However, the use of compressed air is preferred. The element is shown with debris. Use a 4C-5084 Filter Cutter or a 175-7546 Oil Filter Cutter to cut the filter element open. Spread apart the pleats and inspect the element for metal and for other debris.
An excessive amount of debris in the filter element can indicate a possible failure. Reference: Refer to Special Publication, SEBU0518, “Know Your Cooling System” for the complete procedure for cleaning the radiator core. If metals are found in the filter element, a magnet can be used to differentiate between ferrous metals and nonferrous metals. i01555494 Ride Control Accumulator - Check Ferrous metals can indicate wear on steel parts and on cast iron parts. Nonferrous metals can indicate wear on the aluminum parts of the engine such as main bearings, rod bearings, or turbocharger bearings. SMCS Code: 5077-535-R6 Note:
When the ride control accumulator is properly charged, the fore and aft motion of the machine is reduced by the ride control accumulator. Small amounts of debris may be found in the filter element. This could be caused by friction and by normal wear. Consult your Caterpillar dealer in order to arrange for further analysis if an excessive amount of debris is found. Special tools and equipment are required in order to test the accumulator. Reference: For more information, refer to Testing and Adjusting, SENR4932, “950f Wheel Loader and 950F Series II Wheel Loader Hydraulic System”, “Accumulator (Ride Control) - Test and Charge” or consult your Caterpillar dealer.
Using an oil filter element that is not recommended by Caterpillar can result in severe engine damage to engine bearings, to the crankshaft, and to other parts. This can result in larger particles in unfiltered oil. The particles could enter the lubricating system and the particles could cause damage.
