Course Descriptions & Student Learning Outcomes

DISL 31 - Drive Train (4)

  • Prerequisite: DISL 20

Classroom instruction and laboratory training covering both standard (single and multiple countershaft) manual transmissions. Specifically, through the disassembly, inspection, assembly, and adjustment of transmissions, a foundation will be provided for an understanding of the operating principles, basic components, and proper rebuilding and trouble shooting methods for transmissions. Also included will be Classroom instruction and laboratory training covering the disassembly, inspection, identifi cation, and adjustment of several different models of diff erentials. Specifically, work stations will include: single reduction, two speed planetary reduction, and double reduction and interaxle diff erentials. Course exit competencies will include the ability to: disassemble and assemble; inspect parts; set bearing preload, backlash, and endplay; identify tooth contact pattern; and check gear runout and torque fasteners. All of these tasks will be performed to the required manufacturer specifications as found in the component manuals.

120 hrs. lect./lab. per term
