KIT-GASKET-MCH 2338683 - Caterpillar

Caterpillar has developed a maintenance management tool that evaluates oil degradation and detects the early signs of wear on internal engine 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 engine. The S O S analyst uses the results of elemental analysis 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 in order to determine if the oil has degraded. Tests are performed in order to look at the oxidation, nitration, and viscosity of the oil. The S O S analyst uses trend analysis and proprietary guidelines to determine if the oil has reached the end of useful life.Note: The standard oil analysis should include: Oxidation, Nitration, Viscosity, and wear metals at a minimum.Oil contamination tests are performed in order to determine if anything harmful has entered the oil. This analysis relies on the results from the following tests: elemental analysis, water, and glycol. The S O S Services program has guidelines that are used in order to evaluate the level of contamination in the engine oil.Oil identification is another important part of the S O S Oil Analysis program. The wrong oil in an engine can severely damage internal components. The wrong oil can also produce excessive deposits in the combustion chamber. Deposits in the combustion chamber may lead to valve failures, piston ring scuffing, and a loss of oil control. The S O S 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 engine, and to help you identify potential problems. A properly administered S O S Services Oil Analysis program helps prevent costly damage, reduces repair costs, and reduces downtime.Note: Obtain each oil sample when the oil is warm and mixed. The sample is ensured to be representative of the oil in the engine crankcase.Corrosive Gaseous Fuels
Corrosive gases may contain high levels of sulfur compounds, halide compounds, and ammonia compounds. Your Cat dealer has specific guidelines for these corrosive compounds. Consult your Cat dealer regarding the best methods for measuring and controlling these compounds in your gaseous fuel supply.When these corrosive compounds are present in gaseous fuels, perform additional tests on used gas engine oils. These additional tests may also be used if an oil related issue cannot be resolved through the standard set of S O S Services tests.Some gaseous fuels may contain significant amounts of corrosive compounds. These corrosive compounds can form highly corrosive acids in the engine oil. The S O S Services tests for Oxidation, Nitration, and Viscosity will indicate that these acids have degraded the oil. In many applications, these tests
