Engine Identification
Caterpillar engines are identified with serial numbers, with performance specification numbers, and with arrangement numbers. These numbers are shown on the Serial Number Plate and the Information Plate that are mounted on the engine.
Caterpillar dealers need these numbers in order to determine the components that were included with the engine. This permits accurate identification of replacement part numbers.
