No, just roll the shade all the way down to expose the outer tube assembly..Nothing needs to be removed, including the old screw an inch from the new one you put in...

I know this is a few yrs. later, but on Larry's old coach (!), I tried his "trick", but it didn't work for me at least.  Anyone have other suggestions?

Now even more years later, has anyone found a solution if the screw does not work?
