After the engine has been operated at normal operating temperature, STOP the engine.
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, "Cat Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Cat Shop Supplies and Tools 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. After the oil has drained, install the oil drain plug and tighten the plug. Refer to Specifications Manual, SENR3130 for the correct torque.Replace the Oil Filter
Remove the oil filter with a 1U-8760 Chain Wrench.
Cut the oil filter open with a 175-7546 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 bearings of the front idler gear.Normal wear and friction may cause small amounts of debris in the oil filter element. If an excessive amount of debris is found in the oil filter element, consult your Cat 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 filters recommended by Caterpillar.
Apply clean engine oil to the new oil 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 can cause accelerated wear to engine components.
Install the oil filter. Tighten the oil filter until the oil filter gasket
