Engine Oil Sample - Obtain; Engine Oil And Filter - Change - Perkins 1103 Operation And Maintenance Manual

1. Maintain the oil level between the "ADD" mark (Y)
and the "FULL" mark (X) on the engine oil
dipstick. Or maintain the engine oil level between
the H and L mark. Do not over fill the crankcase.
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

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
i02202699
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.

Engine Oil and Filter - Change

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, suspended 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
engine stopped. Drain the crankcase 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 Oil
Note: Ensure that the container that will be used is
large enough to collect the waste oil.
