Engine Oil and Filter - Change

• 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.
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.

Typical example
(1) Drain plug
(2) Drain valve
After the engine has been run at the normal
operating temperature, stop the engine. Use one of
the following methods to drain the engine crankcase

oil:
• If the engine is equipped with a drain valve (2),
turn the drain valve knob counterclockwise to
drain the oil. After the oil has drained, turn the
drain valve knob clockwise to close the drain
valve.
• If the engine is not equipped with a drain valve,
remove the oil drain plug (1) to allow the oil to
drain.
After the oil has drained, the oil drain plugs should be
cleaned and installed. If necessary, renew the O ring
seal on the drain plug.
Some types of oil pans have oil drain plugs that are
on both sides of the oil pan, because of the shape of
the pan. This type of oil pan requires the engine oil to
be drained from both plugs.
Tighten the drain plug to a torque of 34 N·m
(25 lb ft).
Replace the Spin-on Oil Filter
Perkins oil filters are manufactured to Perkins specifi-
cations. Use of an oil filter that is not recommended
by Perkins could result in severe damage to the en-
gine bearings, crankshaft, etc., as a result of the larg-
er waste particles from unfiltered oil entering the
engine lubricating system. Only use oil filters recom-
mended by Perkins.
1. Remove the oil filter (5) with a suitable tool.
