Farmers, commercial truck drivers and firefighters are among the many who rely on diesel-powered vehicles and mobile equipment to do their jobs. In our Diesel Medium & Heavy Truck Technology program, students learn how diesel technicians keep harvesters, truck tractors, fire trucks and other big machines rumbling the right way. They master the following skills while working with vehicles manufactured by Freightliner, Kenworth, Mack Trucks, Navistar, Peterbilt, Volvo and many others:

• Inspect suspension and steering systems; repair or replace their components
• Inspect brake systems and drivelines; repair or replace their components
• Inspect diesel engines; repair or replace their components
• Inspect air intake, exhaust and fuel systems; repair or replace their components
• Inspect cooling, electrical and electronic systems; repair or replace their components

Guided by a curriculum developed with industry input, students sharpen their skills in a program lab outfitted with fixed and mobile hydraulic vehicle lifts, a gantry crane, a computerized diagnostic system and other industry-standard equipment. Instruction begins with shop safety, proper tool use and other fundamentals before advancing to activities like performing a diesel engine tune-up or replacing a cylinder head.

Supervised by their instructor, students gain real-world experience by servicing vehicles for local fire and ambulance companies, as well as LCTI’s adult education programs. Upperclassmen are encouraged to further develop their skills by seeking internships or co-op positions with local trucking companies or dealerships.
