1. MACHINE IDENTIFICATION
- Caterpillar machines are identified by Product Identification Numbers (PIN). Some components included in a machine may be identified by Serial Numbers (S/N). Typical components that will be serialized include engines, transmissions, bulldozers, and rippers.
- The machine and engine are further identified by arrangement numbers and in some cases modification numbers. These numbers are shown on the product identification plate(s) and on the master plate in the operator’s compartment.
- Caterpillar dealers need all of these numbers to determine accurate parts identification. Effective First Quarter 2001 the Caterpillar Product Identification Number (PIN) will change from 8 to 17 characters
- . In an effort to provide uniform equipment identification, Caterpillar and other construction equipment manufacturers are moving to comply with the latest version of the product identification numbering standard.
- Non-road machine PINs are defined by ISO 10261. The new PIN format will apply to all Caterpillar machines and generator sets. The PIN plates and frame marking will display the 17 character PIN. The new format will look like the following:
Where:
- Caterpillar’s World Manufacturing Code (characters 1-3)
- Machine Descriptor (characters 4-8)
- Check Character (character 9)
- Machine Indicator Section (MIS) or Product Sequence Number (characters 10-17). These were previously referred to as the Serial Number. Machines and generator sets produced before First Quarter 2001 will maintain their 8 character PIN format. Components such as engines, transmissions, axles, etc. and work tools will continue to use an 8 character Serial Number (S/N).
