Engine Diagnostics
Theenginehas
built-in diagnostics in order to ensure
that the engine systems are functioning correctly. The
operator will be alerted to the condition by a “Stop or
Warning” lamp
. Under certain conditions, the engine
horsepower and the vehicle speed may be limited.
The electronic service tool may be used to display
the diagnost
ic codes.
There are three types of diagnostic codes: active,
logged, and
event.
Most of the diagnostic codes are logged and stored
in the ECM. F
or additional information, refer to
the Operation and Maintenance Manual, “Engine
Diagnostics” topic (Operation Section).
The ECM provides an electronic governor that
controls the injector output in order to maintain the
desired e
ngine rpm.
Engine Co
oling and L ubrication
The cooling system and lubrication system consists
of the fo
llowing components:
•
Gear-driven centrifugal water pump
•
Water temperature regulator which regulates the
engine coolant temperature
•
Gear-driven rotor type oil pump
•
Oil coo
ler
The engine lubricating oil is supplied by a rotor type
oil pu
mp. The engine lubricating oil is cooled and the
engine lubricating oil is filtered. The bypass valve
can provide unrestricted flow of lubrication oil to
the en
gine if the oil filter element should become
plugged.
Engi
ne efficiency, efficiency of emission controls, and
engine performance depend on adherence to proper
operation and maintenance recommendations.
Engi
ne performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to this Operation and Maintenance
Man
ual, “Maintenance Interval Schedule” for more
information on maintenance items.
Engine Service Life
En
gine efficiency and maximum utilization of engine
performance depend on the adherence to proper
operation and maintenance recommendations. In
ad
dition, use recommended fuels, coolants and
lubricants. Use the Operation and Maintenance
Manual as a guide for required engine maintenance.
Expected engin
e life is generally predicted by the
average power that is demanded. The average power
that is demanded is based on fuel consumption of
the engine ove
r a period of time. Reduced hours of
operation at full throttle and/or operating at reduced
throttle settings result in a lower average power
demand. Redu
ced hours of operation will increase
the length of operating time before an engine
overhaul is required.
Aftermarket Products and Perkins
Engines
Perkins doe
s not warrant the quality or performance
of non-Perkins fluids and filters.
When auxil
iary devices, accessories, or consumables
(filters, additives, catalysts,) which are made by other
manufacturers are used on Perkins products, the
Perkins w
arranty is not affected simply because of
such use.
However,
failures that result from the installation
or use of other manufacturers devices,
accessories, or consumables are NOT Perkins
defects
. Therefore, the de fects are NOT covered
under the Perkins warranty.
Aftertr
eatment System
The aftertreatment system is approved for use by
Perkin
s. In order to be emission-compliant only the
approved Perkins aftertreatment system must be
used on a Perkins engine.
