Career Growth & Opportunity
Diesel mechanic jobs can either be full- or part-time jobs and pay is either hourly or annual. Entry-level diesel mechanics typically earn $14-$17 per hour, which equates to between $29,000 and $36,000 annually for full-time workers. Mechanics with more experience have the opportunity to earn much more, as the annual salary for an experienced full-time worker can range from $36,000 to $68,000 per year.

As a diesel mechanic, your likely career path would be to start as a trainee, which typically requires a high school diploma. From there, you would move up to a diesel mechanic role and eventually look to progress toward becoming a Master Technician or Service Manager.

A Day in the Life: Diesel Mechanics

Diesel mechanics can be found mostly working in repair shops, but occasionally work for vehicle equipment dealers, trucking companies or public transit companies.

Most diesel mechanics work regular 40-hour weeks. They may work very long hours during busy periods, sometimes up to 70 hours a week. Some repair companies offer 24-hour service. Mechanics at these companies may have to work some evenings and weekends.

Mechanics can't be afraid of getting dirty! This job is also physically demanding. Those who work in larger shops often specialize in one area, such as bus engines. In smaller shops, mechanics are more likely to work on engines of all kinds.
