I take it by big you mean small? If the difference in more than just a few thou not really practicable (esp if time considered) Older firms (and some on Forum) will have a jig for resizring. However there is no going back the other way to fit a smaller crank so the crank needs to be uncracked and likely to live long. Any poor fit of the cap halves should be corrected first, hopefully requiring very little corrction.
