Chatter Eliminated
The clutch is made very largely of steel stampings, thus insuring interchangeability of parts, exact machining, perfect balance, and great strength with minimum weight. The clutch shoes are pivoted to the driving spider by means of extra large hollow steel pins, hardened and ground, and. alKparts subject to wear are also of hardened-steel,, thereby eliminating wear and preventing'^, noise or chatter, either when the/elutch is- , engaged or disengaged.
