Caterpillar starter can be identified only by the part number. This can be deduced from the parts manual, or alternatively, the dealer can be called. The dealer should be able to look up the part number of the Caterpillar starter using the equipment serial number. Caterpillar starter are versatile, and one type of starter has been designed to be used on a large number of engines. This should not be taken as a license to switch around starters. Only starters with the same part number can be switched around on different machines.

How does a Caterpillar Starter work? This device is simply an electrical cranking motor that turns the flywheel on an engine, while at the same time fuel is pushed into the cylinder head, and combustion occurs. This is one of the four typical ways in which an engine is started. The three (3) other ways are the gasoline engine, hydraulic cranking motor, and the use of compressed air cranking systems.

Caterpillar starter is a direct current (d.c) series or compound wire wound motor, and can operate using twelve (12) volts, twenty four (24) volts, or in some instances, thirty two (32) volts. This d.c. power is provided by lead acid batteries, and in the marine field, deep cycle lead acid batteries. These batteries are kept in a fully charged condition by the use of an alternator, which is powered via a belt or a shaft on the engine. Typically, a twenty four (24) volt charging system is the use of two twelve (12) volts lead acid batteries, connected in series.
For very large diesel engines, reduction gears are used to provide a larger turning torque on the engaging ring gears.

On Caterpillar starters, there are two positive leads from the batteries. One heavy duty battery lead connects to the main stator, and a smaller light duty positive wire connects from the instrument panel to the solenoid on the battery, via a staring switch.

The heavy duty lead to the battery is always “hot,” meaning there is live power at the terminal. The smaller wire from the starting switch, on activation, provides power to the solenoid, which rapidly moves forwards, pushing the turning starter gear to mesh with the ring gear of the engine.

Simultaneously, the movement of the solenoid forward, grounds the negative lead of the stator, energizing it. This turns the stator (either in a clockwise or an anti-clockwise rotation), which via the gears, turns the engine to initiate ignition.

After the engine has begun to start, the ignition key is released, and power is removed from the solenoid. This then returns to its inactive state via spring power, and the ground to the stator is cut. This simultaneously cuts power to the stator, and the Caterpillar Starter stops.
