  5. The combined thickness of the left and right adjusting shims is obtained by the following formula.

    C2 = B - A + 0.110 mm {0.00433 in} C2 = B - A + 0.200 mm {0.00787 in}

  6. If the combined thickness of the previously installed adjusting shims is between C1 and C2, use the shims as they are.
  7. If the combined thickness of the previously installed adjusting shims is not between C1 and C2, or if the adjusting shims have to be replaced, select two appropriate adjusting shims from the table below.
