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.
Connect a drain hose to the oil filter housing drain (2). Drain the oil into a suitable container.
Unscrew the oil filter housing (3).
Remove the oil filter element (5).
Break apart the pleats and inspect the oil filter for metal debris. An excessive amount of metal debris in the oil filter 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 oil filter element. Ferrous metals may indicate wear on the steel and cast iron parts of the engine.Nonferrous metals may indicate wear on the aluminum parts, brass parts, or bronze parts of the engine. Parts that may be affected include the following items: main bearings, rod bearings, turbocharger bearings, and cylinder heads.Due to normal wear and friction, finding small amounts of debris in the oil filter is not uncommon. Consult your Cat dealer to arrange for a further analysis if an excessive amount of debris is found in the oil filter.
Clean the sealing surface of the filter mounting base.
Apply clean engine oil to the new oil filter element O-ring seal.Install the oil filter element.
Inspect the oil filter housing o-ring. Replace the o-ring if damaged.
Screw oil filter housing into the base.
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 or engine damage.
Tighten the oil filter housing to 60 5 N m (44 3.6 lb ft).Fill the Engine Crankcase
Remove the oil filler cap. Fill the crankcase with the proper amount of oil. Refer to the Operation
