A Rich Legacy

The roots of Cooper’s involvement with Clark after-sale support began in 1915 when the son of an American Civil War soldier started his own auto repair and motor-rebuilding business in Ponca City, Oklahoma. Clair Nickles’ auto business grew and evolved into Nickles Industrial and expanded to include large engine repairs and manufacture of replacement parts for engine brands such as Clark, Ingersoll Rand, and Worthington. The company evolved into the nation’s largest independent manufacturer of replacement parts of large stationary gas and diesel engines. The business was sold to the Cameron International Compression Group (today’s Cooper) in 2001. For 20 years, Cooper has upheld the legacy of Clair Nickles, and today, provides owners of Clark, Ingersoll Rand, and Worthington engines a complete line of after-sales support including parts, repairs, service, and technical support.
