Bus and Truck Mechanics and Diesel Engine Specialists

Bus and truck mechanics and diesel engine specialists keep commercial vehicles and heavy equipment running smoothly through diagnosis, repair, and preventive maintenance. They spend their days troubleshooting engine problems, replacing worn parts, and performing routine inspections on everything from city buses to delivery trucks to construction equipment. Using diagnostic computers and traditional hand tools, they test components like fuel systems, transmissions, and brake assemblies to identify issues. Much of their work involves repairing or overhauling diesel engines, which power most large commercial vehicles. They disassemble engines, examine parts for wear or damage, and rebuild them with precision.
