<p>A method is provided for forming a clutch drum (16) having radially disposed teeth using a punch press. A blank drum is indexed on an mandrel (110) and a die (112) on the punch press forms teeth at each position. The method avoids the creation of a wave of excess material which must be accounted for in previously known methods. Also, an improved backing plate (68) is provided for use in a powershift clutch (10) which has a relief angle for reducing the bending moment created when the backing plate is loaded and which may otherwise damage the drum.</p> |
