In this diesel engine repair course, you will learn fundamentals of engine repair and operation by learning the various components that make up the internal combustion engine. You will work on diesel engines, learn all of the parts and what they do, and build the entire engine. Once you have built and torn down engines, you will move on to electrical diagnostics, fuel system tests and valve adjustments.
Hands-on Components of the Course:
Tools & Technology Used:
Tests & Final Assessments:
In this lab, you will learn the theories and principles of diesel transmissions. You will completely disassemble and learn all the parts: what they do, how to troubleshoot, diagnose and spot wear and tear. There are a lot of moving pieces in a manual transmission, and it’s critical to go back in the case in the order it came out. Students will then completely reassemble the transmission.
This course begins with a fundamental overview of brakes, including brake theory, foundation and types of brakes along with the air supply system. You will be introduced to a variety of tools used for diagnosing concerns with the brake system. This course also covers hydraulic brake systems, ABS electronic systems, automatic traction control, power assist units and high pressure brake system diagnostics. This is very important, as a full tractor trailer can weigh up to 80,000 pounds. That’s a lot of weight to stop in a short distance.
This portion of the diesel technician training program will introduce you to the diagnosis and service of wheels and tires, front hub assemblies, steering linkage, gear boxes, steering column, power steering pumps, and rear suspension systems and alignment. These trucks need to be safe on the road, so knowing how the suspension works is key.
In this course, you will have the opportunity to learn about EPA rules and regulations. You will learn about the different types of refrigerants and oils in the market today and how to handle them properly. Your coursework will also cover the different systems vehicle manufacturers use. Some vehicles can be equipped with multiple zone systems, which means the driver and occupants have their own controls.
Additionally, students will learn about the potential dangers of working with refrigerant and high system pressures and how to avoid them. You will understand how, when refrigerant flows, it changes from a gas to a liquid in order to properly diagnose. Upon completion of this course, you will have learned the technology principles of automotive heating, ventilation and air conditioning (HVAC) through diagnosis and service of HVAC systems and sub systems, refrigerant systems and electronic climate control systems.
In this course, you will learn the fundamentals of hydraulic theory, understand and interpret the schematics, symbols, and hydraulic and hydrostatic system operation, and troubleshoot and repair. You will learn the proper procedures to safely work on the systems and will build and test hydraulic systems using common hydraulic system components, and will diagnose faults in the system. Lastly, you will learn the proper inspection and maintenance procedures of hydraulic systems.
Students in this course learn the science of electrical principles and electricity and how they are related to automotive technology. The electricity in a vehicle cannot be seen, which is why it’s important to understand how it flows through a circuit and what it does.
You will learn Ohms law, and with that understanding, learn to use a digital multi-meter to read voltage, resistance and amps. Your coursework will also cover how various electrical components operate, how to read wiring diagrams and build and test circuits. You will also troubleshoot on vehicles and perform various electrical tests. The knowledge gained in this course will be built upon throughout the rest of your courses.
In this course, you will combine what you have learned about HVAC systems and in your diesel engine training courses and apply that knowledge on an industrial scale. You will learn the fundamentals of industrial refrigeration and its applications in the trucking industry. These units are used to transport perishable goods by maintaining the proper temperature to prevent spoilage, so the role of technicians skilled in this area is incredibly important. You will learn how to maintain, diagnose and repair transport refrigeration units in order to ensure they are operating properly.
In this course, you will learn how to properly perform Department of Transportation (DOT) inspections based on the Federal Motor Carrier Safety Administration (FMCSA) guidelines. These inspections are used to evaluate the vehicle and identify to ensure that it meets the Federal safety standards to be on the road. You will also learn the manufacturers’ maintenance procedures designed to reduce failures. If a truck is not on the road, it is not making money, so this is an important aspect of a diesel technician’s job.
