dipstick.

If the level is low, check for engine oil leaks and add engine oil to the full level mark.

NOTICE:

Do not fill to above the full level mark.



Hide 2.CHECK ENGINE OIL QUALITY

a.

Check the engine oil for deterioration, water intrusion, discoloration or thinning.

If the quality is visibly poor, replace the engine oil and oil filter sub-assembly.


Hide 3.INSPECT OIL PRESSURE

Install an oil pressure gauge with the adapter.


d.

Warm up the engine.

HINT:

After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).



e.

Check the oil pressure.

Standard Oil Pressure:
Condition Specified Condition
Idling 60 kPa (0.6 kgf/cm2, 9 psi) or higher
2000 rpm 150 kPa (1.5 kgf/cm2, 22 psi) or higher


If the result is not as specified, check the quality of the engine oil and check the oil paths for clogging. Repair or replace if necessary. If the engine oil pressure is still not as specified, check the oil pump assembly.
