(1) The capacity includes the oil sump plus oil filters that are installed at the factory. Engines with auxiliary oil filters will require additional oil. The capacity is approximate. The actual capacity may vary by five percent. Caterpillar recommends using the capacity that is listed and then adjusting the oil level according to the oil level gauge (dipstick).
(2) Use this oil change interval in the absence of oil analysis.Change the Engine Oil
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
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. This method allows the waste particles that are suspended in the oil to properly drain.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.
Ensure that the engine is stopped before performing this procedure. Attach a DO NOT OPERATE tag to the starting controls.
Note: Drain the oil into a suitable container. Dispose of fluids according to local regulations.

(1) Drain valve
Open drain valve (1) in order to drain used oil. After the oil has drained, close drain valve (1). 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 the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
Clean the oil suction screen. Note: Approximately 1 L (1 qt) of oil will remain in the housing after the sump has been completely drained. This oil will pour out of the housing when the cover for the oil suction screen is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with absorbent towels or pillows. DO NOT use absorbent particles to clean up the oil.

(2) Cover
(3) Seal
(4) Screen
Remove cover (2) and seal (3). Discard the used seal. Slide screen assembly (4) from the tube.
Wash the screen assembly in clean nonflammable solvent. Allow the screen assembly to dry before installation.
Clean the bottom of the sump. Remove side covers in order to gain access to the sump. When the bottom of the sump is clean, install the side covers.
Install the oil suction screen. Install the cover and a new seal.
Change the engine oil filters. See this Operation and Maintenance Manual, "Engine Oil Filter - Change" topic (Maintenance Section).
Clean the centrifugal oil filters.
Disassemble the centrifugal oil filters according to the instructions in the Service Manual.
Thoroughly clean all of the parts of the centrifugal oil filter. Carefully inspect all of the parts.
Ensure that all of the rotor components are thoroughly clean before assembling the rotor. Failure to do so can cause an out of balance condition that can cause rapid wear to the bearings and the spindle.
Note: Install a new paper liner when the centrifugal oil filter is assembled.
Assemble the centrifugal oil filters according to the instructions in the Service Manual.
Only use oils that are recommended by Caterpillar. For the proper oil to use, refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" topic (Maintenance Section).
Engine damage can occur if the crankcase is filled ab
