Severe service operation can accelerate component
wear. Engines that operate under severe conditions
may need more frequent maintenance intervals to
ensure maximum reliability and retention of full
service life.
Perkins engines are unable to identify all the factors
which can contribute to severe service operation, due
to individual applications. Consult your Perkins
dealer or your Perkins distributor for the unique
maintenance that is necessary for the engine.
The operating environment, incorrect operating
procedures, and incorrect maintenance procedures
can be factors which contribute to a severe service
application.
Fuel with cleanliness levels from ISO 18 to ISO 21
will require the optional CFM (Clean Fuel Module)
equipment to achieve 500hr filter change interval.
For fuel cleanliness of ISO 21 and above a customer
supplied fuel pre-cleaner or scrubber will be required
to condition the fuel to below the ISO 18 or ISO 21
depending upon the fuel filter option selected.
Environmental Factors
Ambient temperatures
– The engine may be
exposed to extended operation in extremelycold
environments or hot environments. Valve
components can be damaged by carbon buildup if
the engine is frequently started and stopped in
verycold temperatures. Extremely hot intake air
reduces engine performance.
Quality of the air
– The engine may be exposed to
extended operation in an environment that is dirty or
dusty, unless the equipment is cleaned regularly.
Mud, dirt, and dust can encase components.
Maintenance can become very difficult. The buildup
can contain corrosive chemicals.
Buildup
– Compounds, elements, corrosive
chemicals, and salt can damage some components.
Altitude
– Problems can arise when the engine is
operated at altitudes that are higher than the
intended settings for that application. Necessary
adjustments should be made.
Incorrect Operating Procedures
• Frequent hot shutdowns
• Operating at excessive loads
• Operating at excessive speeds
• Operating outside the intended application
Incorrect Maintenance Procedures
• Extending the maintenance intervals
• Failure to use recommended fuel, lubricants, and
coolant/antifreeze

Starting
Motor
-
Inspect
Perkins
recommends
a
scheduled
inspection
of
the
starting
motor.
If
the
starting
motor
fails,
the
engine
may
not
start
in
an
emergency
situation.
Check
the
starting
motor
for
proper
operation.
Check
the
electrical
connections
and
clean
the
electrical
connections.
Refer
to
the
Service
Manual
for
more
information
on
the
checking
procedure
and
for
specifications
or
consult
your
Perkins
distributors
for
assistance.

Turbocharger
-
Inspect
Periodic
inspection
and
cleaning
are
recommended
for
the
turbochargers.
Fouling
of
the
turbine
wheels
can
contribute
to
loss
of
engine
power
and
overall
loss
of
engine
efficiency.
If
a
turbocharger
fails
during
engine
operation,
damage
to
the
turbocharger
compressor
wheel
and/
or
to
the
engine
may
occur.
Damage
to
a
turbocharger
compressor
wheel
could
allow
parts
from
the
compressor
wheel
to
enter
an
engine
cylinder.
This
debris
can
damage
the
pistons,
the
valves,
and
the
cylinder
head.
For
information
on
inspection
of
the
turbocharger,
refer
to
“Systems
Operation
Testing
and
Adjusting”Turbocharger.

Walk-Around
Inspection
A
walk-around
inspection
should
only
take
a
few
minutes.
When
the
time
is
taken
to
perform
these
checks,
costly
repairs
and
accidents
can
be
avoided.
For
maximum
engine
service
life,
make
a
thorough
inspection
of
the
engine
compartment
before
starting
the
engine.
Look
for
items
such
as
oil
leaks
or
coolant
leaks,
loose
bolts,
worn
belts,
loose
connections,
and
trash
buildup.
Make
repairs,
as
needed:
• The guards must be in the correct place. Repair
damaged guards or replace missing guards.
• Wipe all caps and plugs before the engine is
serviced to reduce the chance of system
contamination.
