Obtain the Sample and the Analysis
In addition to a good preventive maintenance program, Caterpillar recommends using S O S oil analysis at regular scheduled intervals in order to monitor the condition of the engine and the maintenance requirements of the engine.To ensure that the sample is representative of the oil in the crankcase, obtain a warm, well mixed oil sample.Obtain the S O S Sample
Use one of the following methods in order to obtain an S O S sample:
Illustration 1 g00403338
Typical oil sampling valve
Use the oil sampling valve (if equipped).
Use a 1U-5758 Vacuum Pump or use an equivalent pump that is inserted into the sump.Caterpillar recommends using a sampling valve in order to obtain oil samples. The quality and the consistency of the samples is better when the sampling valve is used. The location of the sampling valve must allow oil that is flowing under pressure to be obtained during normal engine operation.If the engine is not equipped with a sampling valve, the use of a 1U-5758 Vacuum Pump is preferred.To avoid contamination of the oil samples, the tools and the supplies that are used for obtaining oil samples must be clean.
