AVTEC...Great careers for Alaska's future!
Alaska Vocational Technical Center


Welcome to the Diesel/Heavy Equipment Technology program. Normally, half the investment of a mining, construction, or logging business is in equipment. Good preventive maintenance is a priority and contributes to the success of the business.
 
The hands-on approach to AVTEC's Diesel/Heavy Equipment Technology program helps students learn how to service, maintain, and repair equipment ranging from dump trucks to bulldozers. As most equipment is powered by diesel engines, students will disassemble, measure, and reassemble engines to factory specifications. Because of the complexity of this equipment, students should have good mechanical aptitude, and strong reading and mathematics skills, and should also possess a desire to succeed.
 

Approximately 60% of the course is shop work and 40% is classroom instruction. Instruction is individualized so that students may progress at their own rate. Good reading and math skills are essential.

The nature of the training requires that students work outdoors. Warm clothing, rain gear, and proper boots are required.

Earn University of Alaska Credit While Attending AVTEC

Diesel/Heavy Equipment Technology graduates may earn up to 26 University of Alaska college credits towards the requirements of an Associate of Applied Science Diesel Technology Degree.
