fitting the bearing onto the shaft and axially limiting the outer ring of the bearing by a retainer attached to the shaft;
inserting the shaft, bearing, and retainer into the lower part;
fitting the upper part onto the lower part and connecting the upper part to the lower part, the bearing being received by the first sub-region and by the second sub-region;
arranging a shim ring against the outer ring;
screwing screws into threaded holes of the housing, screw heads of the screws and/or washers arranged on the screws projecting radially on the housing to limit the shim ring; and
removing the retainer and connecting a bearing cover to the housing that axially limits the shim ring and the outer ring.
