ABSTRACT:
In a rotary clutch for a snowmobile comprising a movable pulley flange which carries pivotally mounted flyweights operable on rotation of the clutch to effect axial displacement of the movable flange towards a fixed pulley flange, the pivot shafts for the flyweights have previously been retained in mounting lugs on the movable flange by cotter pins or the like. Improper maintenance of such clutches has on occasion led to unorthodox methods of retaining the pivot shafts, such as the use of wire instead of cotter pins, or the replacement of the pivot shaft by a nut and bolt thereby causing severe unbalance in the clutch. To obviate this problem, the pivot shafts are now designed to be retained solely by abutment means formed integrally with the bell housing which attaches to the rear side of the movable flange.
