• 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, the oil drain plugs should be
cleaned and installed. If necessary, replace the O
ring seal. Tighten the drain plug to 34 N·m
(301 lb in).
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, and so forth. As a result of
the larger waste particles from unfiltered oil entering
the engine lubricating system. Only use oil filters rec-
ommended by Perkins.
1. Remove the oil filter with a suitable tool.
Note: The following actions can be carried out as

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.
During to normal wear small amounts of debris
may be found in the oil filter.
