    1. A01V7SAC07
      *1 Knock Pin Hole
      *2 Alignment Mark
      *a Advanced Position
      *b Retarded Position

      Check the camshaft timing gear position.

      Note


      • If the camshaft timing gear is set to the advanced position, do not let the camshaft timing gear rotate clockwise during installation.

      • If the camshaft timing gear has rotated to the most retarded position, make sure to release the lock pin and set the camshaft timing gear to the most advanced position before tightening the camshaft timing gear.

    2. A01V7NNC05
      *1 Narrow
      *2 Wide

      Install the camshaft timing gear as shown in the illustration.

    3. A01V9BUC05
      *1 Narrow
      *2 Wide

      Turn the camshaft timing gear approximately 180° counterclockwise.

    4. A01V6TOC05
      *1 Paint Mark
      *2 Matchmark

      Align the paint mark with the matchmark to install the chain.

    5. A01VB5MC25
      *1 Knock Pin Hole
      *2 Knock Pin

      Align and attach the knock pin of the camshaft with the knock pin hole of the camshaft timing gear.

    6. A01V9T8C38
      *1 Camshaft Timing Gear
      *2 Clearance
      *3 Camshaft Flange
      *a INCORRECT
      *b CORRECT
      *c No Clearance

      Check that there is no clearance between the camshaft timing gear and camshaft flange.

    7. Secure the camshaft in place by hand, and then install the installation bolt of the camshaft timing gear by hand.

      Note

      Do not use any tools to install the bolt. If the bolt is installed using a tool, the lock pin will be damaged.

    8. If the lock pin has not been released, release it.


      1. A01V83NC05
        *a Adhesive Tape Sealing Area
        *b Make a Hole

        After cleaning and degreasing the intake side VVT oil hole on the camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.

        Note

        Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

      2. Make a hole in the adhesive tape covering the oil hole as shown in the illustration. (Procedure A)

      3. A01VAHR

        Apply approximately 200 kPa (2.0 kgf/ cm2, 29 psi) of air pressure to the hole made in procedure A to release the lock pin.

        Note


        • If air leaks out, reattach the adhesive tape.

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

      4. Forcibly turn the camshaft timing gear in the advance direction (counterclockwise).

        Tech Tips

        Depending on the air pressure applied, the camshaft timing gear may turn in the advance direction without assistance by hand.

      5. Remove the adhesive tape from the camshaft bearing cap.

    9. A01V9UU

      Using a wrench to hold the hexagonal portion of the camshaft, install the bolt.

      Torque:
      85 N*m  { 867 kgf*cm, 63 ft.*lbf }

      Note

      Be careful not to damage the cylinder head or spark plug tube with the wrench.

    10. A01VB4RC04
      *1 Paint Mark
      *2 Matchmark

      Check that each matchmark of the camshaft timing gear and camshaft timing exhaust gear are aligned with each matchmark located as shown in the illustration.

      Make sure not to drop the gasket inside the timing chain cover.

    3. Remove the pin from the stopper plate.

  13. CHECK NO. 1 CYLINDER TO TDC/COMPRESSION


    1. Turn the crankshaft pulley until its timing notch (groove) and the timing mark "0" of the timing chain cover are aligned.

      A01VA14C04
      *1 Timing Mark *2 Timing Notch (Groove)
      *a Approximately 7° *b Approximately 32°

    2. Check that the timing marks of the camshaft timing gears are as shown in the illustration. If not, turn the crankshaft 1 revolution (360°) to align the timing marks as shown in the illustration.

      Tech Tips

      "A" is not a timing mark.

  14. INSTALL TIMING CHAIN COVER PLATE


    1. A01V8Q6E02

      Install a new gasket and the timing chain cover plate with the 4 bolts.

      Torque:
