Engine Oil and Filter - Change
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

Oil drain plug
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, turn
the drain valve knob counterclockwise in order to
drain the oil. After the oil has drained, turn the
drain valve knob clockwise in order to close the
drain valve.
• If the engine is not equipped with a drain valve,

remove the oil drain plug (1) in order to allow the
oil to drain. If the engine is equipped with a
shallow sump, remove the bottom oil drain plugs
from both ends of the oil pan.
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.
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 with a suitable tool.
Note: The following actions can be carried out as
part of the preventive maintenance program.
2. Cut the oil filter open with a suitable tool. Break
apart the pleats and inspect the oil filter for metal
debris. An excessive amount of metal debris in the
oil filter may indicate early wear or a pending
failure.
Use a magnet to differentiate between the ferrous
metals and the nonferrous metals that are found in
the oil filter element. Ferrous metals may indicate
wear on the steel and cast iron parts of the engine.
Nonferrous metals may indicate wear on the
aluminum parts, brass parts, or bronze parts of the
engine. Parts that may be affected include the
following items: main bearings, rod bearings,
turbocharger bearings and cylinder heads.
Due to normal wear and friction, it is not

uncommon to find small amounts of debris in the
oil filter.
