Oil Filter - Inspect
SMCS Code: 1308-507; 3004-507; 3067-507; 5068-507
Inspect A Used Filter for Debris
Illustration 279
The element is shown with debris.
Use a 4C-5084 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.
If metals are found in the filter element a magnet can be used
to differentiate between ferrous metals and nonferrous metals.
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.
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.
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.
