      *1 Plunger

      With the lock of the stopper plate released, slightly rotate the camshaft clockwise and keep it in that position.

      Note

      Be careful not to damage the oil delivery pipe.

      Tech Tips

      Rotating the camshaft clockwise will cause pressure to be applied to the tensioner plunger.

      *a Hexagon Wrench

      Remove the screwdriver from the chain tensioner service hole. Move the stopper plate to the position shown in the illustration. Then insert a hexagon wrench into the hole.

      Tech Tips


      • If the wrench cannot fit into the hole, slightly rotate the camshaft counterclockwise, and then clockwise. Then insert the wrench.

      • To prevent the wrench from falling out, use tape to fix the wrench in place.

    9. A01BBS5E01

      Remove the camshaft timing gear or sprocket bolt and camshaft timing gear or sprocket from the No. 2 camshaft.

  13. REMOVE CAMSHAFT

      Uniformly loosen the 21 bearing cap bolts in several passes in the sequence shown in the illustration.

    2. Remove the 9 bearing caps, oil delivery pipe, O-ring and No. 2 camshaft.

      Note


      • Uniformly loosen the bolts while keeping the camshafts level.

      • Do not pry the camshaft with a tool as an excessive amount of force may be applied to it.

    3. A01BAKJE01

      Remove the camshaft while holding the timing chain.

    4. A01BHYFE01

      Secure the timing chain with a string as shown in the illustration.

      Note

  16. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY


    1. Check the lock of the camshaft timing gear assembly.


      1. Mount the camshaft in a vise and confirm that the camshaft timing gear assembly is locked.

        Note

        Do not damage the camshaft.

    2. Release the lock pin.


      1. Clean the camshaft journal with non-residue solvent.

        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.
