GEAR-WORM 6G1538 - Caterpillar

The oil change interval will be affected by the following items:
Air/fuel ratio
Ambient air conditions
Engine application
Fuel type
Oil type
Size of the oil sumpNote: For engines that operate at high load factors of 80 percent or more for extended periods of time perform the following: decrease the interval between oil changes by 20 percent and increase the API service classification of the oil. Refer to Caterpillar Publication, PEHJ0191, "CAT S O S Fluid Analysis" in order to understand optimizing oil change intervals.The S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine. In the absence of S O S oil analysis, change the engine oil and filters according to Table 1.

or
Every 92 Day FRA Inspection    Drain the Oil
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This method allows proper draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
Drain the oil according to the equipment on the engine. See the literature that is provided by the OEM of the locomotive.
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.
Open the oil drain. After the oil has drained, close the oil drain.
If a suction device is inserted into the oil pan, ensure that the device is clean. A clean suction device will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If a suction device that attaches to the oil drain is used, ensure that the suction device is clean. Attach the suction device to the oil drain. Open the oil drain. After the oil has drained, close the oil drain and remove the suction device.
If the oil drain valve has a quick connect coupler, attach the coupling. Open the drain valve in order to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.Replace the Oil Filter Elements
