7 courses with the subject DD, each shown exactly as we captured it from the college's catalog, with every element we hold. Where the wording looks broken, that is our reading of the catalog, not the college's text.
DD 101& DE-101 Preventative Maintenance 4.5/2.0
This course provides a comprehensive introduction to routine service and inspection practices for commercial diesel vehicles. Students learn how to perform fluid checks and changes, lubrication procedures, belt and hose inspections, tire and wheel service, and chassis maintenance. Emphasis is placed on identifying early signs of wear, documenting service findings, and following industry‑standard maintenance schedules to ensure optimal vehicle reliability and safety. Students will have the opportunity to test for the PA Safety Inspection Class 3 license.
Students receive in‑depth instruction on the components and operation of diesel drivetrains, including clutches, manual and automated transmissions, driveshafts, and differentials. Lab sessions provide experience with component inspection, clutch adjustment, drivetrain removal and installation, and diagnosing concerns and shifting problems. The course builds an understanding of power flow and the mechanical relationship between engine output and vehicle motion.
DD 104& DE-104 Air Brake & Braking Systems 5.0/4.0
Students explore the principles, components, and operation of heavy‑duty braking systems, with a focus on air brakes. Instruction covers compressors, air dryers, valves, chambers, slack adjusters, and anti‑lock braking systems. Hands‑on labs teach students to inspect brake assemblies, measure wear, adjust air brakes, diagnose low‑pressure conditions, and troubleshoot system faults. Safe work practices and regulatory requirements are emphasized throughout the course.
DD 106& DE-106 Suspension & Steering Systems 4.5/4.0
This course examines the structure and function of heavy‑duty suspension and steering systems. Students learn to identify and service leaf spring, air‑ride, torque arm, and other suspension configurations, along with hydraulic and mechanical steering systems. Practical activities include component inspection, steering system testing, ride‑height measurement, and alignment‑related evaluations. The course focuses on improving ride quality, stability, and vehicle handling.
This course prepares a student with the instruction and the theory based component of the Commercial Driver’s License in the form of classroom instruction. Training will included safety practices common to truck drivers, truck inspection measures, completion of required paperwork, hazmat regulations, and accident procedures. Upon completion of the course the PAGE 54
DD 206& DE-206 Commercial Vehicle HVAC Systems 3.5/2.0
Students will learn the principles of heat transfer, refrigeration, climate control operation, and HVAC system diagnostics and repair. Topics include refrigerant handling and recovery, compressor operation, air distribution systems, automatic climate control systems, and an introduction to transport refrigeration systems and their operation. Emphasis is placed on safety, environmental regulations, proper service procedures, and the use of industry-standard diagnostic equipment.
In this practical driving course, students learn to operate Class A commercial vehicles under instructor supervision. Skills covered include pre‑trip inspections, backing maneuvers, shifting techniques, trailer coupling and uncoupling, and on‑road driving in various traffic environments. The course emphasizes safe driving habits, vehicle control, spatial awareness, and successful preparation for the CDL skills exam.
