        *1 Advanced Side Path
        *2 Retard Side Path

        Apply approximately 200 kPa (2.0 kgf/cm2, 28 psi) of air pressure to the 2 opened paths.

        CAUTION:

        Cover the paths with a piece of cloth when applying pressure to prevent oil from spraying.

      4. A01NHL9E06

        Check that the camshaft timing gear assembly rotates in the advance direction when reducing the air pressure applied to the retard side path.

        Tech Tips

        This operation releases the lock pin at the most retarded position.

      5. When the camshaft timing gear assembly reaches the most advanced position, release the air pressure first from the retard side path and next from the advance side path.

        Note

        Do not release the air pressure from the advance side path first. The gear may abruptly shift in the retard direction and break the lock pin.

    8. Check for smooth rotation.


      1. Turn the camshaft timing gear assembly within its movable range (21°) 2 or 3 times, but do not turn it to the most retarded position. Make sure that the gear turns smoothly.

        Note

        Do not use air pressure to perform the smooth operation check.

    9. Check the lock in the most retarded position.


      1. Confirm that the camshaft timing gear assembly locks at the most retarded position.

    10. A01ND8ZE03
