Cat Certified Rebuilds

Cat® Certified Rebuild

Cat® machines are designed to provide you with years of rugged reliability and unstoppable production. But even the best equipment can get “tired,” especially after heavy use in demanding applications for an extended period of time.

A Cat Certified Rebuild performed by the experts at Patten can breathe new life into your machine and extend its lifespan. Our Cat Certified Rebuilds in Northern Illinois and Northwest Indiana incorporate the same state-of-the-art technology and innovative engineering that is included in new Cat equipment. It’s like getting brand-new equipment at a fraction of the cost.

Cat Machine Rebuild

With a Cat machine rebuild, our exceptional highly-trained rebuild technicians in Chicago will replace or recondition more than 7,000 parts and components. We’ll recondition the radiator, engine, transmission, torque converter, hydraulics and axle, enabling your machine to deliver like-new performance. We’ll reinforce the frame to improve the machine’s durability, and repaint it to enhance its appearance.

An emissions upgrade is included to ensure your machine complies with current emissions standards. Upon completion, the machine will be assigned a new product identification number. Your Cat certified machine rebuild also comes with a warranty similar to that for new equipment. The approximate cost of a rebuild is about half the price of a new machine.

Cat Power Train Rebuild

Patten also performs Cat Certified Power Train Rebuilds. During the process our technicians will replace, recondition, or remanufacture more than 3,000 critical power train parts and components encompassing the radiator, engine, transmission, torque converter, final drive and axle. You’ll also benefit from the most recent engineering updates and a warranty equivalent to that of a brand-new power train. An extended power train coverage is also available. As with a Cat machine rebuild, a power train rebuild is a cost-effective alternative to buying new.
