• 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.
Replace the Oil Filter
NOTICE
Perkins oil filters are built to Perkins specifications.
Use of an oil filter not recommended by Perkins could
result in severe engine damage to the engine bear-
ings, crankshaft, etc., as a result of the larger waste
particles from unfiltered oil entering the engine lubri-
cating 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 non-ferrous metals that are found
in the oil filter element. Ferrous metals may
indicate wear on the steel and cast iron parts of
the engine.
Non-ferrous 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. Consult your Perkins dealer or your
Perkins distributor to arrange for a further analysis
if an excessive amount of debris is found in the 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.
5. Install the oil filter. Tighten the oil filter by hand. Do
not overtighten the oil filter.
Fill the Engine Crankcase
1. Remove the oil filler cap. Refer to this Operation
and Maintenance Manual, Fluid
Recommendations for more information on
lubricant specifications.
Fill the crankcase with the correct amount of oil.
Refer to this Operation and Maintenance Manual,
Refill Capacities for more information on refill
