Newspaper method;

Cut newspaper into approx 1" strip, soak in oil, verify thickness with caliper, lay it across the bearing, tighten bearing,
Does crank turn easily?
yes, remove shim and recheck
no - just right as long as crank turns easily w/o paper
proceed until all bearings are gone though doing one at a time.

Pretty much like the foil method but using oiled paper.
