GENERAL INFORMATION
1. MACHINE IDEN
TIFICATION
Caterpillar ma
chines are identified by Product
Identification
Numbers (PIN). Some components
included in a m
achine may be identified by Serial
Numbers (S/N)
. Typical components that will be
serialized in
clude 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 iden
tification plate(s) and on the master plate in
the operator
’s compartme nt.
Caterpillar
dealers need all of these numbers to
determine a
ccurate parts identification.
Effective First Quarter 2001 the Caterpillar Product
Identification Number (PIN) changed 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:
1. Caterpillar’s World Manufacturing Code (characters 1-
3)
2. Machine Descriptor (characters 4-8)
3. Check Character (character 9)
4. 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).
2. ORDERING PAR
