There are three types of diagnostic codes: active,
logged and event.
Most of the diagnostic codes are logged and stored in
the ECM. For additional information, refer to the
Operation and Maintenance Manual, “Engine
Diagnostics” topic (Operation Section).
Engine Cooling and Lubrication
The cooling system and lubrication system consists
of the following components:
• Gear-driven centrifugal water pump
• Water temperature regulator which regulates the
engine coolant temperature
• Gear-driven gerotor type oil pump
• Oil cooler
The engine lubricating oil is supplied by a gerotor
type oil pump. 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
engine if the oil filter element should become
plugged.
Engine efficiency, efficiency of emission controls, and
engine performance depend on adherence to proper
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to this Operation and Maintenance
Manual, “Maintenance Interval Schedule” for more
information on maintenance items.
Engine Service Life
Engine efficiency and maximum utilization of engine
performance depend on the adherence to proper
operation and maintenance recommendations. In
addition, use recommended fuels, coolants, and
lubricants. Use the Operation and Maintenance
Manual as a guide for required engine maintenance.
Expected engine 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 over time. Reduced hours of operation at full
throttle and/or operating at reduced throttle settings
result in a lower average power demand. Reduced
hours of operation will increase the length of
operating time before an engine overhaul is required.
For more information, refer to the Operation and
Maintenance Manual, “Overhaul Considerations”
topic (Maintenance Section).
Aftermarket Products and Perkins
Engines
Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or consumables
(filters, additives, catalysts,) which are made by other
manufacturers are used on Perkins products, the
Perkins warranty 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 defects are NOT covered
under the Perkins warranty.
Aftertreatment System
The aftertreatment system is approved for use by
Perkins . In order to be emission-compliant only the
approved Perkins aftertreatment system must be
used on a Perkins engine.
