(SWX:ABBN) is in advanced talks to sell its mechanical power transmission business to RBC Bearings Incorporated (NasdaqGS:ROLL), according to people familiar with the matter, as Chief Executive Officer Bjoern Rosengren swiftly overhauls the Swiss industrial giant. A deal could be reached as soon as this week and value the business, known as Dodge, at between $2.5 billion and $3 billion, said the people, who asked to not be identified because the matter isn't public.
