The Cummins Engine Company

Headquartered in Columbus, Indiana, 40,000 Cummins employees design, manufacture, distribute, and service engines and related technologies, including fuel systems, controls, air handling, filtration, emission control and electrical power generation systems. Cummins Mercruiser Diesel is located in North Charleston, South Carolina.

Founded in 1919 as Cummins Engine Company, for its namesake Clessie Lyle Cummins, the fledgling firm was among the first to see the commercial potential of the engine technology invented two decades earlier by Rudolf Diesel.

Cummins opened its first foreign manufacturing facility in Shotts, Scotland, in 1956 and by the end of the 1960s, Cummins had expanded its sales and service network to 2,500 dealers in 98 countries. Today, Cummins has more than 5,000 facilities in 197 countries and territories.

In 1986, Cummins began acquisition of Onan and completed it in 1992. The Onan name continues to be used for modern versions of their traditional engine-driven generators for RV, marine, commercial mobility, home standby, and portable use.

Cummins has grown into one of the largest engine makers in both China and India, and for the past three years approximately half of the Company’s sales have been generated outside the United States.

Looking For a Hard to Find Part?

We list most parts in our database, which means you will find them when you do a search, but if you know a part is hard to find, we will probably have to look for it. Sometimes, prices have changed since we listed it in our catalog, so if there is a price change of more than $5 for a part, we will notify you. Often we have these parts in our inventory, but if not, we may need to order it in from a rare parts dealer. Again, this may increase your shipping estimate so if you get an e-mail about your part, you will need to add a day or two to the shipping time.
