SEBU7899-05 83 Maintenance Section Engine Oil and Filter - Change Interval for Engine Oil and Engine Oil Filter Change If the engine is not equipped with a drain valve, remove the oil drain plug in order to allow the oil to drain. If the engine is equipped with a shallow sump, remove the bottom oil drain plugs from both ends of the oil pan. Note: The intervals stated in table 20 are only valid when preferred lubricants are used. Using fluids other than the preferred fluids causes the engine to operate in a severe service application.
Refer to this Operation and Maintenance Manual, “Severe Service Application” for information about the effect of using fluids which are not preferred on the maintenance intervals. After the oil has drained, the oil drain plugs should be cleaned and installed. Replace the Oil Filter Refer to this Operation and Maintenance Manual, “Refill Capacities” before this procedure is started in order to determine the following: NOTICE Caterpillar oil filters are built to Caterpillar speci- fications.
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. The type of oil pan The refill capacity for engine oil Table 20 1. Remove the oil filter with a 1U-8760 Chain Wrench. 2. Cut the oil filter open with a 175-7546 Oil Filter Cutter Gp. Break apart the pleats and inspect the oil filter for metal debris. An excessive amount of metal debris in the oil filter may indicate early wear or a pending failure. (1) Choose the interval that occurs first.
Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the oil filter element. Ferrous metals may indicate wear on the steel and cast iron parts of the engine. Drain the Engine Oil NOTICE Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, test- ing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any com- ponent containing fluids. Nonferrous metals may indicate wear on the aluminum parts, brass parts, or bronze parts of the engine. Parts that may be affected include the following items:
main bearings, rod bearings, turbocharger bearings, and cylinder heads. Due to normal wear and friction, it is not uncommon to find small amounts of debris in the oil filter. Consult your Cat dealer in order to arrange for a further analysis if an excessive amount of debris is found in the oil filter. 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. After the engine has been run at the normal operating temperature, stop the engine.
Use one of the following methods to drain the engine crankcase oil: If the engine is equipped with a drain valve, turn the drain valve knob counterclockwise in order to drain the oil. After the oil has drained, turn the drain valve knob clockwise in order to close the drain valve.
