DHET 110 Basic Mechanic Knowledge and Skills

15 credits

This class will introduce students to the basic concepts and skills needed in the Diesel and Heavy Equipment Industry. A brief overview will be given for each of the following quarters in the program: Frames, Running Gear and Brakes, Powertrains, Hydraulics, and Electrical and Engines. Students will engage in hands-on guided practice on customer equipment and program training aids.

Prerequisites: ABED 40 (or placement into MATH 87 or higher) and ABED 46 (or placement into ENGL 93 or higher)
