Who is a Diesel Mechanic?
Diesel mechanics are trained to fix the engines and other systems of diesel-powered vehicles. Diesel has a slightly different combustion engine than gasoline engines. This is why special training is needed to maintain and repair these types of vehicles.
Diesel mechanics are people who are mechanically inclined, love fixing things, have a good understanding of the hands, and enjoy solving problems. The job of a mechanic is dirty work. Most of the day is spent in coveralls so that dirt, oil, and grime don’t get on clothes. Most mechanics work during the working day and serve customers in an auto garage.
Diesel Mechanics are responsible for the maintenance, repair, and inspection of heavy-duty vehicles and machinery used in transport, construction, or farming. They are also responsible for maintaining the safety and efficiency of large engines and machines. They are skilled in troubleshooting problems and can get down to work when disassembling or reassembling engines or similar parts.
They might work in the high air fixing cranes or working in fields, or repairing farm equipment. They can either work in a fleet or work as a self-employed diesel mechanic and run a shop. Some work for the government, repairing military equipment and tanks. Diesel Mechanics need to be able to repair engines and have a good understanding of fuel, brake lines, hydraulics, and electrical systems.
They conduct diagnostic tests to determine the cause of damaged parts and systems. They also repair and retrofit engines, replace worn-out components, change the hydraulic fluid, adjust and change steering breaks. They may need to disassemble or reassemble heavy machines or vehicles to replace, repair or calibrate them.
Diesel mechanics often use computerized equipment, including pneumatic wrenches and lathes, welding torches and precision gauges, screwdrivers and mallets, as well as hydraulic jerks and precision gauges. They also test drive heavy-engine vehicles before and after repairs. They use the onboard computer program to identify problems and make adjustments.
There are many types of diesel mechanic jobs. Individuals can specialize in diesel-powered passenger cars, large trucks, buses, and boats, or heavy equipment like tractors, cranes, and other diesel-powered vehicles. Private repair shops or companies that make and maintain diesel vehicles are the best places to find diesel mechanic jobs.
Diesel mechanics are skilled in diagnosing and fixing issues with diesel-powered vehicles and trucks. Most mechanics work in private shops where customers can bring their cars in for routine maintenance or major repairs. Computerized diagnostic equipment is used by professionals to diagnose problems and determine the best repairs or replacement parts. Specialists who specialize in boat engines powered by diesel can perform similar repairs as those needed for other diesel mechanic jobs.
Large trucks and buses require specialized skills and knowledge. Preventative maintenance and scheduled repairs can be performed by diesel mechanics on large vehicles, such as semi-trucks, trains, locomotives, and delivery trucks. To move or replace large, heavy components and parts, most diesel mechanics work in groups. Truck service centers, local governments, and manufacturing plants often employ large vehicle repair experts.
Large, diesel-powered equipment can be maintained and repaired by diesel mechanics. Regular maintenance is necessary for pieces of machinery such as cranes and tractors, bulldozers, and forklifts. This ensures that they are in safe working order. This field is often filled with diesel mechanics in specialty repair shops, equipment manufacturers plants, or construction companies.
A high school diploma is required for any diesel mechanic job. They also need to have some knowledge of engines, machines, and repair. Many potential diesel mechanics enroll in diesel engine repair programs at vocational schools or community colleges for six-month to two years. These programs offer students classroom and practical instruction on common parts, procedures, safety, and techniques that are involved in repair work.
Many mechanics start as assistants or apprentices. After that, they can work independently for up to four more years. They can work under the supervision of experienced mechanics and gain hands-on experience.

Qualifications
Education
Diesel mechanics often earn their high school diploma or GED. They then go on to pursue hands-on education such as an associate degree or certificate in diesel repair or service tech. Some students complete specialized training programs, which result in a certificate rather than a degree. Many students enroll in a vocational school, where they receive direct training in job-ready skills through both classroom and hands-on lessons.
Training
A vocational school education may allow diesel mechanics to work on their own. A diesel mechanic who has not completed a specialized education may have to work with an experienced mechanic for several weeks at their first job. The training period allows the diesel mechanic to learn in a real-world setting and then apply those skills on their own.
Certification
A diesel mechanic can improve their career by becoming certified. You can get a better job, be more productive at work, and earn higher wages if you hold relevant certifications. The type of diesel mechanic work that you are interested in will determine which certifications you should pursue. There are many options:
- Machinery
The National Center for Construction Education and Research (NCCER), is the best choice for a diesel mechanic who wants to repair and maintain large machinery such as cranes and bulldozers. Credentialed members have access to a wide range of resources, including education and assistance to pass the assessments.
- Automotive
The National Institute for Automotive Service Excellence is a respected national organization that offers testing certifications in a variety of focuses. The diesel engines test is composed of 65 multiple-choice questions that are administered in just 90 minutes. These questions aim to test technical knowledge directly. This test is part of the Medium/Heavy Truck grouping. A mechanic interested in broader work can test in areas such as gasoline engines, suspension, and steering, electrical/electronic, and preventative maintenance. After completing six certifications, a mechanic can earn the ASE Master Technician title.
- Nautical
The American Boat and Yacht Council (ABYC) offers certification options for mechanics who are interested in working on boats. The ABYC, like the ASE, offers a range of testing options. A diesel mechanic can earn their support system and diesel engine certifications. This certification will increase their appeal to employers. The ability to demonstrate a skill set that can cover all possible problems on a boat will increase the chances of finding work for a diesel mechanic.
- Heavy equipment certification
Only ASE certifications are required to work on heavy construction equipment. However, if your goal is to be a specialist in heavy equipment or work primarily within the construction industry, a heavy equipment operator certification may be an option. The National Center for Construction Education and Research offers certifications for operating heavy machinery such as bulldozers and cranes. This certification will improve your skills and help you be able to repair, move, and diagnose heavy machinery without the aid of an operator.
- American Boat and Yacht Council (ABYC), certification
You may prefer to work with boats or other marine vehicles. If so, you might consider an ABYC certificate in one of these areas.
- A/C Refrigeration
- ABYC Standards
- Advanced Marine Electrical
- Diesel Engines
- Gasoline engines
- Marine composites
- Marine Corrosion
- Marine Electrical
- Marine Systems
A master technician certificate is awarded to anyone who passes at least three of these tests. These certifications are valid for five years. Anyone who wants to renew their certification must complete ten hours of continuing education and pass the recertification exam.
