Perkins 2806A-E18TA Operation And Maintenance Manual page 111

SEBU9074-06
Do not operate the engine with the Instruction
Plate cover removed from the clutch. Personal in-
jury may result.
If the clutch is damaged to the point of burst fail-
ure, expelled pieces can cause personal injury to
anyone in the immediate area. Proper safeguards
must be followed to help prevent accidents.
Radiator - Clean
Note: Adjust the frequency of cleaning according to
the effects of the operating environment.
Inspect the radiator for these items: damaged fins,
corrosion, dirt, grease, insects, leaves, oil, and other
debris. Clean the radiator, if necessary.
Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a
protective face shield and protective clothing.
The maximum air pressure for cleaning purposes
must be reduced to 205 kPa (30 psi) when the air
nozzle is deadheaded.
Pressurized air is the preferred method for removing
loose debris. Direct the air in the opposite direction of
the air flow. Hold the nozzle approximately 6 mm
(0.25 inch) away from the fins. Slowly move the air
nozzle in a direction that is parallel with the tubes.
This movement will remove debris that is between
the tubes.
Pressurized water may also be used for cleaning.
The maximum water pressure for cleaning purposes
must be less than 275 kPa (40 psi). Use pressurized
water to soften mud. Clean the core from the front
and the rear.
Use a degreaser and steam for removal of oil and
grease. Clean the front and the rear of the core.
Wash the core with detergent and hot water.
Thoroughly rinse the core with clean water.
After cleaning, start the engine and bring the engine
to high idle. This procedure will help in the removal of
debris and drying of the core. Stop the engine. Use a
light bulb behind the core 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:
welds, mounting brackets, air lines, connections,
clamps, and seals. Make repairs, if necessary.
Starting Motor - Inspect
Perkins recommends a scheduled inspection of the
starting motor. If the starting motor fails, the engine
i09670468
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.
Walk-Around Inspection
Inspect the Engine for Leaks and
for Loose Connections
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.
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.
Accumulated grease and/or oil on an engine or deck
is a fire hazard. Remove this debris with steam clean-
ing or high pressure water.
