  1. Assign bearing shells to upper crankcase section

    IMPORTANT The bearing shells are marked on the side in color. The upper crankcase section carried letters, which correspond to the sequence of the bearing shells (1, 2, 3, 4, 5, 6, 7) in the upper crankcase section. The bearing shells should be selected according to the letter sequence (only shown in picture with "b"). Letters "g" and "r" may also be used. The following letters require the following wheel offset code numbers of bearing shells (upper section):

    b (blue) = wheel offset code number 52

    g (yellow) = wheel offset code number 54

    r (red) = wheel offset code number 56

  2. Assign bearing shells to lower crankcase section

    IMPORTANT The bearing shells are marked on the side in color. Letters for assigning the bearing shells to the bottom part of the crankcase are included on the crankshaft journal. Select the bearing shells to match the letters.
