    Pop Quiz: M20 Main/Rod Bearing orientation

    Greetings,

    Well I reluctantly make a thread about this because A: I should have kept track of this and B: I bet this information is out there I just can't find it. But its been almost 2 years since I disassembled the motor so you'll have to excuse me. My question pertains to the orientation of the bearings based on the tangs. On the main bearings they seem to only fit in one way and that is with the tangs on the same side. But with the rod bearings it seems they fit both directions. So which is correct?

    I included some photos here of the rods for clarity. Photo 1 is same side and photo 2 is opposite sides. Let me know the deal!

      The information is actually in your picture-
      if you look, you can see the shadow the tangs made on
      the cap and rod...

      Mains go the other way.
