Engine O il 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 l
ubricating oil. The oil sampling valve is
positioned on the oil filter 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 samp
les are better when a sampling valve is
used. The location of the sampling valve allows oil
that is flowing under pressure to be obtained during
normal en
gine operation.
Obtain th
eSampleandtheAnalysis
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contac
t the skin.
In order to help obtain the most accurate analysis,
record
the following information before an oil sample
is taken:
•
The da
te of the sample
•
Engine model
•
Engine number
•
Serv
ice 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
las
t oil change
Ensure that the container for the sample is clean and
dr
y. 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
s
amples must be clean.
The sample can b
e 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 th
e existence of any nonferrous metal
particles in the oil.

NOTICE
Care must be taken to ensure that fluids are contained
during p
erformance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any c
ompartment or disassembling any compo-
nent containing fluids.
Dispos
eofallfluids 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
eng
ine 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
dra

stopped. Drain the oil pan with the oil warm. This
draining method allows the waste particles that are
sus
pended in the oil to be drained properly.
Failure to follow this recommended procedure will
ca
use the waste particles to be recirculated through
the engine lubrication system with the new oil.
Drain the Engine Lubricating Oil

ote: Ensurethatthevesselthatwillbeusedislarge
enough to collect the waste oil.
A
fter 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:
