Drain the Engine Oil
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.
•
If the engine is not equipped with a drain valve,
removetheoildrainpluginordertoallowtheoil
to drain. If the engine is equipped with a shallow
sump, remove the bottom oil drain plugs from both
ends of the oil pan.
After the oil has drained, the oil drain plugs should
be cleaned and installed.
Replace the Oil Filter
NOTICE
Caterpilla
roilfilters 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
recommend
ed by Caterpillar.
1. Remove the oil filter w ith 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 p
ending failure.
Use a magnet to differentiate between the ferrous
metals an
d 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.
Nonferrous metals may indicate wear on the
aluminum parts, brass parts or bronze parts of
the engi
ne. 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 filt
er. Consult your Caterpillar dealer in order
to arrange for a further analysis if an excessive
amount of debris is found in the oil filter.

3. Clean the sealing surface of the filter mounting
base. Ensure that all of the old oil filter gasket is
removed.
4. Apply clean engine oil to the new oil filter gasket.
NOTICE
Do not fill the oil filters with oil before installing them.
This oil would not be filtered and could be contaminat-
ed. Contaminated oil can cause accelerated wear to
engine components.
5. Install the oil filter. Tighten the oil filter until the
oil filter gasket contacts the base. Tighten the oil
filter by hand according to the instructions that are
shown on the oil filter. Do not overtighten the oil
filter.
Fill the Engine Crankcase
1. Remove the oil filler cap. Refer to the Operation
and Maintenance Manual, “Refill Capacities and
Recommendations” for more information.
NOTICE
If equipped with an auxiliary oil filter system or a re-
mote oil filter system, follow the OEM or filter manu-
facturer’s recommendations. Under filling or overfilling
the crankcase with oil can cause engine damage.
NOTICE
To prevent
crankshaft bearing damage, crank the en-
gine with the fuel OFF. This will fill the oil filters before
starting the engine. Do not crank the engine for more
than 30 se
conds.
2. Start the engine and run the engine at “LOW
IDLE” for two minutes. Perform this procedure in
order to e
nsure that the lubrication system has
oil and that the oil filters are fi lled. Inspect the oil
filter for oil leaks.
