Diesel service technicians and mechanics inspect, repair or overhaul buses and trucks, or maintain and repair any type of diesel engine. Diesel engine maintenance and repair are 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 heavily on microprocessors to maximize fuel efficiency and minimize harmful emissions. In most shops, workers often use handheld or laptop computers to diagnose problems and adjust engine functions.
Diesel service technicians may have varied job duties:
Consult with customers and read work orders to 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 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 they run smoothly.
