Cat has developed a maintenance management tool that evaluates oil degradation and detects the early signs of wear on internal components. The Cat tool for oil analysis is called S O S oil analysis and the tool is part of the S O S Services program. S O S oil analysis divides oil analysis into four categories:
Component wear rate
Oil condition
Oil contamination
Oil identificationComponent Wear Rate analysis evaluates the wear that is taking place inside the lubricated compartment. The S O S Services analyst uses the results of elemental analysis and particle count tests to evaluate the wear. Trend analysis and proprietary wear tables are then used to determine if wear rates are normal or abnormal.Oil Condition analysis is used to determine if the oil has degraded. Tests are done to look at the oxidation, sulfation, and viscosity of the oil. The S O S Services analyst uses established guidelines or trend analysis to determine if the oil has reached the useful life limit.Oil Contamination tests are performed to determine if anything harmful has entered the oil. This analysis relies on the results from the following tests: elemental analysis, soot, particle count, fuel dilution, water, and glycol. The S O S Services program has guidelines for the level of contamination that are allowed in Cat engines.Oil Identification is another important part of the S O S oil analysis program. The wrong oil in an engine can severely damage major components. The S O S Services analyst uses elemental analysis and viscosity results to identify key characteristics of the oils.These four types of analysis are used to monitor the condition of your equipment, and to help you identify potential problems.
