Oil drain
Open the oil drain. After the oil has drained, close the oil drain.
If a suction device is inserted into the oil pan, ensure that the suction device is clean. Using a clean suction device will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If a suction device that attaches to the oil drain is used, ensure that the suction device is clean. Attach the suction device to the oil drain. Open the oil drain. After the oil has drained, close the oil drain and remove the suction device. Replace the Oil Filter Elements

Mounting base and gasket
Clean the sealing surface of the mounting base. Ensure that all of the old gasket is removed.
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
Apply clean engine oil to the gasket of the new oil filter.
Do not fill the oil filters with oil before installing them. This oil would not be filtered and could be contaminated. Contaminated oil can cause accelerated wear to engine components.
Place the oil filter in position. Tighten the oil filter until the gasket contacts the base. Tighten the oil filter by hand for an additional 3/4 turn (270 degrees). Do not overtighten the oil filter. Inspect the Used Oil Filter Elements
Cut the used oil filter element open with a 4C-5084 Oil Filter Cutter. Spread apart the pleats and inspect the filter material for metal debris. An excessive amount of debris in the element may indicate early wear or a pending failure.
Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the filter. Ferrous metals may indicate wear on the steel and the cast iron parts of the engine. Nonferrous metals may indicate wear on the aluminum parts, the brass parts, or the bronze parts of the engine. Parts that may be affected include the following components: main bearings, rod bearings, turbocharger bearings and cylinder heads. Small amounts of debris in the oil filter due to normal wear and friction. If an excessive amount of debris is found, consult your Cat dealer in order to arrange for further oil analysis.Fill the Crankcase
Use only oils that are recommended by Caterpillar. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for information about choosing the correct oil for the engine.
If the engine is equipped with an auxiliary oil filter system, extra oil must be added when filling the crankcase. If equipped with an auxiliary oil filter system that is not supplied by Caterpillar, follow the recommendations of the OEM.
Engine damage can occur if the crankcase is filled above the "FULL" mark on the
