Diesel mechanics work on a variety of diesel-powered machines and vehicles, performing maintenance and repairs. They know everything there is to know about complex engine structures and electrical components. Individuals typically specialize in working with diesel-powered passenger vehicles, boats, large trucks and buses, or heavy equipment such as tractors and cranes, so there are many different types of diesel mechanic jobs available. Private repair shops and companies that manufacture and operate diesel equipment or vehicles employ the majority of diesel mechanics.
Many diesel mechanics diagnose and repair problems with engines, electrical systems, and transmissions in diesel-powered cars and trucks. They typically work in private shops where customers may bring their cars in for routine maintenance or major repairs. Computerized diagnostic equipment is commonly used professionals to identify problems and determine which repairs or replacement parts are required. Some specialists work exclusively on diesel-powered boat engines, performing tasks that are similar to those required in other diesel mechanic jobs.
Repairing large trucks and buses necessitates a high level of specialized knowledge and skills. On city and school buses, semi trucks, locomotives, and large delivery vehicles, mechanics may perform preventative maintenance and scheduled repairs. In order to move and replace large, heavy parts, many repair jobs on such vehicles necessitate mechanics working in groups. Truck service centers, local governments, manufacturing plants, and warehouses are all common employers of large vehicle repair experts.
Some mechanics work on large, diesel-powered construction equipment, inspecting, maintaining, and repairing it. Cranes, tractors, bulldozers, and forklifts all require routine maintenance to ensure that they are safe and in good working order. Specialty repair shops, equipment manufacturing plants, and construction companies are all good places to look for diesel mechanic jobs.
Individuals must typically have at least a high school diploma and some background knowledge of engines, machines, and repair work to obtain diesel mechanic jobs in any specialty. Many aspiring mechanics enroll in six-month to two-year diesel engine repair programs at community colleges and vocational schools. These programs teach students about common parts, procedures, and safety techniques used in repair work in the classroom and on the job.
Before working independently, many new mechanics must complete an apprenticeship or work as an assistant for up to four years. They apprentice with experienced mechanics, gaining hands-on experience and performing minor repairs under supervision. A new mechanic can advance quickly in the field if he or she has demonstrated aptitude for repairs and a strong work ethic.
