NOTICE

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.

NOTICE

This machine is equipped with an engine that meets EPA Tier 2, Euro Stage III, or MOC Step 3 emission regulations. A 500 hour engine oil change interval is possible, if the following conditions are met. Acceptable operating conditions, recommended multigrade oil types, and an S·O·S oil sampling and analysis program are used. Otherwise use a 250 hour oil change interval. If you select an interval for oil and filter change that is too long, you may damage the engine.

CAT oil filters are recommended.

Recommended multigrade oil types are listed in Table 1.

Note: Do not use API CF-4 oils in Caterpillar machines with diesel engines.

Abnormally harsh operating cycles or harsh environments can shorten the service life of the engine oil. Arctic temperatures, corrosive environments, or dusty conditions may require a reduction in engine oil change intervals from the recommendations in Table 1. Also refer to Manual, SEBU5898, "Cold Weather Recommendations for all Caterpillar Machines". Poor maintenance of air filters or of fuel filters requires reduced oil change intervals. See your Cat dealer for more information if this product will experience abnormally harsh operating cycles or harsh environments.

⁽¹⁾	The standard oil change interval for engines is 250 hours. The extended oil change interval in this machine is 500 hours if the following conditions are met. Acceptable operating conditions, recommended oil types, and an S·O·S oil sampling and analysis program are used. This extended interval is not permitted for other machines. Refer to the applicable Operation and Maintenance Manuals for the other machines.
⁽²⁾	For sulfur content above 0.1%, refer to this topic in the Manual, SEBU6250, "Caterpillar Machine Fluid Recommendations".
⁽³⁾	Use "Program B" below to determine an appropriate interval.

Adjustment of the Oil Change Interval

Note: Your Cat dealer has additional information on these programs.

Program B

Optimizing Oil Change Intervals

Begin with a standard oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted 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.

Remove the engine oil filter elements from the front left side of the engine. Discard the engine oil filter element properly. Make sure that all of the old filter seal is removed from the filter base.
Apply a thin coat of oil to the seal on the new filter. Install the new engine oil filter element by hand.
Note: Instructions for the installation of the filters are printed on the side of each Caterpillar spin-on filter. For non-Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.

Remove the oil filler cap (2). Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)". Clean the oil filler cap and install the oil filler cap.
Always measure the oil level with dipstick (1) in order to ensure that the correct amount of oil was added.
On the dipstick, always maintain the oil level in the "SAFE OPERATING RANGE" zone.
Reference: See Operation and Maintenance Manual, "Engine Oil Level - Check".
Close the engine access door.
