Mechanics may specialize in different types of diesel equipment such as transportation equipment, heavy vehicles, passenger cars, and light trucks or boats. Depending on the facility in which they work, their major responsibilities can vary. For example, some mechanics may focus more on preventive maintenance, while others concentrate more heavily on repairs.

• Certificate: 6 months to two years
• Associate Degree: 6 months to two years

Students wishing to pursue a career as a diesel mechanic are usually only required to have a high school diploma in order to apply for jobs. However, they must have a solid background in math, physics electronics, and repair, and they should also have direct work experience. Many potential mechanics may decide to pursue formal vocational training through a certificate or associate program. These programs can take anywhere from six months to two years to complete.

Most of these programs require students to obtain at least 30 hours a week of on-site training due to the physical nature of the job. Typically, individuals who have acquired formal education in this field have the best chance of getting a well-paying job in the industry. Diesel mechanics tend to start with small, minor projects during their first job, and then slowly increase to larger, more difficult projects once they have proven themselves and their work ethic. (BLS)

There are currently no certification requirements for the diesel mechanic industry. Once students graduate from a program at a community college or vocational school, they will be prepared to work. Some individuals choose to be certified by the National Institute for Automotive Service Excellence (ASE), which is not required, but it demonstrates competence and may boost one's resume. (BLS)

According to the U.S. Department of Labor, the average hourly wage for diesel engine specialists in 2008 was approximately $19. The top 10 percent earned more than $28/hr, and the bottom 10 percent earned less than $12/hr. Many mechanics are members of unions, which provide additional employment benefits. (BLS)

The diesel mechanic industry is moving at a slower pace than the average industry right now. Despite the slow pace, it is still expected to increase an additional 6 percent throughout the decade of 2008-2018. The best job opportunities in this field will come to those who have completed formal education and training to prepare them for this position.

The reason for the growth in this industry is primarily due to the environmental changes and regulations as well as retiring mechanics. Many diesel mechanics will be needed to ensure that diesel truck engines are up to code and retrofitted with the necessary equipment. Most new jobs will be in the repair and maintenance sectors within the diesel industry. (BLS)

Aircraft and avionics equipment mechanics and service technicians repair and ensure that aircraft equipment follows safety codes. They are in charge of following regular maintenance plans, making repairs, and completing inspections. Many of these mechanics specialize in preventive maintenance, which is a vital position in the aircraft industry.

Automotive body and related repairers repair body damage on a variety of vehicles. Their daily responsibilities include removing dents, straightening bodies, and replacing parts.

Automotive service technicians and mechanics are in charge of maintaining and repairing vehicles. They work to diagnose problems, rotate tires, change oil, and perform basic maintenance. These mechanics must keep their skills up to date as technology changes and new equipment is introduced to the auto industry.

Small engine mechanics repair and maintain equipment with small engines, such as motorcycles, boats, jet skis, or chainsaws. They must know how to operate equipment specially made for these pieces of machinery.
