Precision production, craft, and repair workers, the second largest group of production jobs, account for 1 out of 5 jobs in the motor vehicle and equipment manufacturing industry.  These skilled workers set up, maintain, and repair equipment and assemble complex components such as engines.  Electricians service complex electrical equipment.  Plumbers and pipefitters install and repair piping, valves, pumps, and compressors.  Industrial machinery mechanics and maintenance repairers maintain machinery and equipment to prevent costly breakdowns and, when necessary, perform repairs.  Millwrights install and move machinery and heavy equipment according to the factory’s layout plans.  Vehicle and mobile equipment mechanics repair bodies, engines, and other parts of motor vehicles, industrial trucks, and other mobile heavy equipment.

Precision assemblers assemble engines and perform other assembly work requiring great precision.  Throughout the manufacturing process, inspectors, testers, and graders ensure that motor vehicles and parts meet quality standards.  They inspect raw materials, check parts for defects, check the uniformity of subassemblies, and test drive vehicles.  Machinists produce precision metal parts that are made in numbers too small to produce with automated machinery.  Tool and die makers produce tools, dies, and special guiding and holding devices used in machines.  Sheet metal workers cut, bend, and straighten sheet metal suitable for various motor vehicle parts.
