ABSTRACT:
A method to assemble a disk drive having a spindle that includes a hub. At least one disk is placed on the hub. A clamp is fastened to the hub by a plurality of threaded fasteners. Each of the plurality of threaded fasteners is initially tightened. After initial tightening, an initial couple imbalance of the spindle is determined. After the initial couple imbalance is determined, a first selected threaded fastener of the plurality of threaded fasteners is selected and rotated by a first amount of rotation that is significantly different from a second amount of rotation of a second selected threaded fastener of the plurality of threaded fasteners. The selection and rotation of the first selected threaded fastener of the plurality of fasteners is determined based on the initial couple imbalance of the spindle.
