To compliment a good preventive maintenance program, Caterpillar recommends using S»OS at regular scheduled intervals to monitor the condition and maintenance requirements
of your engine.
OBTAIN SAMPLE
Each oil sample should be taken when the oil is warm and well mixed to ensure that the sample is representative of the oil in the crankcase
There are two methods recommended to obtain S»OS samples from the engine crankcase.
Gambar
1. Use the sampling valve installed on the engine for samples 2. Use a sampling gun inserted into the sump.
Caterpillar recommends using one of these methods. If either of these methods are not possible, then use a drain stream method when changing oil.
NOTE: When using the drain stream to obtain the oil sample, do not sample from the first or final drain stream. The oil at the beginning or end of the drain stream is not mixed well
enough to be representative of the oil in the crankcase. SOS INTERVAL CHART
