SEAL 8F8861 - Caterpillar

Intended Use
This Power Generator is used to generate electrical power.Engine Description
Caterpillar C32 Generator Sets provide the following features:
Four-cycle
Direct fuel injection
Mechanical Electronic Unit Injector (MEUI)
Turbocharged
Air-To-Air Aftercooler (ATAAC)Electronic Engine Features
Caterpillar C32 engines are designed with electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine and auxiliary monitoring
Engine speed governing
Cold start strategy
Automatic air/fuel ratio control
Integrated ether start
Torque rise shaping
Automatic altitude compensation
Injection timing control
System diagnosticsFor more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Cooling and Lubrication
The cooling system consists of the following components:
Gear-driven centrifugal water pump
Water temperature regulators which regulate the engine coolant temperature
Gear-driven oil pump (gear type)
Oil coolerThe engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)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 this Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a time. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right sides of the engine are determined from the flywheel end. The number 1 cylinder is the most forward cylinder.

(1) Turbocharged AftercooledGenerator Description
This SR500 brushless generator is used with the following loads: mixed loads of motors and lights, SCR-controlled equipment, computer centers, installations of communications and petroleum drilling applications. The elimination of the brushes in the field circuit reduces maintenance. The elimination of the brushes in the field circuit increases reliability. The elimination of brushes provides a higher degree of protection in potentially hazardous atmospheres.The generator set packages can be utilized for prime power generation or standby power generation. The generator set packages can be used in land-based applications or marine applications.SR500 generators can be utilized in three-phase full-wave excitation and regulation. The generators have four poles. The generators have six, or twelve-lead configurations. The generators can produce electrical power in either 50 Hz or 60 Hz applications.There is a 12-lead, reconnectable generator that is available as an option.Spill Containment
