Engine lubrication system maintenance precautions

The primary function of the engine lubrication system is to prevent friction between relatively moving parts.

The circulation workflow of engine oil in the lubrication system - the gear-type oil pump sucks the engine oil from the oil pan, and after passing through the oil cooler and filter, it flows to the left and right camshaft oil passages and the main oil passage respectively. The channels supply oil to the turbocharger, crankshaft, piston, cooling nozzle and other parts respectively. After completing its task, the engine oil will naturally flow back to the oil pan by its own gravity, and then start the next cycle.

Engine oil grade

Cat recognizes the American Petroleum Institute API's engine oil licensing and certification system. When there are multiple API levels to choose from, the one with the higher level should be used.

Cat DEO

Cat engine oils exceed many performance requirements of other diesel engine manufacturers. Therefore, this oil is an excellent choice for engines.

Engine oil level check

The oil level checked when the engine is stopped is more accurate. When checking, make sure the engine is level.

Replace the oil filter element

Replace the oil filter every time you change the oil, or when the oil filter pressure difference reaches 103 kPa. Note: Do not attempt to clean the oil filter before using it again.

Drain oil

The old oil needs to be drained out before changing the oil. Be careful not to drain the engine oil when the engine is cold. Because waste particles settle at the bottom of the oil pan when the oil is cold, these waste particles may not be drained out with the cold oil. After the engine is running, while the oil is still warm, drain the oil in the oil pan. This will help drain away the waste particles suspended in the oil

Disassemble and inspect the old filter element

Cut off the end caps on both sides of the oil filter element. Unfold the pleated paper and inspect the filter element for metal debris. Excessive metal debris in the filter element may indicate early wear or impending failure. Magnets are used to separate the ferrous and non-ferrous metals found inside the oil filter element.

Fill up engine oil

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

crankcase breather

The crankcase breather is a simple ventilation device installed above certain valve chamber covers, and then connected to the outside of the generator room through a breathing tube and connected to the atmosphere. The crankcase breather and breathing tube should be kept free of blockage and oil accumulation.
