• Oil selection and maintenance
• Coolant selection and maintenance
• Environmental qualities
• Installation
Refer to the standards for the engine or consult with
your Caterpillar dealer 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 Caterpillar
dealer for the unique maintenance that is necessary
for the engine.
The operating environment, improper operating
procedures and improper maintenance procedures
can be factors which contribute to severe service
conditions.
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 inlet air reduces
engine performance.
Air Quality – 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.
Improper Operating Procedures
• Extended operation at low idle
• Frequent hot shutdowns
• Operating at excessive loads
• Operating at excessive speeds
• Operating outside the intended application
Improper Maintenance Procedures
• Extending the maintenance intervals
• Failure to use recommended fuel, lubricants and
coolant/antifreeze

Starting Motor - Inspect
SMCS Code: 1451-040; 1453-040
Caterpillar Inc. recommends a scheduled inspection
of the starting motor. If the starting motor fails, the
engine may not start in an emergency situation.
Check the starting motor for proper operation. Check
the electrical connections and clean the electrical
connections. Refer to the Service Manual for more
information on the checking procedure and for
specifications or consult your Caterpillar dealer for
assistance.

Turbocharger - Inspect
(If Equipped)
SMCS Code: 1052; 1052-040
A regular visual inspection of the turbocharger is
recommended. Any fumes from the crankcase are
filtered through the air inlet system. Therefore, by-
products from oil and from combustion can collect in
the turbocharger compressor housing. Over time, this
buildup can contribute to loss of engine power,
increased black smoke and overall loss of engine
efficiency.
If the turbocharger fails during engine operation,
damage to the turbocharger compressor wheel and/
or to the engine may occur. Damage to the
turbocharger compressor wheel can cause additional
damage to the pistons, the valves, and the cylinder
head.
