Typical example
(1) Air to air charge cooler
(2) Radiator
(3) Fuel cooler
The radiator comes as an assembly with the air
charge cooler and a fuel cooler. When cleaning the
radiator, the fuel cooler can also be cleaned. After
cleaning the radiator and fuel cooler, visibly check the
air charge cooler for cleanliness and damage to the
air charge cooler fins. Make repairs, if necessary.

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 correct operation. Check
the electrical connections and clean the electrical
connections. Refer to the Systems Operation, Testing
and Adjusting Manual, "Electric Starting System -
Test" for more information on the checking procedure
and for specifications or consult your Perkins dealer
or your Perkins distributor for assistance.

Turbocharger - Inspect

Hot engine components can cause injury from
burns. Before performing maintenance on the en-
gine, allow the engine and the components to
cool.
Turbocharger bearing failures can cause large quan-
tities of oil to enter the air intake and exhaust sys-
tems. Loss of engine lubricant can result in serious
engine damage.
Minor leakage of oil into a turbocharger under ex-
tended low idle operation should not cause problems
as long as a turbocharger bearing failure has not
occurred.
A turbocharger bearing failure is accompanied by a
significant engine performance loss (exhaust smoke
or engine rpm up at no load), do not continue engine
operation. The turbocharger will need to be renewed.
g06279476 A visual inspection of the turbocharger or
turbochargers can minimize unscheduled downtime.
A visual inspection of the turbocharger or
turbochargers can also reduce the chance for
potential damage to other engine parts. Do not
inspect the engine with the engine in operation.
