A clutch drum assembly comprising a clutch drum ( 21 ) and a drive means. The clutch drum ( 21 ) has an axis of rotation and includes an end wall ( 22 ). The drive means specifically a drive spline ( 1 ) or a fixed drive sprocket axially to one end of drive means, is a flange ( 5 ) with one or more radial evenly spaced minimally sized apertures ( 6 ) that have been counter sunk or counter bored to one side. Unitary axial motion of the two components is achieved via a mechanical connection between the two said components by tightly pressing metal from the outer surface of the end wall ( 22 ) clutch through each of the minimally sized apertures ( 6 ) in the drive means flange ( 5 ) against a die positioned proximate to each said aperture ( 6 ) forging the metal into the counter sunk or counter bored portion of the drive means flange ( 5 ).
