Wages, Benefits and Working Conditions

Entry level – approximately $15.00 to $18.00 an hour

Experienced – $18.00 to $22.00 an hour

Top Pay Rate – $27.00 to $45.00 + an hour

Benefits may include medical, dental, vision, paid vacations and holidays, and excellent retirement plans. Standard workweek is 40 hours with most shops providing work attire.

The work is physically demanding. Health and safety laws provide for a safe workplace, and most employers have safety programs and equipment for employee education and use. Mechanics provide their own hand tools, and employers supply specialized equipment.


Careers in Diesel and Truck Mechanics

Journey-level Diesel and Truck Mechanics are highly respected technical experts in their field. They work independently to solve problems using professional judgement, and take responsibility for the safe operation of the equipment that they repair and maintain.

Diesel and Truck Mechanics also specialize in a particular field. Areas of specialization include trucks, buses, boats, ships, locomotives, construction machines and all classifications of support equipment.

On the job, Diesel and Truck Mechanics perform a range of duties including the following:

  • Diagnosing problems in mechanical, electrical and electronic systems that require the use of sophisticated computers and other diagnostic test equipment.
  • Troubleshooting electronic controls that govern engine performance and horsepower. Transmissions and brake systems are increasingly controlled by electronic systems that interface with engine function.
  • Troubleshooting steering, hydraulic and pneumatic systems as well as brakes, axles, differentials, electric motors and compressors.

Upon acquiring the skills of a journey-level mechanic there are few limitations to career prospects associated with the trade. A partial list of career choices includes Power Mechanic, Chassis Mechanic, Field Service Technician, Power-train Mechanic, Equipment Inspector, Service Writer, Foreman, Supervisor, Manager, Trainer, Welder/Fabricator, Body and Paint Repairman, and Air Conditioning/Refrigeration Technician.

Program Time Commitment and Schedule Information

  • You may start in either the Fall or Spring semester.
  • The Certificate of Completion can be earned in four semesters. Many employers consider this certificate or its equivalent to be the minimum qualification for entry-level employment as a Mechanic/Technician.
  • Students may begin with either the Truck Mechanics Chassis Systems course or the Diesel Engines course. Both courses provide lecture and lab classes.
  • Day and evening classes are offered.

Program Costs

  • Instructional fees are currently about $1000 for the 46 unit certificate program.
  • Textbooks for the Certificate of Completion program run approximately $300.
  • Tool and safety equipment for the two-year program is required and will cost a minimum of $350. These will be the same tools needed to begin your mechanics/technicians career.
  • Work clothes and sturdy work boots or shoes are required for safety.

Financial Aid for these expenses is available for qualifying students.
