Maintenance Section
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.
