MEC3190 Damage Repair 2

Advanced · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students examine methods used to complete a collision repair involving unibody parts replacement and frame correction.
Prerequisite: MEC3180: Damage Repair 1
Parameters: Access to hydraulic push/pull equipment, Gas Metal Arc Welding (GMAW) and cutting equipment, basic auto body tools and related resources. Note: The students must have access to instruction from an individual with journeyperson qualifications if they are involved in customer work.
Supporting courses: MEC2150: Suspension Systems MEC2160: Steering Systems MEC2170: Metal Repair & Finishing MEC2190: Surface Preparation 2

Outcomes The student will:

1 demonstrate established safe work procedures
- 1.1 demonstrate knowledge of and follow laboratory safety procedures
- 1.2 demonstrate safety procedures required in the use of hydraulic jacks, GMAW welding and oxyacetylene and/or plasma arc cutting equipment
- 1.3 list the safety implications of collision damage causing suspension misalignment, including legal implications
2 describe construction features and materials used in vehicle bodies and methods of repair
- 2.1 identify and describe three kinds of frame structures, giving the advantages and applications of each
- 2.2 define the terms high strength steel (HSS) and high strength low alloy (HSLA) steel, and explain the need for these metals in unibody construction
- 2.3 describe the bench system used by professional auto repair shops in unibody collision repair
3 identify misalignment of frame and suspension parts and components
- 3.1 describe and use measurements and measurement charts to determine the degree of misalignment
- 3.2 define the terms “twist,” “sag,” “sway” and “diamond”
- 3.3 describe measurements that will indicate each of the above conditions
4 use a bench frame-straightening system and related measurements to straighten/align a component
- 4.1 use a bench, or equivalent, frame-straightening system to correct alignment
- 4.2 align and fabricate damaged parts
5 correct frame/body alignment involving replacement of unibody panels and use of hydraulic jacks and welders
- 5.1 describe the correct procedure used to repair a unibody frame that shows misalignment
- 5.2 demonstrate how to use hydraulic jacking systems in the repair of collision damage
6 explain the importance of proper frame and suspension alignment, including legal implications
- 6.1 identify three kinds of suspension systems used by automakers
- 6.2 define the terms toe-in, camber and castor, and explain how each affects car tracking and driveability
