Engine Oil and Filter - Change
SMCS Code: 1318-510
Hot oil and hot components c an cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
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
properly.
Failure to follow this recommended procedure will
cause the waste particles to be recirculated through
theenginelubricationsystemwiththenewoil.
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
Caterpillar o
il filters are built to Caterpillar speci-
fications. Use of an oil filter not recommended by
Caterpillar could result in severe engine damage to
theenginebe
arings, crankshaft, etc., as a result of
the larger waste particles from unfiltered oil entering
the engine lubricating system. Only use oil filters
recommended
by Caterpillar.
1. Remove the oil filter with a 1U-876 0 Chain
Wrench.
2. Cut the oil filter open with a 175- 7546 Oil Filter
Cutter Gp. Br
eak 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 pen
ding 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.
