Kenworth: 40 Years at Assembly Plant in Ohio


Kenworth Truck Company’s assembly plant in Chillicothe, Ohio, recently celebrated its 40th anniversary of building the company’s trucks.

The first Kenworth truck rolled off the Chillicothe assembly line in March 1974, and since that date employees at Kenworth’s largest plant have assembled more than 410,000 trucks.

“Our dedicated, well-trained employees take a great deal of pride in each and every high-quality Kenworth truck that comes off the line,” says Judy McTigue, Kenworth-Chillicothe plant manager, who noted that 3,000 customers visited the plant last year.

The plant ushered in the launch of the Paccar MX engine for the Class 8 market in the U.S. and Canada in 2010, had a record capacity of 150 trucks per day in 2011, and added a state-of-the-art, robotic build cell for Kenworth’s new 2.1-meter cab introduced in conjunction with the launch of the new Kenworth T680 in 2012.

A new volumetric paint mix machine was also installed at Chillicothe for enhanced paint quality. In 2013, the plant launched the Kenworth T880 – the new flagship of the company’s vocational trucks – and began building the new 52-inch sleeper for the T680, in addition to introducing the PACCAR MX-13 into Kenworth production.

Chillicothe has earned the prestigious ISO 14001:2004 certification for effective environmental management systems established to help build Class 8 trucks in an environmentally sustainable manner.
