First Claim
1. An apparatus for use with a centrifugal clutch having a drum with a threaded opening, comprising:
- an output hub having first and second ends, the first end having threads for engaging the threaded opening of the drum, the hub having a longitudinal axis;
a sprocket associated with the second end of the hub, the sprocket having a sprocket plane generally perpendicular to the longitudinal axis of the hub;
a ball bearing assembly disposed in an interior surface of the hub, the ball bearing having a bearing plane substantially aligned with the sprocket plane; and
at least one retaining member disposed on one side of the ball bearing assembly to secure the ball bearing assembly along the interior surface of the hub.

Abstract
An apparatus for use with a centrifugal clutch having a drum with a threaded opening. The apparatus includes an output hub having first and second ends, where the first end has threads for engaging the threaded opening of the drum. The hub has a longitudinal axis. The apparatus also includes a sprocket associated with the second end of the hub where the sprocket has a sprocket plane generally perpendicular to the longitudinal axis of the hub. The apparatus includes a ball bearing assembly disposed in an interior surface of the hub where the ball bearing has a bearing plane substantially aligned with the sprocket plane. The apparatus also includes at least one retaining member disposed on one side of the ball bearing assembly to secure the ball bearing assembly along the interior surface of the hub.

7. A centrifugal clutch assembly configured to be mounted along a drive shaft of a motor, the drive shaft having an exterior surface and a shoulder at one end, the assembly comprising:
-
a first spacer configured to fit about the exterior surface of the drive shaft and abut the shoulder of the drive shaft; an output hub having first and second ends, the hub having a sprocket associated with the second end, the hub further includes a ball bearing assembly disposed in an interior surface of the hub, the ball bearing assembly having an inner race configured to fit about the exterior surface of the drive shaft and abut the first spacer; a second spacer configured to fit about the exterior surface of the drive shaft and abut the inner race of the ball bearing assembly whereby the inner race is sandwiched between the first space and the second spacer; a centrifugal clutch with a drive hub configured to fit about the exterior surface of the drive shaft and abut the inner race of the ball bearing assembly; a third spacer configured to fit about the exterior surface of the drive shaft and abut the drive hub of the centrifugal clutch whereby the drive hub is sandwiched between the second and third spacers; and an attachment mechanism configured to secure the third spacer to a free end of the drive shaft; the attachment mechanism being adjustable to apply a compressive force to the third spacer, the drive hub, the second spacer, the inner race, and the first spacer so as to prevent movement along the drive shaft. - View Dependent Claims (8, 9, 10)
