Scheduled Oil Sampling (S O S) Analysis
For Naturally Aspirated engines, this maintenance should be performed at the Every 500 Hours maintenance interval.For turbocharged engines, this maintenance should be performed at the Every 250 Hours maintenance interval.Obtain Sample and Analysis
To compliment a good preventive maintenance program, Caterpillar recommends using S O S oil analysis at regular scheduled intervals to monitor the condition and maintenance requirements of your engine. 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 compartment.
Typical oil sampling valve.To obtain S O S samples:* Use the oil sampling valve (if equipped)* Use a sampling gun inserted into the sump* Use the drain stream when changing oilCaterpillar recommends using the first or second method. If these methods are not feasible, then use the drain stream method. When using the drain stream method to obtain the oil sample, do not sample from the first or final draining. 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.Consult your Caterpillar dealer for complete information and assistance in establishing an S O S program for your engine.Engine Crankcase
For Naturally Aspirated engines, this maintenance should be performed at the Every 500 Hours maintenance interval.For turbocharged engines, this maintenance should be performed at the Every 250 Hours maintenance interval.This maintenance should be performed on as level a surface as possible.Replace Oil and Filter(s)
Do not drain oil when the engine is cold. As oil cools, suspended waste particles settle on the bottom of the crankcase or oil pan. The waste particles are not removed with the draining cold oil. Drain the crankcase with the engine stopped and the oil warm. This allows for the draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure would result in these waste particles being recirculated through your engine lubrication system with the new oil.Drain Oil
