Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.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 is 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 Table 1.Program B
Optimizing Oil Change IntervalsBegin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours. Periodic oil sampling and analysis is 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 in the listing above.References

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Note: If the sulfur content in the fuel is greater than 1.5 percent by weight, use an oil that has a TBN of 30 and reduce the oil change interval by one-half.Note: Drain the crankcase while the oil is warm. This allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining the oil and the particles will recirculate in the engine lubrication system with the new oil.
Illustration 1 g01132441The drain valve for the engine crankcase oil is located under the rear of the upper structure.
Park the machine on a level surface. Stop the engine. Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information on Containing Fluid Spillage.

Open the crankcase drain valve. Allow the oil to drain into a suitable container. Note: Discard any drained fluids according to local regulations.
Close the drain valve.
Open the access door at the right side of the machine.
Illustration 3 g01120941
Remove the oil filter with a strap type wrench. See Operation and Maintenance Manual, "Oil Filter - Inspect". Dispose of the used filter according to local regulations.
Clean the filter housing base. Make sure that all of the old filter gasket is removed.

Apply a thin coat of engine oil to the gasket of the new filter. Note: There are rotation index marks
