Engine Oil and Filter - Change
Refer to this Operation and Maintenance Manual,
"Severe Service Application" for more information on
reducing the engine oil and filter change period. For
severe service applications the recommended oil and
filter change period is 250 hours.
If the engine is operated in severe service conditions,
Perkins recommends the use of engine oil sampling.
Refer to this Operation and Maintenance Manual,
Engine Oil sample - Obtain for more information.
If the engine is operated infrequently less than 500
hours in a 12-month period, then the engine oil and
filter change should be conducted yearly.
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:
Illustration 46
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, 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, 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 (4) with a suitable tool.

3. Apply clean engine oil to O ring seal (3) for the new
oil filter (4).
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.
