However, the equipment has been very reliable, and the Lewis Center's 

 facilities n:\anagers prefer to rebuild it by, for example, rewinding motors

 facilities managers also have established a maintenance and repair 

 program designed to identify and replace components with excessive wear 

 before the equipment fails.
