3. Radiator mounts that are deteriorated, worn, or
damaged must be replaced. Consult your
authorised Perkins dealer or your Perkins
distributor for further assistance.
4. If the guards were removed, install the guards.
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 consult your Perkins dealer or
your Perkins distributor for assistance.

Turbocharger - Inspect
(If Equipped)
A regular visual inspection of the turbocharger is
recommended. Any fumes from the crankcase are
filtered through the air inlet system. Therefore, by-
products from oil and from combustion can collect in
the turbocharger compressor housing. Over time, this
buildup can contribute to loss of engine power,
increased black smoke and overall loss of engine
efficiency.
If the turbocharger fails during engine operation,
damage to the turbocharger compressor wheel and/
or to the engine may occur. Damage to the
turbocharger compressor wheel can cause additional
damage to the pistons, the valves, and the cylinder
head.
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-
g06483148 tended low idle operation should not cause problems
as long as a turbocharger bearing failure has not
occured.
When 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 until the turbocharger is renewed.
