BOLT 8T4956 - Caterpillar

If the engine is equipped with duplex oil filters, the engine oil filter elements can be changed while the engine is in operation. Refer to "Replacing the Engine Oil Filters During Engine Operation".The oil change interval can be affected by several factors:
Air/fuel ratio
Ambient air conditions
Engine application
Fuel type
Oil type
Size of the oil sumpThe 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 the interval that is listed in Table 1. Refer to this Operation and Maintenance Manual, "Refill Capacities" to determine the size of the oil pan.

Drain the Oil
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, "Cat Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Cat Shop Supplies and Tools 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 drain the oil when the engine is cold. As the oil cools, 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.
