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 in order to reduce the chance of system
contamination.
NOTICE
For any type of leak (coolant, lube, or fuel) clean up
the fluid. If leaking is observed, find the source and
correct the leak. If leaking is suspected, check the flu-
id levels more often than recommended until the leak
is found or fixed, or until the suspicion of a leak is
proved to be unwarranted.
NOTICE
Accumulated grease and/or oil on an engine is a fire
hazard. Remove the accumulated grease and oil. Re-
fer to Operation and Maintenance Manual, “Engine -
Clean” for more information.
• Ensure that the cooling system hoses are correctly
clamped and that the cooling system hoses are
tight. Check for leaks. Check the condition of all
pipes.
• Inspect the water pumps for coolant leaks.
Note:
The water pump seal is lubricated by the
coolant in the cooling system. It is normal for a small
amount of leakage to occur as the engine cools down
and the parts contract.
