Diesel/Heavy Equipment Technologies

Program Header

Program Info

Instruction is individualized and competency based so students may progress at their own rate. Approximately 60 percent of the course is in the shop in a hands on learning environment with 40 percent in classroom instruction. Construction equipment such as dump trucks, road graders, front-end loaders, back hoes, bulldozers, and a large transport truck are utilized by students developing mechanical skills. Students will disassemble, measure, and reassemble diesel engines to factory specifications on equipment ranging from semi-trucks to bulldozers. Students will perform diagnostics test on electronically controlled diesel fuel systems, equipment and hydraulic controls using laptops or electronic scan tools. Skill development in job search techniques, resume writing and interviewing is provided.

Occupational levels of Technician Level 3, Technician Level 2, or Technician Level 1 will be assigned upon successful completion of the training program based on the student’s proficiency of the program’s competencies. Technical Levels awarded based on GPA during the courses of the program, Safety Awareness, Work attitude and Program Attendance also factor into Technical Levels assigned with the successful completion of the program.
