General Information and Machine Identification

This opening section explains how Caterpillar machines are identified by Product Identification Numbers (PIN) and Serial Numbers (S/N). It covers the 17-character PIN format introduced in the first quarter of 2001, the structure of the numbering system (World Manufacturing Code, Machine Descriptor, Check Character, and Machine Indicator Section), and the 8-character Serial Number format still used for engines, transmissions, axles and work tools. A complete abbreviations and symbols guide is included, along with ordering information and a description of how the parts manual is organized. This is the section every parts buyer needs before ordering anything.
