DSL 131 Diesel Technology Heavy Duty Powertrains
Lecture Hours: 2
Lab Hours: 8
Credits: 6
Explores concepts in gear transmissions, differentials and clutches involved in the application of diesel-powered vehicles. Covers fundamentals of heavy-duty drivetrain in theory and shop practice. Prepares students to confidently work on power trains and their components and to diagnose and repair these systems in an industrial environment.
Prerequisite: DSL 120 and DSL 121 each with a grade of C or better; or consent of instructor.
Concurrent: DSL 130 .
Student Learning Outcomes:
- Disassemble, inspect, reassemble, and understand the power flow of transmissions.
- Remove, disassemble, reassemble, and install clutches.
- Repair and maintain power trains and their components.
- Diagnose failures and research the failure symptoms in service manuals.
