Cat ® Industrial Engines power the toughest machines in the harshest environments in a wide range of applications. There is no job too big or too small for the world-class product line of industrial diesel engines from Caterpillar. As the engine is typically concealed in an enclosure, it is often difficult to determine if a machine is powered by Cat. This Industrial Engines Spotter’s Guide is to assist Cat dealers in identifying Original Equipment Manufacturer machines that may be powered by Cat industrial engines. This App will continue to be updated and will never be all-inclusive. Use the App as a starting point for developing your understanding of opportunities to provide unmatched after-sale support!
