Drain the Oil
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
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.
Drain the oil according to the equipment on the engine.Note: Drain the oil into a suitable container. Dispose of the oil according to local regulations.

Oil drain valve
Note: If a suction device is used, ensure that the device is clean to keep contaminants out of the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If the engine does not have a drain valve or a pump, remove an oil drain plug. Allow the oil to drain. After the oil has drained, clean the drain plug and clean the fitting for the drain plug. Install the drain plug. Tighten the drain plug to 145 15 N m (105 10 lb ft).
Loosen or remove the oil level gauge.
If the engine has an oil drain valve, open the valve. After the oil has drained, close the valve.
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. Turn the two marks on the valve so that one mark points to the pump and 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.
If the oil drain valve has a quick-connect coupling, attach the coupling. Open the drain valve to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.
Replace the engine oil filter elements before filling the crankcase with new oil.Replace the Oil Filter Elements
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Ensure that the engine is stopped before performing this procedure. Attach a DO NOT OPERATE tag to the starting controls.

Mounting base and gasket
Clean the sealing surface of the mounting base. Ensure that all the old gasket is removed.
Apply clean engine oil to the gasket of the new 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 the oil filter in position. Tighten the oil filter by hand until the gasket contacts the base. Tighten the oil filter by hand for an extra 1 full turn (360 degrees). Do not overtighten the oil filter.
Check the oil level according to the instructions in this Operation and Maintenance Manual, "Engine Oil Level - Check".Inspect the Used Oil Filter Elements
Cut the used oil filter element open with a Cat filter cutting tool.Remove the metal wrap. Cut the filter element free from the end caps. Spread apart the pleats and inspect the element for metal debris. Due to normal wear and friction, small amounts of debris may be found in the oil filter element. Early wear may be indica
