Engine Oil Sample - Obtain
NOTICE
Engine damage can occur if the crankcase is filled
above the "FULL" mark on the oil level gauge
(dipstick).
An overfull crankcase can cause the crankshaft to dip
into the oil. This will reduce the power that is devel-
oped and also force air bubbles into the oil. These
bubbles (foam) can cause the following problems: re-
duction of the oil's ability to lubricate, reduction of oil
pressure, inadequate cooling, oil blowing out of the
crankcase breathers and excessive oil consumption.
Excessive oil consumption will cause deposits to form
on the pistons and in the combustion chamber. De-
posits in the combustion chamber lead to the follow-
ing problems: guttering of the valves, packing of
carbon under the piston rings and wear of the cylin-
der liner.
If the oil level is above the "FULL" mark on the oil lev-
el gauge, drain some of the oil immediately.
1. Remove the oil level gauge to check engine oil
level. Maintain the oil level between the "ADD"
mark (Y) and the "FULL" mark (X) on the oil level
gauge (1). Do not fill the crankcase above "FULL"
mark (X).
2. If engine oil is required, remove oil filler cap to add
engine oil.
3. To choose the correct type of oil for this engine,
refer to this Operation and Maintenance Manual,
"Fluid Recommendations".
4. Clean the oil filler cap and install the oil filler cap.
5. Record the amount of oil that is added. For the
next oil sample and analysis, include the total
amount of oil that has been added since the
previous sample. Recording this information helps
to provide the most accurate oil analysis.
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 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 samples 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 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.
