2. Remove the oil fi
ller cap and add oil, if necessary.
For the correct oil to use, see this Operation
and Maintenance Manual, “Refill Capacities and
Recommendati
ons” topic (Maintenance Section).
Do not fill the crankcase above “FULL” mark (X)
on the oil level gauge. Clean the oil filler cap.
Install the o
il filler cap.
3. Record the amount of oil that is added. For the
next oil samp
le and analysis, include the total
amount of oil that has been added since the
previous sample. This will help to provide the most
accurate oi
l analysis.

In addition to a good preventive maintenance
program, Caterpillar recommends using S·O·S oil
analysis at regularly scheduled intervals in order
to monitor the condition of the engine and the
maintenance requirements of the engine. 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, well 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 re
commends using the sampling valve
in order to obtain oil samples. The quality and the
consistency of the samples are better when the
sampling valv
e 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 samplin
g bottle includes the parts that are
needed for obtaining oil samples. Instructions are
also provided.
NOTICE
Always use a designated pump for oil sampling, and
use a separate designated pump for coolant sampling.
Using the same pump for both types of samples may
contaminate the samples that are being drawn. This
contaminate may cause a false analysis and an incor-
rect interpretation that could lead to concerns by both
dealers and customers.
If the engine is not equipped with a sampling valve,
use the 1U-5718 Vacuum Pump. The pump is
designed to accept sampling bottles. Disposable
tubing must be attached to the pump for insertion
into the sump.
For instructions, see Special Publication, PEHP6001,
“How To Take A Good Oil Sample”. Consult your

Hot oil and hot components can 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, s
uspended 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 eng
ine stopped. Drain the crankcase with the
oil warm. This draining method allows the waste
particles that are suspended in the oil to be drained
proper
ly.
Failure to follow this recommended procedure will
cause t
he waste particles to be recirculated through
the engine lubrication system with the new oil.
