Radiator - Clean
Note: Adjust t
he frequency of cleaning according to
the effects of the operating environment.
Inspect the r
adiator for these items: Damaged fins,
corrosion, dirt, grease, insects, leaves, oil, and other
debris. Clean the radiator, if necessary.
Personal i
njury can result from air pressure.
Personal injury can result without following prop-
er procedu
re. When using pressure air, wear a pro-
tective face shield and protective c lothing.
Maximum a
ir pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.
Pressur
ized air is the preferred method for removing
loose debris. Direct the air in the opposite direction
to the fan's air flow. Hold the nozzle approximately
6mm(0.2
5 inch) away from the radiator fins. Slowly
move the air nozzle in a direction that is parallel with
the radiator tube assembly. This will remove debris
that is
between the tubes.
Pressurized water may also be used for cleaning.
The max
imum water pressure for cleaning purposes
must be less than 275 kPa (40 psi). Use pressurized
water in order to soften mud. Clean the core from
both s
ides.
Use a degreaser and steam for removal of oil and
grea
se. Clean both sides of the core. Wash the core
with detergent and hot water. Thoroughly rinse the
core with clean water.
After cleaning the radiator, start the engine. Run the
engine. This will help in the removal of debris and
the
drying of the core. Stop the engine. Use a light
bulb behind the core in order to inspect the core for
cleanliness. Repeat the cleaning, if necessary.
Inspect the fins for damage. Bent fins may be opened
with a “comb”. Inspect these items for good condition:
We
lds, mounting brackets, air lines, connections,
clamps, a nd seals. Make repairs, if necessary.

Severe S ervice Application -
Check
Severe service is the application of an engine that
exceeds the current published standards for that
engine. Per
kins maintains standards for the following
engine parameters:
•
Performanc
e such as power range, speed range,
and fuel consumption
•
Fuel quali
ty
•
Operational Altitude
•
Maintenance intervals
•
Oil selec
tion and maintenance
•
Coolant type and maintenance
•
Environmental qualities
•
Install
ation
•
The temperature of the fluid in the engine
Refer to the standards for the engine or consult your
Perkins dealer or your Perkins distributor in order to
determ
ine if the engine is operating within the defined
parameters.
Sever
e service operation can accelerate component
wear. Engines that operate under severe conditions
may need more frequent maintenance intervals in
order
to ensure maximum reliability and retention of
full service life.
Due t
o individual applications, it is not possible
to identify all of the factors which can contribute
to severe service operation. Consult your Perkins
deal
er 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
app
lication.
