After the engine has been run at the normal operating temperature, stop the engine. Attach a "DO NOT OPERATE" or a similar warning tag to the ignition keyswitch before the engine is serviced.
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 using the drain plug (1) on the oil sump (2) .
After the oil has drained, secure the drain plug.Replace the Oil Filter

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.
Place a suitable container under the oil filter drain plug. Loosen oil filter drain (2). Drain oil into the container. Tighten oil filter drain plug. Torque the drain plug 5 N m (3.6 lb ft) to 8 N m (6 lb ft).
Unscrew the oil filter assembly (1) .
Remove the oil filter assembly.
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 in order 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 O-ring seal.
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 assembly. Torque the oil filter assembly 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 and Maintenance Manual, "Refill Capacities" for the correct refill capacities. Refer to the Operation and Maintenance Manual, "Fluid Recommendations" for the correct oil.
If equipped with an auxiliary oil filter or system, extra oil must be added when filling the crankcase. Follow the OEM or filter manufacturer's recommendations. If the extra oil is not added, the engine may starve for oil.
To help prevent crankshaft or bearing damage, crank engine to fill all filters before starting. Do not crank engine for more than 30 seconds.
Start the engine and run the engine at "LOW IDLE" for 2 minutes. Perform this procedure in order to ensure that the lubrication system has oil and that the oil filters are filled. Inspect the oil filter for oil leaks.
Stop the engine and allow the oil to drain back to the sump for a minimum of 10 minutes.
Remove the oil level gauge in order to check the oil level. Maintain the oil level between the "ADD/MIN" and "FULL/MAX" marks on the side of the oil level gauge.
