SEAL 8T9502 - Caterpillar

Note: The maintenance interval is correct for engines operating with fluids preferred by Caterpillar. If the fluids being used are not preferred, refer to this Operation and Maintenance Manual, "Severe Service Application" for further information about a reduction the oil change interval.Caterpillar recommends using Cat S O S Services oil analysis at regularly scheduled intervals in order to monitor the condition and maintenance requirements of the engine. S O S oil analysis provides infrared analysis, which is required for determining nitration and oxidation levels. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for more information about the use of S O S oil analysis.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the 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 with the draining cold oil. Drain the crankcase with the engine stopped. Drain the crankcase with the oil warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.Drain the Engine Oil
After the engine has been run at the normal operating temperature, stop the engine. Attach a "DO NOT OPERATE" or a similar warning tag to the ignition keyswitch before the engine is serviced.
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.
Remove the oil drain plug in order to allow the oil to drain.
After the oil has drained, the oil drain plug should be cleaned and installed. Replace the Oil Filter
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
