Warranty Information
Maintenance Recommendatio ns
Perkins Engin
es Company Limited engines are
certified by the EPA and the CARB in order to comply
with exhaust emission standards and gaseous
emission stan
dards that are prescribed by the law at
the time of manufacture.
Efficiency of
the emission control and the engine
performance depends on adherence to proper
operation and maintenance recommendations and
use of recom
mended fuels and lubricating oils.
According to recommendations, major adjustments
and repairs should be made by your authorized
Perkins dis
tributor or your authorized Perkins dealer.
Various chemical fuel additives which claim to reduce
visible sm
oke are available commercially. Although
additives have been used to solve some isolated
smoke problems in the field, additives are not
recommen
ded for general use. The engines should
be certified without smoke depressants according to
federal smoke regulations.
Take corrective steps immediately after worn parts
which may affect the emissions level are discovered
in order
to ensure the proper operation of the
emission control systems. The use of genuine
Perkins components is recommended. If the owner
uses non
-Perkins components, then the non-Perkins
components must not adversely affect the emissions
level of the engine.
For information on the use of Aftermarket Products
and Perkins Engines, refer to this Operation and
Maint
enance Manual, “Engine Description”.
Regular maintenance intervals with a special
empha
sis on the following items are necessary in
order to keep exhaust emissions within acceptable
limits for the useful life of the engine. Refer to the
Opera
tion and Maintenance Manual, “Severe Service
Application - Check” topic (Maintenance Section).
If the engine is operating under severe conditions,
adju
st the maintenance schedule accordingly.
See your authorized Perkins distributor/dealer in
order to help analyze your specific application,
oper
ating environment, and maintenance schedule
adjustments.
The
following information is an explanation of
maintenance items for emission-related components.
See the Operation and Maintenance Manual,
“Ma
intenance Interval Schedule” (Maintenance
Section) for the specific interval for the following
items.
ENGINE AFTERTR
EATMENT SYSTEM – The
Engine Aftertreatment Systems are sensitive to the
type of fuel and lubricants that is used. Also, the
engine aftert
reatment systems are sensitive to the
operating schedule. Low quality fuel, lubricants, or
fluids may cause increases in exhaust back pressure
or clogging r
esulting in loss of power. An authorized
Perkins distributor/dealer can determine if the engine
aftertreatment systems require a service.
NOx Reduction System (NRS) – The NRS is
monitored. An authorized Perkins distributor/dealer
can determi
ne if the NRS needs service.
FUEL INJECTORS – Fuel injector tips are subject to
wear as a re
sult of fuel contamination. This damage
can cause the following conditions: an increase in
fuel consumption, black smoke, misfire, and rough
running en
gine. The fuel injector should be inspected,
tested, and replaced, if necessary. Fuel injectors can
be tested by an authorized Perkins distributor/dealer .
TURBOCHARGER – Refer to this Operation and
Maintenance Manual, “Turbocharger - Inspect” for
informat
ion on inspection of the turbocharger.
ELECTRONIC ENGINE CONTROL (ECM) – The
ECM is th
e control computer of the engine. The ECM
provides power to the electronics. The ECM monitors
data that is input from the sensors of the engine.
The ECM a
cts as a governor in order to control the
speed and the power of the engine. The ECM adjusts
injection timing and fuel pressure for the best engine
perfor
mance, the best fuel economy, and the best
control of exhaust emissions.
Errat
ic behavior of the engine may indicate a need
for repair to the ECM. Your Perkins distributor/dealer
is equipped with the necessary tools, personnel, and
proce
dures in order to perform this service.
The owner is encouraged to keep adequate
main
tenance records. However, the absence of such
r
ecords will n
ot invalidate the warranty. Refer to the
Operation and Maintenance Manual, “Maintenance
Log”
(Reference Materials Section).
The owner may perform routine maintenance,
rep
airs, and other work that is outside of the warranty.
The work may be done at any repair facility. Such
work does not need to be performed at a designated
sta
tion that is determined by the warranty in order for
thewarrantytoremaininforce.
