Macey is a second-year parts technician apprentice. She is working in a used farm equipment and truck warehouse. She is responsible for reading manuals and parts books on various tractors, combines, balers, trucks, and other vehicles used on acreages and farms. When a customer phones in, Macey needs to be able to locate the appropriate manual or parts book, locate the part in the book, look the part up on her computer, inform the customer whether the warehouse has or can get the part, and determine what the part will cost.

 

Macey remembers feeling overwhelmed with all the different engines and their complex assemblies when she started her three-year apprenticeship. Now Macey finds it an adventure to locate a part she has never seen before in exploded-view diagrams.
