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.
Note: Engine oil and filter change interval can be extended to 1400 - 1700 hours using Cat recommended oil. Engine oil and filter change interval can also be extended to 2000 hours using external sump option with Cat recommended oil.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.
Drain the oil by using one of the following methods. Use the method that corresponds to the equipment on the engine.Note: Drain the oil into a suitable container. Dispose of fluids according to local regulations.Note: If a suction device is used to remove the oil from the oil pan, ensure that the suction device is clean. This procedure 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, remove the oil drain plug and open the valve 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 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 80 12 N m (59 9 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 to remove all the old oil. This process will help prevent inaccurate oil analysis results and/or shortened life of the oil.Replace the Engine Oil Filters
