Refer to the standards for the engine or consult your
Perkins dealer or your Perkins distributor in order to
determine if the engine is operating within the defined
parameters.
Severe service operation can accelerate component
wear. Engines that operate under severe conditions
may need more frequent maintenance intervals in
order to ensure maximum reliability and retention of
full service life.
Due to individual applications, it is not possible to
identify all of the factors which can contribute to
severe service operation. Consult your Perkins
dealer or your Perkins distributor for the unique
maintenance that is necessary for the engine.
The operating environment, incorrect operating
procedures and incorrect maintenance procedures
can be factors which contribute to a severe service
application.
Environmental Factors
Ambient temperatures
– The engine may be
exposed to extended operation in extremely cold
environments or hot environments. Valve
components can be damaged by carbon buildup if
the engine is frequently started and stopped in very
cold temperatures. Extremely hot intake air reduces
engine performance.
Quality of the air
– The engine may be exposed to
extended operation in an environment that is dirty or
dusty, unless the equipment is cleaned regularly.
Mud, dirt and dust can encase components.
Maintenance can be very difficult. The buildup can
contain corrosive chemicals.
Buildup
– Compounds, elements, corrosive
chemicals and salt can damage some components.
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
