Girth Gear Maintenance THE LIFE LINE OF THE MILL Regular maintenance of the Girth gear is an area of the mill's drive train that can be neglected by a maintenance department, albeit quite unintentionally. This oversight can result in failure or excessive wear, or both, which causes unplanned, costly mill down time.
