Abstract: A labyrinth-guard arrangement for a joint between a compactor wheel and a machine that protects against intrusion of wire wrap into a central cavity of the wheel is disclosed. The labyrinth-guard is formed by a cooperation between a first flange connected to an inner cylindrical portion of the wheel, and a second flange connected to a guard plate. The first and second flanges, along with other surrounding components, cooperate to form the labyrinth-guard.

Abstract: A computer system is provided that may include a platform, a display device, and a processor in communication with the platform and the display device. The processor may be configured to receive a bill of materials listing elements, receive models of the elements, and receive information on the quality of the elements. The processor may also be configured to identify matches between the information and the elements by comparing the information to each of the elements. The processor may further be configured to generate visual indicators on the models based on the matches, and display the models and the visual indicators on the display device.
