Engine Oil Sample - Obtain
The condition of the engine lubricating oil may be
checked at regular intervals as part of a preventive
maintenance program. Perkins include an oil
sampling valve as an option. The oil sampling valve
(if equipped) is included in order to regularly sample
the engine lubricating oil. The oil sampling valve is
positioned on the oil
fi
lter head or the oil sampling
valve is positioned on the cylinder block.
Perkins recommends using a sampling valve in order
to obtain oil samples. The quality and the consistency
of the samples are better when a sampling valve is
used. The location of the sampling valve allows oil
that is
fl
owing under pressure to be obtained during
normal engine operation.
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.
In order to help obtain the most accurate analysis,
record the following information before an oil sample
is taken:
•
The date of the sample
•
Engine model
•
Engine number
•
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
Ensure that the container for the sample is clean and
dry. Also ensure that the container for the sample is
clearly labelled.
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.
The sample can be checked for the following: the
quality of the oil, the existence of any coolant in the
oil, the existence of any ferrous metal particles in
the oil, and the existence of any nonferrous metal
particles in the oil.

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
NOTICE
Care must be taken to ensure that
fl
uids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the
fl
uid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing
fl
uids.
Dispose of all
fl
uids according to local regulations and
mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Do not drain the engine lubricating oil when the
engine is cold. As the engine lubricating oil cools,
suspended waste particles settle on the bottom of
the oil pan. The waste particles are not removed with
draining cold oil. Drain the oil pan with the engine
stopped. Drain the oil pan 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
the engine lubrication system with the new oil.
Drain the Engine Lubricating Oil
Note:
Ensure that the vessel that will be used is large
enough to collect the waste 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 oil pan:
