You need a decent sized piece of wood passed through from the other side using a club hammer and go round evenly like opposite then 90 degrees different then opposite etc. If it's that tight when you put it back together it might not close up that last little bit, the action of tightening the spindle will do the rest. Also if it's that tight there is probably not that much wrong with it wear wise.
