Caterpillar engines are identified with serial numbers, fuel system setting numbers, performance specifications and arrangement numbers. In some cases modification numbers are also used. These numbers are shown on the serial number plate mounted on the engine.Caterpillar dealers need all of these numbers to determine which components were included on the engine when it was assembled at the factory. This permits accurate identification of replacement part numbers.Ordering Parts
