Abstract
A low mass, two piece planetary gear carrier having an integrated clutch housing comprises a first carrier flange and clutch housing and a second carrier flange which are secured together by a plurality of threaded fasteners extending through hollow dowels. A plurality of planet gears receive needle bearing assemblies which are, in turn, supported on pins or stub shafts. The stub shafts are retained in the carrier by transverse retaining pins received in the second carrier flange and extending into the shafts. Unitized washers are disposed between both faces of the planet gears and the flanges. The method of assembly is also a feature of the present invention.
