Why diesels are good business
Anywhere loads are to be moved or work is to be done, heavy duty engines are there. Generally, these are diesel engines, which are efficient in situations where loads are heavy and steady engine speeds are the norm. These include agricultural pumps, marine propulsion, buses and shuttles, over the road trucks and motor homes. Some of the most common are those made by Cummins, Isuzu and International for use in Dodge, GM and Ford heavy duty pickups and medium-duty trucks. In motor homes, Caterpillar and Cummins engines are often seen, and for agricultural use, John Deere and Caterpillar are common brands.
Lately, there has been a surge in diesel pickup truck pulling and racing, resulting in demand for high-performance versions of some of these engines.
We talked to a number of engine builders, machine shops and performance parts manufacturers to get an idea about the heavy duty end of the engine business. In some regions, doing rebuilds for dealers is the volume part of the business, in other areas it’s agricultural and industrial diesels. At Manitowoc Motor Machining, in Manitowoc Wisconsin, the farm equipment is most common.
