Diesel & Heavy Equipment Repair Technology


Graduates will have the ability to diagnosis troubles and disassemble diesel engines; replace pistons, bearings, gears, valves and bushings; install ignition systems; replace steering/suspension components; replace transmissions and parts; lubricate moving parts; diagnosis problems with and replace chassis assemblies; repair undercarriages and replace and repair pneumatic or hydraulic brake systems. These skills will be taught in both classroom and lab environments. 



One of the most high demand fields we offer at NCST is the Diesel & Heavy Equipment Repair Technology program. Here students learn all aspects of diesel engine repair as well as transmissions, pneumatic and hydraulic braking systems, and suspensions. A large focus is placed on electronics and computer diagnosis. Field service repair is included as well, showing students how to service vehicles that need repaired on location.

A class A CDL is included as the companies that hire our graduates – and an industry standard – want their employees to be able to transport equipment as well as repair it at the garage. Comprehensive classroom training coupled with hands on learning provide for an experience that will set students on a path to success.
