Heavy Duty Mechanics / Diesel

Program Overview:

A Diesel Technician has the job of repair and maintenance of diesel engines that power many types of equipment, such as buses, construction vehicles and agricultural equipment. The Diesel Technician is responsible for repairing diesel engines and all the components that help to make the engines operate efficiently. Electronics, such as fuel regulators, emissions controls systems and timing systems are often added to original power plants, so the Diesel Technician makes use of laptop or hand-held computer units to improve efficiency. The increasing use of diesel engines in transportation vehicles creates additional demand for Diesel Technicians.

Students will learn to use precision measuring tools for detailed measuring of internal and external diesel engine components during a complete engine rebuild. Students will have the opportunity to tear down and rebuild a large diesel engine, and test their skills by starting the engine at the completion of the overhaul. Students will learn about 12/24 volt electrical systems, incorporate and use math into the electrical systems, they will learn about voltage drop, resistance, wiring, and troubleshooting. Students will learn to use power and hand tools safely. The course will also cover brakes and air brake systems on large truck applications. Students will gain experience with arc welding and how to use an oxy/acetylene torch. Steering and suspension systems will be explored along with drivetrain components including transmission and clutch repair. Preventive maintenance on trucks as well as personal vehicles will also be taught and tested on. A key component vital to modern mechanics is the ability to read and understand shop manuals. Participation in the SkillsUSA youth organization will be an integral part of this course.
