Will do. Should I lightly sand the surface of the crank (say, with 1500-grit emery paper) to smooth any scuffing, or should I just use it as-is?

Oh, I should also mention that this particular engine apparently had a tendency to break crankshafts because they were hollowed-out a bit too much, so a crankshaft that hasn't broken in over a year is worth hanging on to if I can.
