Operation and maintenance manual

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
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. Ensure that the application that the
engine is installed is on level ground. 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 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. 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, replace the drain plug. If
necessary replace the seal on the drain plug. Install
drain plug and tighten to 34 N·m (25 lb ft).
Replace the Oil Filter
NOTICE
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, as a result of the larger
waste particles from unfiltered oil entering the engine
lubricating system. Only use oil filters recommended
by Perkins.
1. Using a suitable tool, remove the engine oil filter.

Typical example
2. Clean sealing surface (2).
3. Apply clean engine oil to O ring seal (3) on the new
oil filter.
NOTICE
Do not fill the oil filters with oil before installing them.
This oil would not be filtered and could be contami-
nated. Contaminated oil can cause accelerated wear
to engine components or engine damage.
4. Install the engine oil filter, spin on the oil filter until
the O ring seal contacts the oil filter base. Then,
rotate the oil filter ¾ of a full turn, by hand only.
