The quickest way would be having a CAT-Mechanic with a CAT-ET (Electronic Technician) plugging in the computer to the ECM. Then you get the S/N for your engine.

I am working on a 3406b that is not original to the truck. I have scrapped and looked all over the engine but cannot find serial number. Cat parts guys cannot find the men's room without the serial number. I need to get the seals for the injectors and sleeves. Please help.
