Procedure for establishing alignment of a rotor within a stator bore including at least approximately positioning shim means within a stator core bore and thereafter placing a rotor within the bore to establish a final position of the shim means and a preferred position of the rotor relative to the bore. Shim means includes a plurality of shim elements interconnected together to form shim cluster or shim pack that includes a centering element or disc. Plurality of shim elements are substantially simultaneously moved into stator bore and rotor is thereafter placed within the bore with at least part of the shim elements disposed in an air gap between rotor and stator. After the air gap between the rotor and stator has been permanently established, the individual shim elements are substantially simultaneously removed from the air gap. With "unit bearing" motors, it is advantageous to move shims in a first axial direction; move a rotor in the same axial direction; assemble a bearing system; once again move the shim elements in the same first axial direction.
