I'm looking at a 1995 Cat 45.   The owner has owned it for 3 yrs and doesnt know the history before him.  I called 2 Cat dealers and gave them the serial number and nothing came up, other than  a few parts he put on it.   They both told me they couldnt get prior history because of merger with Agco, and I would have to go through an Agco dealer to try and find out more?  

    Also,  on the serial number it has the second  "O"  X'd out and an "P" above it, and an "1" below it.   Neither Cat dealer knew what that meant.   The owner said it meant that it had been updated at one time? 

                              P 

Serial number     DROO142

                              1

Any suggestions on finding more info on the tractor?

Thanks!

The owner said that the number was  in front of the radiator,  stamped on the main frame.    Had to raise the hood to see it.   It does start with a 1.           SN        1DROO142

Thanks for your input

I typed in s/n 1DR00142 on CAT's warranty screen (SIMSi) and it says: "Sorry, there was no Sales Information found for Serial Number 1DR00142"

Then one paragraph down, it says: "Sorry, there is no Service Information found for Serial Number 1DR00142"

Now, I don't use this warranty system with the truck mechanic stuff I normally do, but I know that this is the area (SIMSi) that our shop clerk and warranty personnel use.

The other CAT dealer was probably looking at the same screen.

I work on truck engines only.

 Our heavy equipment shop is 3/4 mile up the street, so I am not really around heavy equipment or any Ag equipment.

I can tell you that the S/N Prefix of "1DR" is a CAT 45 Challenger machine.

It probably has something to do with the last 5 digits.

I did try 1DR0142 (only one zero), but the computer automatically changed it to 1DR00142.
