KCTCS Course No. KCTCS Course Title DIT 190 Electrical/Electronic Systems</p><p>Introduction/Conte This lesson will instruct the student on how to inspect and replace alternator xt drive belts, pulleys, fans, tensioners, and mounting brackets, and adjust drive belts and check alignment. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in a Diesel Repair Facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident or create customer satisfaction issues.

Two of the more common causes are incorrect belt tension and misalignment. On vehicles without automatic tensioners, have them recheck belt tension after installing a new belt. Allowing the system to run for a while will seat the new belt, after which readjustment is required. Let them know that a loose belt will slip and fail prematurely. Explain that some alternators are shimmed fore and aft in their mounting brackets. Tell them to be sure to align the alternator-driven pulley with the engine drive pulley. Inform them that an alternator that is not properly shimmed or aligned will cause premature belt wear, as well as a possible squeaking noise while the engine is running. Instruct students that many belt systems use a spring-loaded tensioner that needs to be checked for the correct spring tension with a large wrench or with a socket and a long ratchet. Tell them alternators that still use an adjustable belt need to be adjusted manually to the correct tightness and then secured.</p><p>Applications/Practice 1 Refer to content</p><p>Evaluation and feedback Prior to Testing or Lab Work Objective 1. / Formative assessment / Instructor will observe students as they practice the procedure to assure correct procedure and safety practices are being followed. A checklist will be utilized to chart student progress on the task. Questioning techniques will be utilized as necessary to demonstrate student comprehension / Adaptations and/or accommodations for special needs students will be added if required.</p><p>STUDENT ASSESSMENT: (Assess student progress with performance criteria.) Objective 1 / Summative assessment / written test questions on stated objective / adaptation and / or 1 accommodations for special needs students will be added if required</p><p>IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)</p><p>REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)</p>
