Abstract: A wheel component and a method for installing a measurement circuit in a wheel component are disclosed. The wheel component has a surface and a sunken cavity extending below the surface in the wheel component, for holding an insertable housing. The housing may hold an electronic circuit operable to measure a physical property and transmit a measured value to a receiver. The method for installing includes receiving a housing containing the measurement circuit into a sunken cavity in a surface of the wheel component and securing the housing in the sunken cavity.

Abstract: A guide wheel for a track apparatus is provided. The guide wheel includes a central hub rotatably mounted to a frame of a track apparatus. A first guide wall extends radially from the central hub and terminates at an outer edge. A second guide wall also extends radially from the central hub and terminates at an outer edge. The first and second guide walls define a circumferentially extending channel in the guide wheel. The channel in the guide wheel sequentially receives a plurality of lugs extending from the inner surface of a flexible track of the track apparatus so as to prevent lateral movement of the track.
