        A01BGA6 Rubber Piece
        A01BI0O Vinyl Tape

        Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.

        Tech Tips

        2 advance side paths are provided in the groove of the camshaft. Plug one of the paths with a rubber piece.

      3. Break through the tape over the advance side path, and then break through the tape over the retard side path on the opposite side from the hole over the advance side path as shown in the illustration.

        *a Retard Side Path
        *b Advance Side Path

        Apply compressed air at approximately 200 kPa (2.0 kgf/cm2, 28 psi) to the two paths accessible through the holes in the tape.

        CAUTION:

        Some oil splashing will occur. Cover the paths with a piece of cloth.

        *a Retard Side Path
        *b Advance Side Path
        *c Decompress
        *d Hold Pressure

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

        OK
        Gear rotates in the advance direction.

        Tech Tips

        This operation releases the lock pin which holds the timing gear in the most retarded position.

      6. When the camshaft timing gear assembly reaches the most advanced position, release the air pressure from the retard side path and advance side path in that order.

        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.

    3. Check for smooth rotation.


      1. Rotate the camshaft timing gear assembly within its movable range several times, but do not turn it to the most retarded position. Check that the gear rotates smoothly.

        CAUTION:

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

    4. Check the lock in the most retarded position.


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

  17. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY


    1. Check that the camshaft timing gear assembly does not turn by mounting the hexagon wrench head portion of the camshaft in a vise through aluminum metal cap and so on.

      Note

      Be sure not to damage the camshaft.
