Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase with the oil warm, immediately after the engine is stopped. This method of draining allows the waste particles that are suspended in the oil to be drained.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Drain the oil.
If the engine has an oil drain valve, open the valve in order to drain the oil. After the oil has drained, close the valve.
If the engine does not have a drain valve, remove an oil drain plug. Allow the oil to drain. Replace the Oil Filter
Remove the oil filter with a 1U-8760 Chain Wrench.
Cut the oil filter open with a 4C-5084 Oil Filter Cutter. 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.Aluminum debris may indicate problems with the bearings of the front gears. If you find aluminum debris, inspect the vibration damper and the idler gear bearings. Due to normal wear and friction, it is not uncommon to find small amounts of debris in the oil filter element. If an excessive amount of debris is found in the oil filter element, consult your Caterpillar dealer in order to arrange for further oil analysis.

Typical filter mounting base and filter gasket
Clean the sealing surface of the filter mounting base. Ensure that all of the old oil filter 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
