Diesel Mechanics

Diesel service technicians and mechanics inspect, repair, or overhaul buses, trucks, and anything else with a diesel engine. Diesel mechanics handle many kinds of repairs. They may work on a vehicle’s electrical system, make major engine repairs, or retrofit engines with emission control systems to comply with pollution regulations. Diesel engine maintenance is becoming increasingly complex as engines and other components use more electronic systems to control their operation. In addition to computerized diagnostic equipment, diesel mechanics use a variety of power and machine tools, such as pneumatic wrenches, lathes, grinding machines, and welding equipment. Handtools including pliers, wrenches, and screwdrivers, are also commonly used. Diesel service technicians and mechanics may work on a vehicle’s electrical system, make major engine repairs, or retrofit engines with emission control systems to comply with pollution regulations.

Part 1: Diesel Technicians may be hired as mechanics working on engines, transmissions, drive trains, electrical systems, suspension and steering, hydraulics, and air systems. They work on heavy equipment, farm equipment, and highway trucks. Diesel mechanics diagnose, repair, weld, and fine-tune the working parts of buses, trucks, construction machinery, and generators. Students will become proficient in basic shop skills, PM inspections, brake repairs, engine tune-up and rebuilding, component inspection and measuring, drive trains, suspension and steering, and electrical troubleshooting.

Part 2: Diagnostics and Repair – In this course, you will be doing real hands-on diagnostic and repair in a shop environment. You will be working on various projects that will cover the following: Steering and Suspension, Electrical, Electronics, Engines, and Drive Train. You are welcome to bring in your own project. Project needs to pertain to the Heavy-Duty Diesel Mechanics or the Diesel Mechanics industry and be approved by the instructor. You do not need to have a project vehicle to sign up for the class.
