Diesel Technology II Programs

This course covers diagnosis of the hydraulic and hydrostatic system operation, and related pump and control systems. These tasks are performed on test simulators. After completing the hydraulic course, students will have the basic skills needed to safely diagnose and perform repairs on the hydraulic system.

The course introduces students 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. After completing the course, students will have the basic skills needed to perform steering and suspension repairs and wheel alignments.

This course provides students with an understanding of the drive train. By providing an overview and beginning diagnostics on the clutch system, students will learn the basics of the drive train before proceeding to the more complex manual and automated transmissions. This course includes the tasks of diagnosing and servicing clutch systems, driveline, drive axle, single and twin countershaft manual transmission, electronically automated standard transmissions, PTO, 4X4 configurations, and transfer case. After completing the course, students will have the basic skills needed to perform drive train repairs.

This course begins with a fundamental overview of brakes, including brake theory, foundation, and types of brakes along with the air supply system. Students are 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 course begins with basic engine fundamentals and manufacturer identification. The focus of the course is to remove a cylinder head and install a cylinder head, piston and liner assembly, and all components. During these procedures, students perform diagnostic tests and service the engine and components. Overviews, diagnostics, and servicing of the lubrication system, cooling system, air induction/exhaust system, starting aids, turbochargers and charge air coolers, engine brakes, EGR systems, and exhaust gas after treatment devices round out the course.

The focus of the diesel engine fuel systems and accessories course is diesel fuel systems, including mechanical system components, the electrical system and injectors; and diesel engine diagnostics. Students learn about comprehensive diagnostics and service on the following systems: low pressure common rail, hydraulic electronic unit injection (HEUI), high pressure common rail system, high pressure injection-time pressure (HPI-TP), electronic management and engine retarder. At the conclusion of the course, alternate and multi-fuel systems are introduced and students will perform diesel engine failure mode diagnostics.

This course introduces students to different inspections according to FMCSA guidelines and manufacturer specifications. Dividing the vehicle into systems and subsystems ensures proper total vehicle inspection and documentation. This course teaches standards to ensure the vehicle is properly maintained and able to pass a DOT inspection in accordance to FMCSA regulations. In addition, an overview is presented on hybrid units and the isolated batteries system.

This course provides a fundamental overview of standard refrigeration theories, including refrigerant, refrigerant oil, and the refrigeration system. It also covers regulatory policies and procedures, including EPA 608 requirements. Students will also be introduced to the multiple refrigeration system diagnostic procedures. This includes a full day of the refrigeration system brazing procedure with an instructor demonstration. The course also includes the diagnostics and servicing of auxiliary power units.
