Your Caterpillar Serial Number (SN) is an 8 character alphanumeric code, typically starting with 3 letters and ending with 5 numbers. In early 2000 Caterpillar changed to a 17 character Product Identification Number (PIN) that conforms to the construction equipment industry standard. The PIN contains the serial number for the machine.

Every vehicle produced since 1981 has a unique vehicle identification number, or VIN for short. A VIN contains data specific to the vehicle it is attached to including the year the vehicle was manufactured. The 10th digit of every VIN represents the year the vehicle was made. Here is a simple VIN year chart to help you decode the year your vehicle was manufactured in.
The letters I (i), O (o), Q (q), U (u) and Z (z), as well as the number zero, are never used on a VIN because they can be confused with other digits. You may have noticed that some digits repeat, this is because the 10th digit of the VIN is re-used every 30 years.
Match the 10th digit of your vehicle's VIN to the VIN year table below to find out what year it was made. I hope you find this 10th digit VIN decoder chart useful. Learn more about your ATV VIN number.

Written by: Nick HarrisDates of castings can be found on engine blocks,cylinder heads final drive casings etc.
This is a guide to decipher the casting codes.
N U M E R A L K O D
0 1 2 3 4 5 6 7 8 9
N = 0 K = 7
U =1 0= 8
M= 2 D = 9
E= 3

R = 4A = 5
L = 6
If there are 6 letters on the casting it is the day,month and year that that piece was made.
Eg
U would be 1 M would be 2 (12)
Caterpillar Generator Serial Number Decoder
U would be 1, N would be 0 (10)
K would be 7,D would be 9 (79)
There are 6 letters so I would know the date is 12-10-79 or 12th Oct 1979

If it has 4 letters it would be month and year of manufacture.Hope this makes sense
