Engine Oil and Filter - Change
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 speci-
fications. 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 larger
waste particles from unfiltered oil entering the engine
lubricating system. Only use oil filters recommended
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.

the oil filter.
NOTICE
Do not fill the oil filters with oil before installing them.
This oil would not be filtered and could be contaminat-
ed. Contaminated oil can cause accelerated wear to
engine components.
5. Install the oil filter. Tighten the oil filter by hand
according to the instructions that are shown on
the oil filter. Do not overtighten the oil filter.
