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. Dispose of all fluids according to local regulations and mandates. |

|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Do not drain the engine lubricating oil when the engine is cold. As the engine lubricating oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with draining cold oil. Drain the oil pan with the engine stopped. Drain the oil pan with the oil warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.
Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.
Drain the Engine Lubricating Oil
Note: Ensure that the vessel that will be used is large enough to collect the waste oil.
After the engine has been run at the normal operating temperature, stop the engine. Use one of the following methods to drain the engine oil pan:

Typical example | |
- If the engine is equipped with a drain valve (2), turn the drain valve knob counterclockwise in order to drain the oil. After the oil has drained, turn the drain valve knob clockwise in order to close the drain valve.
- If the engine is not equipped with a drain valve, remove the oil drain plug (1) in order to allow the oil to drain. If the engine is equipped with a shallow oil pan, remove the bottom oil drain plugs from both ends of the oil pan.
After the oil has drained, the oil drain plug should be cleaned and installed. If necessary, replace the O ring seal. Tighten the drain plug to
Remove the container and disposal of the waste oil in accordance with local regulations.

Cat 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, and so forth, as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar. |
- Place a suitable container below the oil filter assembly. Remove the oil filter with a suitable tool.

NOTICE 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 new oil filter (3). Spin on the oil filter until the O ring contacts the sealing surface (2). Then rotate the oil filter ¾ of a full turn. Remove the container and disposal of the waste oil in accordance with local regulations.
- Place a suitable container below the oil filter assembly. Remove the drain plug (1) and allow the oil to drain.
- Remove the oil filter with a suitable tool.
- Install the drain plug (1) and tighten to a torque of

- Remove the oil filler cap. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for more information on suitable oils. Fill the oil pan with the correct amount of new engine lubricating oil. Refer to this Operation and Maintenance Manual, "Refill Capacities" for more information on refill capacities.

NOTICE If equipped with an auxiliary oil filter system or a remote filter system, follow the OEM or the filter manufactures recommendations. Underfilling or over filling the crankcase with oil can cause engine damage.
- Start the engine and run the engine at "LOW IDLE" for 2 minutes. Perform this procedure to ensure that the lubrication system has oil and that the oil filters are filled. Inspect the oil filter for oil leaks.
- Stop the engine and allow the oil to drain back to the oil pan for a minimum of 10 minutes.
