Abstract
This disclosure describes, in part, systems and techniques for monitoring linkage joints of machines, such as earth-moving machines, using on-board sensors of the machines to identify linkage joints at risk of galling. The systems and techniques involve gathering sensor data and determining a galling risk score for each linkage joint. The galling risk score may then be used to alert an operator and/or maintenance system to determine when to take remedial action and/or perform maintenance while also avoiding costly downtime from galling failures.
