Engine Lubrication System Maintenance Precautions

Publication Date: 2022-08-08

The primary function of the engine lubrication system is to prevent friction from occurring between parts that have relative motion.

 

Oil in the lubrication system cycle workflow - gear type oil pump from the oil sump to absorb oil, after the oil cooler and filter, respectively, flow to the left and right camshaft oil channel and the main oil channel, through the main oil channel to the turbocharger, crankshaft, piston, cooling nozzle and other parts of the oil supply. After completing its task, the oil naturally flows back to the oil sump by its own gravity and then starts the next cycle.

 

1. Oil level check

The oil level checked while the engine is stopped is more accurate. When checking, make sure that the engine is placed horizontally.

 

2. Oil filter change

Change the oil filter at every oil change or if the differential pressure of the oil filter reaches 103 kPa. Note: Do not attempt to clean the oil filter and then use it again.

 

3. Drain the oil

You need to drain the old oil before changing the oil. Be careful not to drain the oil when it is cold. Because waste particles settle to the bottom of the oil pan when the oil is cold, these waste particles may not be drained with the cold oil. Drain the oil in the sump after the engine has been running and the oil is still warm, as this will help to drain the waste particles suspended in the oil as well.

 

4. Disassemble and check the old filter element 

Cut off the end caps on both sides of the oil filter element. Unfold the pleated paper and check the filter element for metal debris. Excessive metal debris in the filter element may indicate early wear or an impending failure. Use a magnet to separate the ferrous and non-ferrous metals found in the oil filter element.

 

5. Refilling the oil

Remove the oil filler cap. Oil can only be added to the crankcase through the oil filler tube.

 

6. Crankcase breather 

The crankcase breather is a simple venting device installed above one of several valve covers and then connected to the atmosphere through a breather tube outside the generator room. The crankcase breather and breathing tube should be kept free of blockage and oil gathering.
