Ball bearing motors should always be used, since oil will run out of the bearings on a sleeve bearing motor. The main gear and pinion should be maintained in proper mesh. Improper meshing of the teeth results in a jerky or vibrating motion of the kiln. Too small a clearance will cause bottoming of the main gear on the base of the pinion teeth.

Continued operation with a bad pinion bearing poses serious risks of extensive damage to the mill's critical components. The excessive friction and misalignment caused by the faulty bearing can result in premature wear of the pinion gear and the girth gear. This, in turn, can lead to costly repairs and downtime for the mill.
