In an exemplary embodiment, the method includes positioning the expandable liner hanger system within a casing string, the expandable liner hanger system including a setting tool disposed within a hanger body, the setting tool including a cone mandrel defining a tapered external surface and an expansion cone defining a tapered internal surface; en- gaging the tapered external surface with the tapered internal surface; radially expanding the hanger body to engage the casing string by displacing the cone mandrel and the ex- pansion cone in a first axial direction and relative to the hanger body; displacing the cone mandrel in a second axial direction and relative to the expansion cone to disengage the tapered internal surface from the tapered external surface, thus permitting the expan- sion cone to bell radially inward from the hanger body; and extricating the expansion cone from the hanger body.
