  3. SET CAMSHAFT TIMING GEAR ASSEMBLY (for Bank 2)


    1. A01GNBWE01

      Check the camshaft timing gear position.

      Tech Tips

      When reusing the camshaft timing gear, make sure that the groove labeled A is positioned within the mark labeled B. If the groove is not positioned within the mark, perform the following procedures to align the groove with the mark.

    2. Set the camshaft timing gear position.


      1. Turn the camshaft timing gear's eccentric shaft keyway part counterclockwise by hand and set it to the maximum retard angle.

        Tech Tips

        The position where the eccentric shaft stops is the maximum retard angle.

        Note

        When turning the eccentric shaft keyway part, do not use any tools as the keyway part may be damaged.

      2. Turn the eccentric shaft clockwise until the groove labeled A and mark labeled B are aligned as shown in the illustration.

        Tech Tips


        • Make sure that the groove labeled A is positioned as close as possible to the center of the mark labeled B.
