DISC-GRINDING 4C3805 - Caterpillar

Selection of the Oil Change Interval
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.Refer to this Operation and Maintenance Manual, "Lubricant Viscosities" for further information about oils that may be used in Cat engines.Refer to this Operation and Maintenance Manual, "Severe Service Application" to determine if oil change interval should be reduced from the normal change interval. If operating in any of the conditions or environments outlined in the Severe Service Application, use S O S Services oil analysis to determine the best oil change interval. If S O S Services oil analysis S is not being used, oil change interval should be reduced to 250 hrs.

(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. Ifthe 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.Procedure for Changing the Oil
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot 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.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
Refer to the Operation and Maintenance Manual, "Hood Tilt" for the access to the engine.Park the machine on a level surface and engage the parking brake. Stop the engine.Note: Drain the crankcase while the oil is warm. Waste particles that are suspended in the oil will drain along with the oil. 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.
