HEAVY DUTY POWER TRAINS Spring Semester 2008

Great Basin College 5.5 Credit Hour

Instructor: John Cashell (775) 753-2294

PHILOSOPHY

Student and instructor are working toward common and practical goals which are discussed at the onset. Student and instructor will be actively involved in the process of learning. Guidelines for the course are specified but latitude is given to explore new ideas and concepts. Learning is a change in ones behavior; the road to change is marked by the instructor, and the student’s responsibility is to understand.

PURPOSE & COURSE GOALS

This course is designed to give individuals experience in heavy duty power trains. Individuals will learn about automatic transmissions, power shift transmissions, torque converters, clutches and drive lines. Students will gain experience in heavy-duty power trains through classroom and laboratory projects.

Students should expect to gain the following:

* Know fundamentals of automatic transmissions.

* Know fundamentals of power shift transmissions.

* Know fundamentals of clutches and drive lines.

* Demonstrate the ability to adjust a single and double disc clutch.

* Know gear ratio calculations.

* Know speed calculations.

* Demonstrate the ability to test transmission hydraulic systems.

* Demonstrate the ability to test electrical controls for transmissions.

* Know principles of planetary gear sets.

* Know power flows through transmissions.

* Demonstrate the ability to locate sources of information related to heavy duty power trains.

* Know fundamentals of failure analysis for power trains.

* Know principles of engine brakes.

EVALUATION & GRADES

Students are evaluated on their performance in lecture and lab. Half of the final grade will come from lab work and the other half from lecture. The lecture grade will consist of quizzes, tests, homework, and projects. The lab grade will require students to complete the attached lab task sheet. Lab tasks will be evaluated be the lab instructor at the completion of the lab task. Each student will receive a work sheet describing the requirement for that task. Students must demonstrate proficiency for that task before instructor signs the task sheet.

Tests & Quizzes 50%

Lab Assignments 50%

A = 90 - 100%

B = 80 - 89

C = 70 - 79

D = 60 - 69

F = 59 ------

Attendance & Drop Policy

** Students will have until the second week of this course to drop. Students wanting to drop the course must obtain the proper forms from Students Services. Students continuing past the second week will receive the letter grade they have earned which may include the grade of "F" failure. Students will not have the option of "W" withdrawal past the second week.

Students that are late for class or are going to be absent must give notification to instructor. This can be done by leaving a message at the following numbers:

Michael Jameson Office Phone #753-2294

Bret Murphy’s Office Phone # 753-2217

Chris Marshall’s Phone # 753-2175

Office Hours: 6:30 to 7am Mon-Thurs and Friday 6:30 to 9:30am

Students missing more than three days of class will automatically be dropped from the class unless emergency circumstances can be verified. See instructor for further clarification.

If you have a disability or medical condition that will require assistance, please contact me, or the counseling center in Berg Hall. If assistance is required accommodations can be arranged.
