General Serial Number Information 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. In the photo below, the PIN is 'CAT00D5GPWGB01070', and the Serial Number is 'WGB01070' -the last 8 characters of the PIN.

May 18, 2010 Hey guys Im wondering if anyone can help me out on this one. Ive got a 3406b engine serial number 4mg70859 and I'm trying to get the arrangement. Engine serial number? Post engine serial numbers and current pump location so a replacement. Caterpillar 3406 3408 3412 Series: Cat 3406 Piston.

If you are searching for a service manual for your machine, WGB01070 should be used in the ServiceManualPro.com searchbox. In the photo below, the serial number MHK03801 is for the engine only, and would not return the correct results for the complete service manual for this D5G bulldozer.

I just bought a 81 Pete 359 with a cat 3406b and the serial number plate is not on it but the number on side of block is 7XCO3316 which I believe is a Cat remanned engine. Can anyone confirm this and is there a way to find out when this engine was issued this serial number if in fact it is a reman. Block casting number is 8N92657XC is a reman prefix, but SIS is very vague on any info.

Also, the 4th is a number 0, not the letter O. 8N9265 is the pump casting number.meaning it was copied by a very early B model.
