Diesel & Heavy Equipment Technician Assistant

Diesel & Heavy Equipment Technician Assistant

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 technician to work on them.

A Closer Look

Diesel technician assistants provide everything from preventive maintenance to braking system repair. They must also be able to service basic electrical systems and perform Department of Transportation (DOT) inspections.

A diesel technician assistant’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.
