A split sprocket assembly. The sprocket assembly does not require additional separate fasteners and extends substantially parallel to the axis of the drive shaft. Further, the sprocket assembly includes first and second sprocket sections having integrally formed connecting device to connect the sprocket members about the shaft. The connecting device preferably includes a projection formed on one sprocket section and a complementary recess formed on the other sprocket section. The geometry of the projection and the recess is preferably that of a dove-tail shape. The connecting device further includes a device for preventing axial movement of the sprocket sections relative to one another. In one embodiment, the sprocket assembly does not require any additional separate fasteners at all, and the preventing device includes locking members to provide a cylindrical snap fit. In an alternative embodiment, the preventing device includes fasteners extending in a direction perpendicular to a plane including the axis of the shaft and through both sprocket members.
