Abstract
A method for setting one or more hydrodynamic bearing gaps in a disc drive spindle motor is provided. In one embodiment, a method setting one or more hydrodynamic bearing gaps in a disc drive spindle motor includes disposing a rotary member against one or more working surfaces such that substantially no gap exists therebetween and inducing creep between the rotary member and the working surfaces. The creep creates a bearing gap therebetween the rotary member and at least one of the working surfaces. The creep may be induced by thermally cycling the motor components or applying a force to a tool coupled to a member having at least one of the working surfaces disposed thereon.
