Online Heavy Diesel Mechanics Classes

Online heavy diesel mechanics courses can help you get the skills to work at a repair shop, a truck fleet maintenance shop or open your own repair shop. Learn more about classes and what topics of study are included. Schools offering Diesel Mechanics degrees can also be found in these popular choices.

What Will I Learn?

Online classes for diesel engine/heavy truck mechanics cover repair and maintenance of all the systems and parts of heavy- and medium-duty trucks, including electrical and electronic systems, diesel engines, drivetrain and all other mechanical and hydraulic systems.

Most heavy-diesel mechanic courses are campus-based due to the extensive use of equipment and machinery. Distance-learning or online courses are only offered at a few private for-profit schools. Regardless of how some of your courses are delivered, you'll likely need hands-on experience to augment your courses. Classes include:

Diesel Engines

Students in a course on diesel engines learn about the components and assembly of diesel engines, from cylinders, crankshafts and turbochargers to electrical and cooling systems and electronic fuel injection. They'll also find out how to diagnose and repair engines as well as learn about preventive maintenance.

Transmissions and Drivetrains

The course focuses on the various transmissions, both manual and automatic, used in heavy trucks. Students will learn how to maintain and repair transmissions and related drivetrain components.

Brake Systems

A course in brake systems explores the various braking systems found in heavy trucks including, air, hydraulic, and other power-assisted systems. You'll discover how primary and secondary air-brake systems work together and how to troubleshoot, repair and maintain these components.

Electrical and Electronic Systems

Through this course, students will learn about electrical systems and the computer-control systems found in modern heavy trucks. Electrical and electronic systems courses also cover how to diagnose problems and make repairs or swap faulty components for new.

Hydraulic Systems

Hydraulic systems are common in heavy trucks. A course on this topic addresses how these systems operate and how to repair and maintain hydraulic lines, connectors and other related components.

How Do The Classes Work?

Online classes for heavy diesel mechanics may differ in approach. Some programs allow you to register, communicate with support staff and take quizzes online, but you'll use offline textbooks and independent exercises to work through the content at your own pace. Other programs may conduct the learning portion of the class through Internet-based videos, readings and tutorials.

Do I Need Certification?

Voluntary certification from the National Institute for Automotive Service Excellence (ASE) might be necessary or very helpful upon completion of coursework. This organization covers heavy diesel trucks as well as automobiles.
