Abstract
A method for centering the disk of a disk stack assembly. The method includes the step of applying a torque to the disk stack and spinning the disks. Both the torque and the spinning speed are less than normal operating values. A series of radial forces may then be applied to the disk stack. The series of forces will cause the rotating disks to self center. The rotating disks are eventually spun down and a full torque is applied to the disk stack to secure the disks.
