DIESEL ENGINE SPECIALISTS SINCE 2011
Since 2011, Cunning Diesel has been providing industry-leading diesel engine repair, rebuilding, machining, and performance solutions across a wide range of applications. As a family-owned and operated business, we are committed to delivering exceptional workmanship, reliable service, and long-term value to every customer we serve.
​
Unlike general repair facilities, our primary focus is diesel engines. We specialize in major engine repairs, complete overhauls, in-frame and out-of-frame rebuilds, precision machining, diagnostics, and performance enhancement. Whether performing a routine valve adjustment, diagnosing a complex aftertreatment issue, or rebuilding an engine from the ground up, our team has the expertise, tooling, and experience to deliver reliable, long-lasting results.
​
At Cunning Diesel, we invest heavily in the equipment, software, and support systems required to properly service today's increasingly complex diesel engines. With dealer-level diagnostic, programming, and service capabilities for Caterpillar, Cummins, Paccar, Detroit Diesel, John Deere, and other major manufacturers, we are equipped to perform everything from advanced troubleshooting and calibrations to complete engine commissioning.
​
At many traditional dealership environments technicians may work across multiple vehicle systems, but at Cunning Diesel we are dedicated exclusively to diesel engines. Supported by OEM service information, wiring schematics, calibration files, programming tools, and software updates from the industry's leading manufacturers, our team is able to diagnose, repair, calibrate, and optimize engines with exceptional precision.
​
Some shops outsource their tuning and calibration work, but we develop, test, and support our own proprietary in-house software solutions. Our custom engine calibrations are created internally by our team, allowing us to provide application-specific tuning, faster support, and complete control over the quality and performance of every file we deliver.
​
We also maintain a select inventory of remanufactured engines for our core product lines, including CAT, Cummins, and Detroit Diesel, as well as surplus new engines available for resale across various industries. From complete engine replacements to custom rebuilds and performance upgrades, we provide practical, cost-effective options that minimize downtime and maximize return on investment.
​
At the heart of everything we do is a commitment to quality, integrity, and customer satisfaction. We take pride in building long-term relationships with our customers by delivering dependable service, expert technical support, and industry-leading diesel engine expertise and service.
