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.
Do not drain the oil when the engine is cold. As the oil cools, 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 when the oil is warm. This method allows proper draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine. Note: Drain the oil into a suitable container. DO NOT drain the oil into the bilge sump.Note: If a suction device is used to remove the oil from the oil pan, ensure that the suction device is clean. Using a clean suction device prevents dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
Open the oil drain valve. After the oil has drained, close the valve
Drain the oil according to the equipment on the engine. If the engine has a pump for removing dirty oil, connect a hose to the outlet of the pump. Place the hose in a suitable container. Open the valve for the drain line. The two marks on the valve must be turned so that one mark points to the pump. The second mark points to the drain line. Operate the pump until the crankcase is empty. Close the valve to the drain line. Disconnect the hose.
Replace the engine oil filter elements before filling the crankcase with new oil. Replace the Oil Filter Elements
Replace the engine oil filters at every engine oil change.Note: Do not attempt to clean the used oil filters. Used oil filters will retain waste particles. The used oil filters would not filter the oil properly.Note: Do not fill the engine oil filters with oil prior to installation.Service tools are available to aid in the service of oil filters. Consult your Cat dealer for the part names and the part numbers. Follow the instructions that are supplied with the service tools. If the service tools are not used, perform the following appropriate procedure.Replacing the Engine Oil Filters With the Engine Stopped (Standard Oil Filters)
Perform the following procedure after the oil has been drained.
Remove used oil filters and properly discard the used oil filters.

Typical filter mounting base and filter gasket
Clean the sealing surface of the filter mounting base. Make sure that the former oil filter gaskets are removed.
Apply a thin film of clean engine oil to the seal of each new 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 or engine damage.
Install the filters by hand. Tighten each filter according to the instructions that are printed on the filter. Note: A Cat strap wrench, or another suitable tool, to turn the filters to the amount that is required for final installation may be required. Make sure that the installation tool does not damage the filters. Do not overtighten the oil filter.Replacing the Engine Oil Filters During Engine Operation (Duplex Oil Filter System Only)
This filter contains hot, pressurized oil that can cause burns and fire hazards, which may result in bodily injury or death. Follow the instructions given in this Operation and Maintenance Manual and stop the engine if rapid air movement exists to blow the oil.
If the engine is equipped with duplex oil filters, the engine oil filter elements can be changed while the engine is in operation.

(9) "AUXILIARY RUN" for Filter 2
(10) "MAIN RUN" for Filter 2
Main Run Filter 1 - The oil selector valve is in this position at the start of the oil filter change procedure for Filter 2. 100% of the oil flows to Filter 1.
Auxiliary Run for Filter 1 - A small stream of oil fills Filter 2 with most oil flowing through Filter 1.
Both Flow - Normal position for engine operation. Oil is flowing equally to Filter 1 and to Filter 2.
Auxiliary Run Filter 2 - A small stream of oil fills Filter 1 with most oil flowing through Filter 2.Show/hide ta
