Mack was the first truck manufacturer to produce its own diesel engines in 1938. At Adelman’s, we are proud to carry many Mack engine models in stock and ready to go. Our Mack engines have been tested and are sold complete as manufactured for original application. As with all our engines, no exchange is needed, keep your old engine for spare parts.
