Do not drain the oil when the engine is cold. As the oil
cools, suspended waste particles settle on the
bottom of the oil pan. The waste particles are not
removed with the draining cold oil. Drain the
crankcase with the engine stopped. Drain the
crankcase with the oil warm. This draining method
allows the waste particles that are suspended in the
oil to be drained correctly.
Failure to follow this recommended procedure will
cause the waste particles to be recirculated through
the engine lubrication system with the new oil.
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,
remove the oil drain plug in order to allow the oil to
drain. After the oil has drained, the oil drain plug
should be cleaned and installed.
Replace the Oil Filter
NOTICE
Caterpillar oil filters are built to Caterpillar specifica-
tions. Use of an oil filter not recommended by Cater-
pillar 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 recom-
mended by Caterpillar.
1. Remove the oil filter with a
1U-8760
Chain
Wrench.
Note: The following actions can be carried out as
part of the preventive maintenance program.
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.
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.
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 Caterpillar dealer in order to
arrange for a further analysis if an excessive
amount of debris is found in the oil filter.

Note: Oil cooler (1) and adapter (2) are not installed
on all engines.
3. Clean the sealing surface of the cylinder block or
the oil cooler (1).
4. Apply clean engine oil to the new oil filter seal (3).
NOTICE
Do not fill the oil filters with oil before installing them.
This oil would not be filtered and could be contami-
nated. Contaminated oil can cause accelerated wear
to engine components.
