A common failure cause of gear driven mill systems is misalignment, which in its most severe form can cause rapid tooth fatigue and fracture. The operating temperature profile of girth gear pinions give an indication of the pinion's overall alignment with the girth gear. High differential temperatures from end to end indicate misalignment.
