Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.Cat oil filters are recommended.Program A
Verification for an Oil Change Interval of 500 HoursThis program consists of three oil change intervals of 500 hours. Oil sampling and analysis are done at 250 hours and 500 hours for each of the three intervals for a total of six oil samples. The analysis includes oil viscosity and infrared (IR) analysis of the oil. If all of the results are satisfactory, the 500 hour oil change interval is acceptable for the machine in that application. Repeat Program A if you change the application of the machine.If a sample does not pass the oil analysis, take one of these actions:
Shorten the oil change interval to 250 hours.
Proceed to Program B.
Change to a preferred oil type in the "Lubricant Viscosities for Ambient Temperatures" Table in this Operation and Maintenance ManualProgram B
Optimizing Oil Change IntervalsBegin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each increment is an additional 50 hours. Periodic oil sampling and analysis are done during each interval. The analysis includes oil viscosity and infrared (IR) analysis of the oil. Repeat Program B if you change the application of the machine.If an oil sample does not pass the analysis, shorten the oil change interval, or change to a preferred multigrade oil type.References

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Care must be taken to ensure that all fluids are contained during performance of inspection, maintenance, testing, adjusting and the 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.
Note: Be sure that you obtain a S O S engine oil sample before you drain the engine oil.
Park the machine on a level surface and engage the parking brake. Stop the engine.

The drain valve (1) for the engine oil is located underneath the engine compartment toward the rear of the machine. Open the drain valve and allow the oil to drain into a suitable container.
Close the drain valve and clean the area around the drain valve.
The engine oil filters (2) are located underneath the engine compartment toward the rear of the machine.
Remove the oil filter elements and discard the filters properly. Make sure that the old seal is removed from the filter base.
Install new filters.
Apply a thin coat of oil to the seals on the new filters.
Install the new engine oil filters hand tight until the seal of the engine oil filter contacts the base. Note the position of the index marks on
