Warranty Information
Emissions Warranty Information
Efficiency of the emission control and the engine
performance depends on adherence to proper
operation and maintenance recommendations and
use of recommended fuels and lubricating oils.
According to recommendations, major adjustments
and repairs should be made by your authorized
Perkins distributor or your authorized Perkins
dealer.
Various chemical fuel additives which claim to reduce
visible smoke are available commercially. Although
additives have been used to solve some isolated
smoke problems in the field, additives are not
recommended 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
Maintenance Manual, "Engine Description".
Regular maintenance intervals with a special
emphasis 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
Operation and Maintenance Manual, "Severe Service
Application - Check" topic (Maintenance Section). If
the engine is operating under severe conditions,
adjust the maintenance schedule accordingly. See
your authorized Perkins distributor/dealer in order to
help analyze your specific application, operating
environment, and maintenance schedule
adjustments.
The following information is an explanation of
maintenance items for emission-related components.
See the Operation and Maintenance Manual,
"Maintenance Interval Schedule" (Maintenance
Section) for the specific interval for the following
items.
ENGINE AFTERTREATMENT SYSTEM – The
Engine Aftertreatment Systems are sensitive to the
type of fuel and lubricants that is used. Also, the
engine aftertreatment systems are sensitive to the
operating schedule. Low quality fuel, lubricants, or
fluids may cause increases in exhaust back pressure
or clogging resulting 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 determine if the NRS needs service.
FUEL INJECTORS – Fuel injector tips are subject to
wear as a result of fuel contamination. This damage
can cause the following conditions: an increase in
fuel consumption, black smoke, misfire and rough
running engine. 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
information on inspection of the turbocharger.
ELECTRONIC ENGINE CONTROL (ECM) – The
ECM is the 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 acts as a governor in order to control the speed
and the power of the engine.
Erratic 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
procedures in order to perform this service.
The owner is encouraged to keep adequate
maintenance records. However, the absence of such
records will not invalidate the warranty. Refer to the
Operation and Maintenance Manual, "Maintenance
Log" (Reference Materials Section).
The owner may perform routine maintenance, repairs,
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
station that is determined by the warranty in order for
the warranty to remain in force.
