What does a Diesel Service Technician and Mechanic do?

According to the Bureau of Labor Statistics (“BLS”), the U.S. Department of Labor’s principal fact- finding agency for the federal government in the field of labor, economics, and statistics that provides data on employment and wages, Diesel Service Technicians and Mechanics (also known as diesel technicians) inspect, repair, or overhaul buses and trucks, or maintain and repair any type of diesel engine.

Duties

Diesel Service Technicians and Mechanics typically do the following:

  • Consult with customers,  read work orders, and determine work required
  • Plan work procedures, using technical charts and manuals
  • Inspect brake systems, steering mechanisms, transmissions, engines, and other parts of vehicles
  • Follow checklists to ensure that all critical parts are examined
  • Read and interpret diagnostic test results to identify mechanical problems
  • Repair or replace malfunctioning components, parts, and other mechanical or electrical equipment
  • Perform basic care and maintenance, including changing oil, checking fluid levels, and rotating tires
  • Test-drive vehicles to ensure that they run smoothly

Because of their efficiency and durability, diesel engines have become the standard in powering trucks and buses. Other heavy vehicles and mobile equipment, including bulldozers and cranes, also are powered by diesel engines, as are many commercial boats and some passenger vehicles and pickups.

Diesel technicians make major and minor engine repairs, and work on a vehicle’s electrical and exhaust systems to comply with pollution regulations.

Diesel engine maintenance and repair is becoming more complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely on microprocessors to maximize fuel efficiency and minimize harmful emissions. In most shops, workers often use hand-held or laptop computers to diagnose problems and adjust engine functions.

Diesel technicians also use a variety of power and machine tools, such as pneumatic wrenches, lathes, grinding machines, and welding equipment. Hand tools, including pliers, sockets and ratchets, and screwdrivers, are commonly used.

Employers typically provide expensive power tools and computerized equipment, but workers generally acquire their own hand tools over time.
