Engine Cooling and Lubrication
The cooling system consists of the following
components:
• Gear-driven centrifugal water pump
• Water temperature regulator which regulates the
engine coolant temperature
• Gear-driven oil pump (gear type)
• Oil cooler
The engine lubricating oil is supplied to the engine by
a gear-driven pump. The engine lubricating oil is
cooled and the engine lubricating oil is filtered.
Bypass valves provide unrestricted flow of lubrication
oil to the engine parts when oil viscosity is high.
Bypass valves can also provide unrestricted flow of
lubrication oil to the engine parts if the oil cooler
should become plugged or 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 the 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 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. Reduced hours of operation
will increase the length of operating time before an
engine overhaul is required.
