Typical filter mounting base and filter gasket
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 contami-
nated. 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” or Operation and
Maintenance Manual, “Refill Capacities”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 seconds.
2. Start the engine and run the engine at “LOW IDLE”
for 2 minutes. Perform this procedure in order to
ensure that the lubrication system has oil and that
the oil filters are filled. Inspect the oil filter for oil
leaks.
3. Stop the engine and allow the oil to drain back to
the sump for a minimum of 10 minutes.
4. Remove the oil level gauge in order to check the oil
level. Maintain the oil level between the “ADD” and
“FULL” marks on the oil level gauge.

Engine Protective Devices -
Check
SMCS Code: 7400-535
Alarms and shutoffs must function properly. Alarms
provide timely warning to the operator. Shutoffs help
to prevent damage to the engine. Determining if the
engine protective devices are in good working order
during normal operation is impossible. Malfunctions
must be simulated in order to test the engine
protective devices.
A calibration check of the engine protective devices
will ensure that the alarms and shutoffs activate at
the setpoints. Ensure that the engine protective
devices are functioning properly.
NOTICE
During testing, abnormal operating conditions must
be simulated.
The tests must be performed correctly in order to pre-
vent possible damage to the engine.
To prevent damage to the engine, only authorized
service personnel or your Cat dealer should perform
the tests.
