You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.S O S Oil Analysis
Obtain Sample
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.
To compliment a good preventive maintenance program, Caterpillar recommends using S O S Oil Analysis at regular scheduled intervals to monitor the condition of the engine oil 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 crankcase.
Typical oil sampling valve.To obtain S O S oil samples: * Use the oil sampling valve (if equipped)* Use a sampling gun inserted into the sump* Use the drain stream when changing oilCaterpillar recommends the use of a sampling valve (if equipped) in order to obtain samples. The quality and the consistency of the samples is better when the sampling valve is used. If a sampling valve is not equipped, the use of an oil sampling gun is preferred. If these methods are not feasible, then use the drain stream method.The drain stream method is the least preferred method because debris from the bottom of the oil sump can contaminate the sample. 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.For more detailed information, refer to PEHP6001, How To Take A Good Oil Sample. Consult with your Caterpillar dealer for complete information and assistance in establishing an S O S program for your engine.Engine Crankcase
Replace Oil and Oil Filter
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.
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
Oil drain plug.1. After the engine has been run at normal operating water temperature, STOP the engine. Place a suitable container beneath the oil drain plug in order to catch the draining oil. Remove the oil drain plug.
Oil filler cap (1), oil filter (2), oil level gauge (dipstick) (3), and oil drain valve (4).2. Open the oil drain valve. Allow the oil to drain.3. After the oil has drained, close the oil drain valve. Install the oil drain plug.Replace Oil Filter
