Abstract
A track bolt for an undercarriage system includes a head portion. The track bolt also includes a body portion extending from the head portion. The track bolt further includes a piezo ceramic sensor mounted in a counter bore provided in the track bolt. The piezo ceramic sensor measures a value of track bolt elongation such that the value of the track bolt elongation is used to calculate a clamping force in the track bolt. The track bolt includes a plug member disposed in the counter bore for sealing the piezo ceramic sensor.
