Some tailor programs to heavy equipment mechanics. These programs educate the student in the basics of analysis and diagnostic techniques, while improving communication skills. The increased use of electronics and computers makes training in the fundamentals of electronics an essential tool for new mobile heavy equipment mechanics. These programs provide a basic foundation in the components of diesel and heavy equipment technology. This also enables trainee mechanics to advance more rapidly to the journey, or experienced worker, level.
Most beginners perform routine service tasks and make minor repairs after a few months' experience.
They advance to increasingly difficult jobs as they prove their ability and competence. After they master the repair and service of diesel engines, they learn to work on related components such as brakes, transmissions, and electrical systems. Many employers send trainee mechanics to training sessions conducted by heavy equipment manufacturers. These sessions, which typically last up to 1 week, provide intensive instruction in the repair of a manufacturer's equipment. Some sessions focus on particular components found in all of the manufacturer's equipment, such as diesel engines, transmissions, axles, and electrical systems.
