Abstract
An apparatus and method for setting a gap in a hydrodynamic bearing of a disc drive spindle motor. The invention comprises placing an end of the shaft into shaft support apertures in the hub, fitting a thrust bearing counterplate into a recess defined by an annular retaining flange that is proximate the end of the shaft, and deforming the counterplate to form a gap between the end of the shaft and a surface of the counterplate.
