NOTICE:
During start-up when the parts of the labyrinth oil seal establish a voluntary running clearance,
a small amount of wear is experienced as the parts are in contact. This wear produces a car-
bon filled PTFE residue, visible at the outside diameter of the seal and at the drain slot. This is
the result of the two surfaces being smoothed, similar to burnishing. A lubricant should not be
applied between the faces at installation. Once the running clearance has been established, no
further wear is experienced and no decrease in seal performance occurs as a result of the car-
bon/PTFE residue.
