      Upon further consideration I did a little calculation. There are 28
      teeth on the crank gear so if it was one tooth off it would be about 12.9°.
      Assuming major wear of 10% of the pitch, that would give a backlash of
      about 1.3° which is enough to make a slight difference in the power band
      but not much assuming the cam is continuously loaded.

      Are you the same Volvobub that sells a lot of parts on ebay? I have
      bid on a fair number of those parts but have been beat out because I
      was unable to bid at the close of the auction.

      Since they are not mine, I have no way of knowing, although I did buy a used
      set from the same guy a year ago. Close examination reveals wear patterns
      so minor as to be undetectable except that original grinding marks are
      fading in the wear areas. (About what I saw in an M410 when I had
      its bearings replaced at 200k miles.)
      Based on my experience with quite a few fiber gears, it's gotta be a lot
      better than any of them!

        Where did you get the replacement bearings for your
        M410? I've got 3 M410s and I'm planning on taking
        a couple apart to get new(ish) syncros and replacing
        the bearings and putting it all together to get a
        good replacement M410.

        I've read that there are replacement bearings that
        involve replacing ball bearings with needle bearings.

          The bearings were furnished by Maquinarias y Equipos Romero, S.A. in
          Panama over 20 years ago.
          While I intend to rebuild another M410 at some future time, I have not
          found (or eagerly sought) a source of replacements. Since I have a spare
          tranny I thought I would change and tear the old one down first.

          Sorry, I'm not much help on this one.
