Selection of the Oil Change Interval
| NOTICE |
|---|
A 500 hour engine oil change interval is achievable if normal operating conditions are met, recommended multigrade oil types are used, and an S·O·S oil sampling analysis program is utilized. Normal operating conditions include load factors below 40%, idle time below 40%, fuel sulfur levels below 0.3%, and altitude below 1830 m (6000 ft). When these requirements are not met, shorten the oil change interval and use an S·O·S Services oil sampling and analysis program to determine an acceptable change interval. For assistance with optimizing oil change intervals, contact your local Cat dealer. For sulfur content above 0.1 % refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations". |
The normal engine oil change interval is listed in this Operation and Maintenance Manual, "Maintenance Interval Schedule".
Abnormally harsh operating cycles or harsh environments can shorten the service life of the engine oil. Arctic temperatures, corrosive environments, or extremely dusty conditions may require a reduction in engine oil change intervals. Also refer to Special Publication, SEBU5898, "Cold Weather Recommendations for All Caterpillar Machines". Poor maintenance of air filters or of fuel filters requires reduced oil change intervals. Consult your Caterpillar dealer for more information if this product will experience abnormally harsh operating cycles or harsh environments.

Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.
Cat oil filters are recommended.
Program A
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 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 the "Lubricant Viscosities for Ambient Temperatures" Table in this Operation and Maintenance Manual
Program B
Optimizing Oil Change Intervals
Begin 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 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.

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. |

| 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. |
- Park the machine on a level surface and engage the parking brake. Stop the engine.
Note: Drain the crankcase while the oil is warm. The warm oil will allow 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 is located under the engine compartment toward the rear of the machine.
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 and clean the area around the drain valve.
- Open the engine access door on the left side of the machine.
- 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.

Engine oil filters | |
- Clean the filter housing base. All of the seal material must be removed.
- Apply a thin coat of engine oil to the new filter seal.

| Illustration 3 | g00101502 |
- Install the new oil filter by hand.
Instructions for the installation of the filter are printed on the side of each Cat spin-on filter. For filters that are not Cat branded, refer to the installation instructions that are provided by the supplier of the filter.
- Repeat steps 6 through 7 for the oil other filter.
- Close the engine access door.
- Open the engine access door located on the right side of the machine.

- Remove oil filler cap (1) . Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)" and Operation and Maintenance Manual, "Lubricant Viscosities". Clean the oil filler plug and install the oil filler plug.
- Start the engine and allow the oil to warm. Check the engine for leaks. Stop the engine.
| NOTICE |
|---|
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage. |
- Wait for 30 minutes in order to allow the oil to drain back into the crankcase. Check the oil level with oil level gauge (1) . Maintain the oil level in the shaded area (A) of the oil level gauge. If necessary, add oil.
