A large number of community colleges, trade and vocational schools offer programs in diesel engine repair that last from six months to two years, leading to a certificate of completion or an associate degree. Programs may offer thirty hours per week of hands-on training with equipment or lab/classroom instruction.
Although national certification is not required for employment, many diesel engine technicians and mechanics find that it increases their ability to advance. Certification by the National Institute for Automotive Service Excellence (ASE) is the recognized industry credential for diesel service technicians. Professionals may be certified in different subfields such as master truck equipment technicians. They may also be certified in various areas of repair, such as brakes, drive-trains, electrical and electronic systems, suspension and steering, or preventive maintenance and inspection. For certification in each area, a technician must pass one or more of the ASE-administered exams and present proof of two years relevant work experience. Diesel technicians are retested every five years.
Technicians also learn through on-the-job training and require three to four years of experience to become journey-level technicians. Technicians with at least three to four years of hands-on experience will qualify as journey-level diesel technicians.
Employers often send experienced technicians to special training classes conducted by manufacturers and vendors, in which workers learn about the latest technology and repair techniques.
Most technicians work a standard forty-hour week. Technicians employed by truck and bus firms providing service around the clock may work evenings, nights, and weekends.
Technicians who work for organizations that maintain their own vehicles spend most of their time doing preventive maintenance. They inspect steering mechanisms, wheel bearings, and brake systems. After an inspection, technicians repair or replace anything that is not working properly.
Diesel service technicians use a variety of tools in their work, including power tools, such as pneumatic wrenches; machine tools, such as grinding machines and lathes to rebuild brakes; welding and flame-cutting equipment to remove and repair exhaust systems; and jacks and hoists to lift and move large parts. Diesel service technicians and mechanics also use a variety of computerized testing equipment to pinpoint and analyze malfunctions in electrical systems and engines.
Diesel technicians must be versatile to adapt to customers' needs and to new technologies. It is common for technicians to handle numerous types of repairs, working on a vehicle's electrical system one day and doing major engine repairs the next.
Diesel maintenance is becoming increasingly complex, as more electronic components are used to control the operation of an engine.
Experienced technicians employed by truck fleet dealers and independent repair shops receive a commission related to the labor cost charged to the customer, with their weekly earnings dependent upon the amount of work completed.
