A compressor comprising a sealed chamber delimited laterally by a shell, a drive shaft housed in the shell and guided relative to the other parts of the compressor via at least one bearing provided in a bearing support fixed to the internal wall of the shell. The method comprises steps consisting in supplying a shell have, in the fixing plane of the bearing support, an oval section comprising a small axis to which the bearing support is intended to be mounted, exerting a pressure on the shell in order to elastically deform it so as to increase the length of its small axis, inserting and positioning the bearing support in the fixing plane of the latter, and ceasing to exert a pressure on the shell so that the latter tends to elastically return to its original form and grip the bearing support.
