This video helps cover content related to the 2017 National Automotive Technicians Education Foundation (NATEF) Required Supplemental Tasks - Tools and Equipment:
1. Identify tools and their usage in automotive applications.
2. Identify standard and metric designation.
3. Demonstrate safe handling and use of appropriate tools.
4. Demonstrate proper cleaning, storage, and maintenance of tools and equipment.
5. Demonstrate proper use of precision measuring tools (i.e. micrometer, dial indicator, dial-caliper).

QUESTIONS FOR TEACHERS:
1. How do you speed up, or slow down, a Youtube video?
2. How much torque does a typical crush sleeve require to begin crushing?
3. Why should impact guns never be used on anything that contains a bearing?
4. Google the definition of bearing "Brinelling", then describe bearing Brinelling in your own words.
5. What is the danger of putting a pipe on the end of a ratchet handle or breaker bar handle?
6. Under what conditions should a 3/4 inch drive ratchet and socket be used?
7. What is the advertised torque multiplication ratio of the torque multiplier shown in the video?
8. What is the actual torque multiplication ratio of the torque multiplier shown in the video?
9. What is the maximum output torque of the torque multiplier shown in this video?
10. How much input torque is required to reach the maximum output torque of the torque multiplier shown in this video?
