Starting Motor - Inspect

Altitude – Problems can arise when the engine is
operated at altitudes that are higher than the intended
settings for that application. Necessary adjustments
should be made.

Incorrect Operating Procedures

•
Extended operation at low idle
• Frequent hot shutdowns
•
Operating at excessive loads
•
Operating at excessive speeds
• Operating outside the intended application

Incorrect Maintenance Procedures

•
Extending the maintenance intervals
•
Failure to use recommended fuel, lubricants and
coolant/antifreeze
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

A regular visual inspection of the turbocharger is
recommended. 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 quanti-
ties of oil to enter the air intake and exhaust systems.
Loss of engine lubricant can result in serious engine
damage.
Minor leakage of oil into a turbocharger under extend-
ed low idle operation should not cause problems as
long as a turbocharger bearing failure has not oc-
cured.
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.
A visual inspection of the turbocharger can minimize
unscheduled downtime. A visual inspection of the
turbocharger can also reduce the chance for potential
damage to other engine parts.
Removal and Installation
Note: The turbochargers that are supplied are
i02177969
nonserviceable.
For options regarding the removal, installation, and
replacement, consult your Perkins dealer or your
Perkins distributor. Refer to the Disassembly and
Assembly Manual, "Turbocharger - Remove and
Turbocharger - Install" for further information.
Inspecting
The compressor housing for the turbocharger must
not be removed from the turbocharger for inspection
or removed for the cleaning of the compressor.
1. Remove the pipe from the turbocharger exhaust
outlet and remove the air intake pipe to the
i02718318
turbocharger. Visually inspect the piping for the
presence of oil. Clean the interior of the pipes
in order to prevent dirt from entering during
reassembly.
2. Check for obvious heat discoloration of the
turbocharger. Check for any loose bolts or any
missing bolts. Check for damage to the oil supply
line and the oil drain line. Check for cracks in
the housing of the turbocharger. Ensure that the
compressor wheel can rotate freely.
3. Check for the presence of oil. If oil is leaking from
the back side of the compressor wheel, there is a
possibility of a failed turbocharger oil seal.
