When looking to buy a replacement engine for your piece of equipment, it is important to know the serial number of your current engine. This information can always be found on the data plate or engine “tag”.
Engine serial numbers are also stamped on the engine block. The engine serial number of a CAT engine is usually 8 digits long.
