Engine Mounts - Inspect
SMCS Code: 1152-040
Inspect the engine mounts for deterioration and for
proper bolt torque. Engine vibration can be caused
by the following conditions:
• Improper mounting of the engine
• Deterioration of the engine mounts
Any engine mount that shows deterioration should be
replaced. Refer to the Specifications Manual,
SENR3130, “Torque Specifications”. Refer to your
Caterpillar dealer for more information.

Engine Oil Level - Check
SMCS Code: 1348-535-FLV
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
Illustration 105 g00110310
(Y) “ADD” mark. (X) “FULL” mark.
NOTICE
Perform this maintenance with the engine stopped.
1. Maintain the oil level between “ADD” mark (Y) and
“FULL” mark (X) on oil level gauge (1). Do not fill
the crankcase above “FULL” mark (X).
NOTICE
Operating your engine when the oil level is above the
“FULL” mark could cause your crankshaft to dip into
the oil. The air bubbles created from the crankshaft
dipping into the oil reduces the oil's lubricating char-
acteristics and could result in the loss of power.
2. Remove the oil filler cap and add oil, if necessary.
Clean the oil filler cap. Install the oil filler cap.

Engine Oil Sample - Obtain
SMCS Code: 1000-008; 1348-554-SM; 7542-554-
SM; 7542-554-OC
In addition to a good preventive maintenance
program, Caterpillar recommends using S·O·S oil
analysis at regularly scheduled intervals. S·O·S oil
analysis provides infrared analysis, which is required
for determining nitration and oxidation levels.
Obtain the Sample and the
Analysis
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
Before you take the oil sample, complete the Label,
PEEP5031 for identification of the sample. In order to
help obtain the most accurate analysis, provide the
following information:
• Engine model
• Service hours on the engine
• The number of hours that have accumulated since
the last oil change
• The amount of oil that has been added since the
last oil change
To ensure that the sample is representative of the oil
in the crankcase, obtain a warm, mixed oil sample.
To avoid contamination of the oil samples, the tools
and the supplies that are used for obtaining oil
samples must be clean.
Caterpillar recommends using the sampling valve in
order to obtain oil samples. The quality and the
consistency of the samples are better when the
sampling valve is used. The location of the sampling
valve allows oil that is flowing under pressure to be
obtained during normal engine operation.
The 169-8373 Fluid Sampling Bottle is
recommended for use with the sampling valve. The
fluid sampling bottle includes the parts that are
needed for obtaining oil samples. Instructions are
also provided.
