Caterpillar Scheduled Oil Sampling (S O S) Program is a series of diagnostic tests designed to identify and measure contamination and condition of oil in an engine's crankcase. S O S is also used to determine oil performance and component wear rates and is the best indicator for determining what is happening inside your engine.Caterpillar recommends using Scheduled Oil Sampling (S O S), at regularly scheduled intervals, to compliment a good preventive maintenance program.The Caterpillar Scheduled Oil Sampling Program, (S O S), was developed to help Caterpillar users realize the highest possible value from their equipment by minimizing repair costs and maximizing availability. The S O S program is a series of diagnostic tests which analyze used lubricating oils from the oil wetted compartments of the equipment. By analyzing the used oils, problems may be identified early, before extensive component failure occurs. This reduces repair cost and down-time.The S O S program is coupled with a wide range of repair options so that when a problem is identified, an appropriate matched repair plan is available. This offers the user a more complete service to minimize repair costs and schedule down-time. S O S can also measure the effectiveness of the user's maintenance program.Obtain S O S Sample
Caterpillar recommends using Scheduled Oil Sampling (S O S), at regularly scheduled intervals, to compliment a good preventive maintenance program. There are several methods used to obtain S O S samples. Sampling methods recommended are in preference order. If the first method is not feasible, use the drain stream method.* Use a sampling gun inserted into the sump.* Use the drain stream method when changing oil.When using the drain stream method to obtain an oil sample, take the sample after some oil has drained and before the final drain oil stream. The oil at the beginning or end of the drain stream is not mixed well enough to be representative of circulating oil in the compartment and may carry debris that can give false S O S analysis results.S O S Analysis
S O S is composed of three basic tests:* Wear Analysis* Chemical and Physical Tests* Oil Condition Analysis Wear Analysis is performed with an atomic absorption spectrophotometer to monitor component wear rates by identifying and measuring concentrations, in parts per million, of wear elements present in the used oil.Based on known normal concentration data, maximum limits of wear elements are established. Impending failures can be identified when test results deviate from concentration levels established as acceptable, based on normal wear.Through monitoring the used oil, normal component wear trends are determined. Many failures can be identified when wear trends and/or contaminants significantly exceed past trends.Detectable failures are those caused by component wear and gradual contamination from dirt, fuel, water or antifreeze. Wear analysis is not able to predict failures due to component fatigue, sudden loss of lubrication, or sudden ingestion of a large amount of dirt or contaminants since failures of this nature occur too rapidly. Chemical and Physical Tests detect the
