ABSTRACT:
An apparatus and method for connecting a rotatable hub to a drive shaft is disclosed in which the rotatable hub has an axial opening and a radial through opening between an outer surface of the hub and the axial opening of the hub. A rotatable shaft having an axial slot is positioned in the axial opening of the hub with the slot facing the radial through opening of the hub. One or more pins are inserted through the through opening in the hub into the slot in the shaft to insure rotation of the shaft and the hub together. The radial through opening may be covered at the outer surface of the hub to hold the pin in the through opening and in the slot.
