Scheduled Oil Sampling (S O S)
Obtain Oil Sample and Analysis
To compliment a good preventive maintenance program, Caterpillar recommends using S O S at regular scheduled intervals to monitor the condition of the engine oil 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 oil samples.* Use the sampling valve (if equipped).* Use a sampling gun inserted into the sump.The sampling valve should be flushed with engine oil to rinse the dirt and debris from the valve.Caterpillar recommends using one of the methods previously mentioned. However, if either of these methods are not possible, then use a drain stream method when changing the oil. When using the drain stream to obtain the oil sample, do not sample from the beginning or end of 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.Consult your Caterpillar dealer for complete information or assistance in establishing an S O S oil analysis program for your engine.Oil Change Intervals
Lubrication oil and oil filters should be replaced every 200 service hours or less for engines operating at an altitude of 1830 m (6000 ft) or higher.
In areas where the fuel sulfur exceeds 1.5 percent, choose an oil with the highest TBN that is within the API CF-4 or CG-4 categories, and shorten the oil change period based on oil analysis. High TBN oils that are not within the API CF-4 or CG-4 categories can produce excessive piston deposits leading to a loss of oil control and bore polishing.
Operation at fuel sulfur levels over 1.0 percent may require shortened oil change periods to maintain adequate wear protection.
Oil change intervals should be adjusted according to S O S results. It is essential that an S O S analysis be performed to analyze oil condition before oil change period adjustment is considered.Due to manufacturing tolerances, engine application and maintenance variation, all engines do not consume fuel and oil at the same rate. Some history of fuel and oil consumed for each engine (or group of engines) in a similar application must be established.For a group of engines, determine the average fuel consumption and add oil rate. This is performed by dividing the total quantity of fuel or oil consumed by the operating (service) hours of the engines.Consult with your Caterpillar dealer for more information on adjusting oil change intervals for specific applications.Engine Crankcase
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
After the engine has been run at normal operating temperature, STOP the engine. The method you use to drain your engine's crankcase oil depends on your engine equipment.* If equipped with a drain valve, turn the valve knob counterclockwise (CCW) to drain the oil. After the oil has drained, turn the valve knob clockwise (CW) to close the drain.* If not equipped with a drain valve, remove the oil drain plug(s) and allow the oil to drain. After the oil has drained, clean the oil drain plug(s). Clean the oil drain plug fitting(s). Install the oil drain plug(s). Tighten the plug(s) to 25 5 N m (18 4 lb ft).Replace Filter
Replace oil filter(s) at every oil change. Make sure to use the correct oil filter(s) for your engine arrangement.
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to your engine bearings, crankshaft, etc., as a result of the larger debris particles from unfiltered oil entering your engine lubricating system. Only use oil filters recommended by Caterpillar.
1. Remove the oil filter and remove the optional oil filter (if equipped) with a 1U-8760 Chain Wrench.
Element with debris.2. Cut the oil filter open with a 4C-5084 Oil Filter Cutter. Spread the pleats apart and inspect the element for metal debris. An excessive amount of debris in the oil filter element may indicate early wear or a pending failure.Use a magnet to differentiate between the ferrous and non-ferrous metals found in your oil filter element. Ferrous metals may indicate wear on the steel and cast iron parts of your engine.Non-ferrous metals may indicate wear on the aluminum, brass or bronze parts of your engine, such as main and rod bearings, turbocharger bearings and cylinder heads.Due to normal wear and friction, it is not uncommon to find small amounts of debris in the oil filter element. Consult your Caterpillar dealer to arrange for further analysis if an excessive amount of debris is found in your oil filter element.
Typical filter mounting base and filter gasket.3. Clean the sealing surface of the filter mounting base. Make sure all of the old gasket is removed.4. Apply a small amount of clean engine oil to the new filter gasket.
Do NOT fill the oil filters with oil before installing them. This oil would not be filtered and could be contaminated. Contaminated oil will cause accelerated wear to engine components.
5. Install the new filter(s) until the gasket contacts the base. Hand tighten the filter and additional 3/4 of a turn (270 degrees). Do not over tighten. Use the rotation index marks on the filter as a guide to proper tightening.Fill Crankcase
1. Remove the oil filler cap. Refer to Lubricant Specifications for the proper oil to use for this engine. Fill the crankcase with the
