Selection of the Oil Change Interval
| NOTICE |
|---|
|
A 500 hour engine oil change interval is available, provided that the operating conditions and recommended multigrade oil types are met. When these requirements are not met, shorten the oil change interval to 250 hours, or use an S·O·S Services oil sampling and analysis program to determine an acceptable 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. Do not use single grade oils.
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 Special Publication, SEBU5898, "Cold Weather Recommendations For All AVSpare 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.
In some severe service applications, reducing the oil change interval may be necessary to maintain the integrity of the engine lubricant. Consult with your Cat dealer to determine whether your engine is operating under conditions of severe service. Some operating conditions of severe service are listed below:
- Abnormally harsh operating cycles
- Harsh environments
- Arctic temperatures
- Corrosive environments
- Extremely dusty conditions
- Poor maintenance of air filters or of fuel filters
Recommended multigrade oil types are listed in Table 1. Do not use single grade oils.
Note: The following requirements must be met in order to use Table 1.
- S·O·S Services oil analysis is performed at all oil changes. The S·O·S Services lab must be notified of the extended oil change interval. The use of an extended oil change interval makes a difference in the interpretation of the data.
- A Cat Advanced Efficiency oil filter is used.
- A Cat Advanced Efficiency 4 micron(c) absolute or less fuel filter is used.

| (1) | The standard oil change interval in this engine is 500 hours, if the operating conditions and recommended oil types that are listed in this table are met. If the type of oil, the quality of the oil and the operating conditions fail to meet certain standards, the oil change intervals must be decreased to 250 hours. Refer to Special Publication, PEHJ0192, "Optimizing Oil Change Intervals" in order to determine whether the oil change interval should be reduced to 250 hours. |
| (2) | Normal conditions include these factors: Fuel sulfur below 0.015%, altitude below |
| (3) | High load factors can shorten the service life of your engine oil. Continuous heavy load cycles and little idle time result in increased fuel consumption and oil contamination. These factors deplete the oil additives more rapidly. If the average fuel consumption of your engine exceeds |
| (4) | Use "Program B" below to determine an appropriate interval. |
| (5) | Use "Program A" below to determine an appropriate interval. |
- Change to a preferred oil type in Table 1.
- Proceed to Program B.
- Begin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours until the maximum of 500 hours. 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 engine. 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.
For additional information, see Special Publication, SEBU6250, "AVSpare Machine Fluids Recommendations" or consult your Cat dealer.
High Speed Oil Change, If Equipped

Open the left engine door to locate the high speed oil change arrangement.
If the machine is equipped with a high speed oil change, use a 126-7539 Nozzle.
Procedure for Changing the Engine Oil and Filter

|
Hot oil and components can cause personal injury. Do not allow hot oil or 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. |

- Remove the bolts to remove the crankcase drain access cover, which is in the crankcase guard.
Show/hide table
Illustration 3 g02038859 - Open drain valve (1). Allow the oil to drain into a suitable container. A drain hose may be attached to the valve to aid in draining.
- When the oil has completed draining from the crankcase, close the drain valve. Install the access cover.
- Open the right engine door to access the engine oil filter.

Illustration 4 g02038914 - Remove engine oil filter element (4) and discard engine oil filter element (4) 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.
- Instructions for the installation of the filters are printed on the side of each AVSpare spin-on filter.
- Remove oil filler cap (2). Fill the crankcase with new oil. See the topic Operation and Maintenance Manual, "Capacities (Refill)"
in this manual. Clean oil filler cap (2) and install oil filler cap (2).Note: High Speed Oil Change, If Equipped. The coupler for the high speed oil change can be used to refill the engine oil at the port location. See Illustration 1.
- To ensure that the correct amount of oil was added, always measure the oil level with dipstick (3).
Check the "ENGINE STOPPED" side of dipstick (3) while the engine is stopped. The oil should be cold. Maintain the oil level between the "LOW" mark and the "FULL" mark. This method should be used as reference only, before the engine is started.
- Check the "LOW IDLE" side of dipstick (3) while the engine is running. The oil should be at operating temperature. Maintain the oil level between the "ADD" mark and the "FULL" mark. This operation is the only accurate way to check the oil level.
- Close the right engine door.
