Normally the dial pointer is just a snug slide-fit on the cord and you can nudge it further to the right or further to the left without unmounting the drive cord, in fact you should avoid unstringing the drive cord without a good reason as there is a bit of an art to winding them back on the right way with the right tension, etc.

But first, ascertain whether the dial pointer really is offset - tune to a radio station you definitely know the frequency of and look to see whether the pointer is dead-on that frequency on the dial. If it is, leave well alone.
