ROTATOR A 0316416 - Caterpillar

Premature Engine Wear
Probable Causes
Incorrect engine oil
Contaminated engine oil
Contaminated inlet air
Contaminated fuel
Restriction in a passage for engine oilRecommended Repairs
Engine Oil
Use engine oil that is recommended and change the engine oil at the interval that is recommended by the engine's Operation and Maintenance Manual.To determine whether the engine oil is contaminated, obtain an analysis of the engine oil.Contaminated Inlet Air
Inspect the engine air cleaner for cleanliness and good condition. Inspect the connections and the gaskets for the air system.Contaminated Fuel
Inspect the fuel filter. Replace the fuel filter, if necessary.Contaminants in the fuel such as hydrogen sulfide, sulfur, and chlorofluorocarbons can lead to the formation of acids in the crankcase. Obtain a fuel analysis.Restriction in a Passage for Engine Oil
When some components of the engine show bearing wear in a short time, the cause can be a restriction in a passage for engine oil.An indicator for the engine oil pressure may indicate sufficient pressure, but a component is worn due to a lack of lubrication. In such a case, look at the passage for the engine oil supply to the component.
