Diesel Technology

Award: Associate of Applied Science Degree Length: Two semesters & Two Summer Terms
Fall semester entry for full-time students

If you have good mechanical aptitude and enjoy working with large machinery, Diesel Technology may be just what you are looking for. As a student in the Diesel Technology program, you will learn the latest truck and diesel repair and diagnostic techniques using up-to-date equipment. Instruction is provided in facilities using actual components and vehicles. You will be trained in the diagnosis and repair of heavy-duty transmissions, power differentials, diesel engines, electrical systems, hydraulic systems, and diesel fuel systems. Emphasis is placed on the use of current industry trends such as bio diesel instruction and hybrid-fuel saving technology, diagnostic equipment—including the use of laptop computers to troubleshoot, technical manuals, emissions and the environment, and proper tools and equipment for the job.

Truck and diesel technicians are employed by truck dealerships, heavy equipment dealerships, truck fleet operators, construction contractors, farm implement dealerships and independent truck repair shops. One year of high school algebra is recommended.

Where will I get a job?
Diesel technicians are employed by truck dealerships, heavy equipment dealerships, truck fleet operators, construction contractors, farm implement dealerships, and independent truck repair shops. Currently, there is an ever increasing high demand in transporting green energy materials, both raw and final product, including bi-products. This has increased the need for well trained technicians to maintain trucking fleets, construction sites, small and large firms. Placement is 100% in most years. Students should have no problem finding work in this field and most are employed before graduation.

How much $ will I make?
$14.50–$16.00 an hour as a beginning wage

What kind of classes will I take?
Most of the work is hands-on time in the lab. Students will work on NCC equipment as well as trucks and equipment that are brought in by local industry—there is also about one hour of lecture each day. Much of the work in this program has become diagnostic and uses computers to assess and correct problems. Students have the option of obtaining their CDL through the Diesel program.

What’s unique about this program?
NCC has excellent equipment to use and to be worked on. Students can work independently on their own projects and will receive help as needed. Local industry also supports the program by donating parts and equipment for students use. NCC owns up-to-date equipment.
