KCTCS Course No. KCTCS Course Title DIT 110 Introduction To Diesel Engines

Introduction/Context This lesson will instruct students on how to clean and inspect threaded holes, studs, and bolts for serviceability. Knowledge of these techniques, and the skills required to correct problems associated with this task are necessary for a student to learn if they wish to compete for high paying, high skilled jobs in a Diesel/Medium-Heavy Truck repair facility. Students need to be able to perform these tasks with 100% accuracy. Incorrectly performing these tasks can lead to engine concerns, safety problems, or create customer satisfaction issues.

Content/Presentation/Demonstration Outline Instruct students that when removing or installing a component, they should carefully inspect all bolts, studs, holes, and nuts for damage to threads. Stripped, cross-threaded, nicked, rolled, and rusty threads can produce errors in the torque values. Tell students to use compressed air to remove foreign matter from holes. Let them know that obstructions lodged in holes, such as metal and liquids, can cause a bolt to bottom out and reach torque value without obtaining the required clamping force. Inform them to examine the shank of bolts and studs for signs of twisting or overtorque fracturing. Explain that they must replace defective bolts and studs. Tell them to ensure that nuts are not distorted or cracked, and replace self-locking and defective nuts. Instruct students to clean and dress threads in holes. If threads are damaged beyond use, tell them to drill and tap the hole and install an approved Helicoil. Also, let them know to use an approved stud extractor to remove broken studs and bolts.

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 should be utilized to chart 1 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.

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. 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.)
