Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on the following 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 increment is 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.Procedure for Changing the Engine Oil and Filter
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 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.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.

Remove the cap that protects the male coupler . Connect an oil pump to the fitting.
Turn on the oil pump and withdraw the engine oil from the engine crankcase.
Use a strap type wrench to remove both of the used oil filter elements.
Clean the filter mounting base with a clean cloth.

Apply a thin film of clean engine oil to the sealing surface of the new filter element.
Install the new filter elements hand tight until the seals of the engine oil filter contacts the base. Note the position of the index marks on the filter in relation to a fixed point on the filter base. Note: Caterpillar oil filters have rotation index marks on each oil filter. The index marks are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten engine oil filters, use the rotation index marks as a guide.
Tighten the filter according to the instructions that are printed on the
