A vibratory drive unit is modular in construction and includes a base member, a top member, a number of lower spring mounting members detachably mounted to the base member, a corresponding number of upper spring mounting members detachably mounted to the top member, a corresponding number of spring members connected between the number of upper and lower spring mounting members and means for vibrating the top member relative to the base member. The various components of the vibratory drive unit are configured provide for either clockwise or counter-clockwise operation using identical drive unit components to thereby minimize component complexity and component inventory required therefore. A vibratory bowl is further provided and includes a number of locator pins extending from a bottom surface thereof. Each of the locator pins are received within a corresponding recess defined in the top member of the vibratory drive unit and attachment is made therebetween to secure the vibratory bowl to the top member of the vibratory drive unit.
