Engine Management and Refrigeration
We’ll set codes on the engine you’re working on; it’ll be your job to tell us what’s wrong, following a step-by-step diagnosis process that includes the use of websites for CAT, Cummins, and Detroit. Additionally, you’ll go through the process of putting a 2016 Class 6 emissions truck in regen, and explore the latest technology for diesel management from the engine, to exhaust, to diagnostics. On the refrigeration side, we’ll walk you through the full history of the modern-day refrigeration system, starting with the principles of heating and cooling, and ending with servicing and troubleshooting the refrigeration system. You’ll also have the opportunity to earn EPA 608 and EPA 609 certification when the course is complete.

Power Trains
Here’s where we’ll lay your theoretical foundation in antilock brake systems and automatic traction control systems. We start with differentials, then move through hubs, kingpins, and steering. During the course, you’ll get to overhaul an Eaton-Fuller manual transmission; pull, inspect, and measure tolerances on clutches; pull and inspect single- and double-gear reduction differentials; work on and adjust brakes; and work on computer-controlled manual transmissions.
