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.
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 draining method allows the waste particles that are suspended in the oil to be drained properly. 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. Dispose of fluids according to local regulations.
Drain the oil by using one of the following methods. Use the method that corresponds to the equipment on the engine. Note: If a suction device is used in order to remove the oil from the oil pan, ensure that the suction device is clean. This will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
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 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. 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 in order to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.
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). Note: Ensure that the dirty oil is thoroughly drained from the pan. Caterpillar recommends a thorough cleaning of the oil pan with a vacuum and with rags in order to completely remove all of the old oil. This will help prevent inaccurate oil analysis results and/or shortened life of the oil.
Replace the engine oil filter elements before filling the crankcase with new oil.
For the procedure to change the engine oil filters, refer to the Operation and Maintenance Manual, "Engine Oil Filter - Change" topic (Maintenance Section).
Engine damage can occur if the crankcase is filled above the "FULL" mark on the oil level gauge (dipstick).An overfull crankcase can cause the crankshaft to dip
