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.
• Inspect the engine crankcase breather pipe and oil
filler tube for damage. Ensure that the tube is
clean and free from any obstructions. Ice can
cause obstructions in adverse weather conditions.
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.
Excessive coolant leakage may indicate the need to
replace a water pump. Refer to Operation and
Maintenance Manual, “Water Pump - Inspect” for
more information. If necessary, consult your Perkins
distributor.
• Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters, and the rocker cover.
• Inspect the piping for the air intake system and the
elbows for cracks and for loose clamps. Ensure
that hoses and tubes are not contacting other
hoses, tubes, wiring harnesses, and so forth.
• Ensure that the areas around the rotating parts are
clear.
• Inspect the alternator belt and fan drive belts for
cracks, breaks, or other damage.
• Check that the fan and belts safety inspection
guards are secured in place and not damaged.
Replace if necessary. Refer to the OEM
information for any procedures that are required to
install the inspection guards.
• Inspect the fan blades for damage. Refer to the
OEM information for any procedures that are
required to install the fan.
• Inspect the wiring harness for damage.
