This is not uncommon with old Wico's.  The hub in the centering grommet corrodes to the shaft, so spray it down with some penatrating oil and let it soak for an hour or two.  A word of warning, this is very likely to eat up the rubber grommet, but if it is stuck to the shaft it probably isn't much good anyway.  If you want to try to save the grommet, try a silicone spray instead of penatrating oil, but it might not work as well.
