                                                       If the measured value of a crankshaft journal outer di-
                                                       ameter is 65.997 mm, the journal is classified as "1" or
                                                       "Yellow" in the table. In case the crankshaft is also re-
                                                       placed by a spare part, check the identification colors of
                                                       the journals painted on the new crankshaft.
                                                       Next, check the cylinder block bearing bore identification
                                                       mark stamped on the cylinder block. If it is "A" read the
                                                       "Bearing identification mark" column to find the identifi-
                                                       cation mark of the bearing to be used. In this case, it is
                                                       "1" or "Green"
