Diesel Technician


Work Tasks

DIESEL TECHNICIANS repair and maintain diesel engines that power transportation equipment, such as heavy trucks, buses, and locomotives. Some diesel technicians work on construction equipment, such as bulldozers, cranes, and road graders; and farm equipment, such as farm tractors and combines. A small number of technicians repair diesel-powered passenger automobiles, light trucks, or boats. In modern shops, technicians use hand-held computers to diagnose problems and adjust engine functions. Technicians must continually learn about new techniques and advanced materials.

Entry Requirements

DIESEL TECHNICIANS may qualify for jobs through on-the-job training, but completion of a formal diesel engine training program after graduation from high school is recommended. Applicants without formal training may face stiffer competition for entry-level jobs. Many community colleges and trade and vocational schools offer training programs in diesel repair. These programs, lasting six months to two years, lead to a certificate of completion or an associate degree. Voluntary certification by the National Institute for Automotive Service Excellence (ASE) is recognized as a standard of achievement for diesel technicians.
