Engine Oil and Filter - Change
Do not drain the engine lubricating oil when the
engine 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
draining cold oil. Drain the oil pan with the engine
stopped. Drain the oil pan 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 Lubricating Oil
Note: Ensure that the vessel that will be used is large
enough to collect the waste oil.
After 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:

Typical example
• 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 oil pan, 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, replace the O
ring seal. Tighten the drain plug to 34 N·m (25 lb ft).
Replace the 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. A
horizontally installed oil filter can be drained before
removal.
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 and
turbocharger bearings.
Due to normal wear and friction, it is not
uncommon to find small amounts of debris in the
oil filter.
