Diesel & Heavy Equipment Technician

Diesel & Heavy Equipment Technician

Technical Diploma

What is the difference between gasoline and diesel engines? Beyond requiring a different fuel, diesel engines are quite different in design and have different needs and requirements when being serviced. Add to this that diesel engines are put to the test in hard-working vehicles like buses, large trucks, and equipment used in agriculture and construction, and it’s no surprise you need a specialized diesel technician to work on them.

A Closer Look

Diesel technicians deal with everything from routine oil changes to full engine rebuilds and HVAC systems. They must understand and work on the vehicle’s electrical system, engine, and working parts, using diagnostic computer software to identify issues.

A diesel technician’s work environment varies depending on the type of work they choose to do. Truck technicians spend most of their time working in a shop. Technicians who work on heavy equipment or agriculture equipment may spend more of their time working outdoors.

What You'll Learn

Graduates of Mid-State’s Diesel & Heavy Equipment Technician program have the knowledge and skills to confidently diagnose and repair mechanical and electrical problems in trucks, buses, construction equipment, farm equipment, and industrial machinery.

Through hands-on classroom learning and training on state-of-the-art equipment, you will learn to perform preventive maintenance and troubleshooting procedures, rebuild components, and respond to field service calls. You’ll also participate in field trips, tours, and equipment demonstrations, and you’ll get real-world experience by maintaining Mid-State’s vehicle fleet and operating onsite equipment.
