Diesel mechanics use a wide range of tools and equipment because of the size and complexity of diesel engines. Standard tools, such as screwdrivers, are necessities. Heavy equipment and computerized equipment are often used as well.
Diesel mechanics have not been left behind by the 21st century. Computers help them in a variety of ways. One example is a diesel engine analyzer. This sophisticated piece of equipment looks like a laptop in a briefcase. It hooks up to the engine and provides high-level technical feedback on the engine's performance. By knowing exactly what an engine is doing, a mechanic can better diagnose how to repair or maintain it.
Diesel mechanics also use heavy machinery. This is because diesel engines are themselves pieces of heavy machinery, so they require heavy equipment to work on them. One example is a pneumatic wrench, which automatically removes bolts without the hassle or grunt work of a hand wrench. Diesel mechanics also do a lot of welding to either cut things off or attach things to diesel-powered vehicles.
No diesel mechanic is complete without his basic hand tools. While machines do a lot of the work, there is still a place for a wrench, screwdriver and pair of pliers. These tools allow the diesel mechanic to work with precision in hard-to-reach places, which is something that heavy tools cannot offer. So, even though there is a wide variety of high-tech and high-power tools available to a diesel mechanic, he ultimately relies on his hand tools for tricky repairs.
