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. |
Note: Customers with a fuel burn average of
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.

| (1) | The standard oil change interval in this machine is 500 hours, if the operating conditions and recommended oil types that are listed in this table are met. Improvements in the engine allow this engine oil change interval. This new standard interval is not permitted for other machines. Refer to the applicable Operation and Maintenance Manuals for the other machines. |
| (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. |
Adjustment of the Oil Change Interval
Note: Your Cat dealer has additional information on these programs.
Verification for an Oil Change Interval of 500 Hours
This 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 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.
Optimizing Oil Change Intervals
Begin 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 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 in the listing above.
Procedure for Changing Engine Oil and Filter
 |
|
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. Warm oil 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.

The 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.

NOTICE Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
- Start the engine and allow the oil to warm. Check the engine for leaks. Stop the engine.

Illustration 8 g02153764 - Wait for 30 minutes in order to allow the oil to drain back into the crankcase. Check the oil level with the dipstick. Maintain the oil between the "L" and "H" marks on the dipstick. If necessary, add oil.
- Close the engine hood and latch the engine hood.
If your machine is equipped with a deluxe service center, you may drain the engine oil through the fast fill port. You may also add the engine oil through a fast fill port.
