Course Description: This course develops the skills needed to safely diagnose, repair and maintain the systems and sub-systems specific to over-the-road diesel powered vehicles. Topics will include: Diagnosing problems in mechanical, electrical, pneumatic, and electronic systems with industry standard test equipment; Troubleshooting the sophisticated electronic controls that govern engine performance and horsepower as well as transmission and braking systems; Troubleshooting steering, hydraulic, pneumatic systems, brakes, axles, differentials, electric motors, and compressors. Students will learn industry standardized safety inspection procedures.
Objectives
Upon successful completion of this course, the student should be able to:
- Troubleshoot and perform repairs on mechanical, electrical, pneumatic, hydraulic and electronic systems.
- Use computers to diagnose equipment and research information.
- Perform preventative maintenance such as safety inspection, engine tune-ups, front-end alignments, and brake adjustments.
- Operate shop machinery and equipment including hoists, hydraulic jacks, steam cleaners, floor jacks, disassembly stands, grinders, drill presses, hydraulic presses, and bead blasters.
- Select and use precision tools such as torque wrenches, micrometers, dial indicators, tap and dies, and bore gauges.
- Analyze unique situations and make informed professional decisions.
