Engines
We’ll teach you the (literal) tools of the trade—then you’ll immediately put them to use to pull apart and rebuild your choice of a Cummins, CAT, or Detroit engine. Throughout the course, you’ll get familiar with troubleshooting and diagnosing, performing tune-ups on all major diesel engine brands; learn how to adjust and run light-duty and heavy-duty engines; and learn how to navigate brand-specific websites.
- Measuring pistons
- Rebuilding/repairing engines
- Performing tune-ups and overheads
- Troubleshooting
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.
- On-board vehicle networks
- Multiplexing
- Emissions and after-treatment systems
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.
- Failure analysis / troubleshooting
- Clutch / transmission repair and adjustments
- Automatic traction control systems
Fluid Power and Electrical
Get the skills you need to work on any kind of heavy equipment! We’ll cover the foundations of hydraulics; hydrostatic drive transmissions; and how to properly hook up and perform tests using flow meters and pressure gauges. You’ll learn basic DC electricity and electrical systems; the fundamentals of heavy duty Allison torque converters; and how to diagnose, troubleshoot and repair alternators and starters using freestanding engines and skid steer loaders. At the end of the course, you’ll have the opportunity to earn the Snap-On multimeter certification.
- Basic DC and electrical systems
- Hydraulic system troubleshooting and repair
- Diagnosing alternators/starters
