      Note


      • Do not damage the No. 2 camshaft.

      • Never grip areas other than the hexagonal portion, as this may cause damage.

      *a Straight Pin Hole
      *b Straight Pin

      Align and attach the straight pin of the No. 2 camshaft with the straight pin hole of the camshaft timing exhaust gear assembly.

      *1 Camshaft Timing Exhaust Gear Assembly
      *a INCORRECT
      *b CORRECT
      *c Clearance
      *d Camshaft Flange
      *e No Clearance

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

      Note

      Be sure not to remove the other 4 bolts. If removing the bolts, exchange the camshaft timing exhaust gear assembly.

    4. Fix the camshaft timing exhaust gear assembly with the flange bolt.

      *a Straight Pin
      *b Straight Pin Hole

      Align the straight pin hole and straight pin and install the camshaft timing gear assembly to the camshaft.

    3. Lightly press the gear against the camshaft and turn the gear. Push further at the position where the straight pin enters the straight pin hole.

      Note

      Be sure not to turn the camshaft timing gear assembly in the retard direction (the right angle).

      *1 Camshaft Timing Gear Assembly
      *a INCORRECT
      *b CORRECT
      *c Clearance
      *d Camshaft Flange
      *e No Clearance

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

      Note


      • Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break.

      • Be sure not to remove the other 3 bolts. If removing the bolts, exchange the camshaft timing gear assembly.

    5. With the camshaft timing gear assembly fixed in place, install the flange bolt.

      Torque:
      78 N*m  { 795 kgf*cm, 58 ft.*lbf }

    6. Check that the camshaft timing gear assembly can move in the retard direction (the right angle), and is locked at the most retarded position.

  3. INSTALL CAMSHAFT AND NO. 2 CAMSHAFT


    1. B001DNQE04

      Apply clean engine oil to the camshaft cams and cylinder head journals.

    2. Install the chain sub-assembly to the camshaft timing gear assembly with the paint mark of the link aligned with the timing mark of the camshaft timing gear assembly.

      *a Paint Mark
      *b Timing Mark
    3. B001HQ4

      Temporarily install the 4 No. 2 camshaft bearing caps using the 8 bolts as shown in the illustration.

    4. Install the chain sub-assembly to the No. 2 camshaft, and then install the No. 2 camshaft to the cylinder head sub-assembly.

      Tech Tips

      Place the chain sub-assembly on the camshaft timing gear assembly but do not engage the teeth of the sprocket and the chain sub-assembly.

    5. Move the camshaft in the direction shown in the illustration to loosen the chain sub-assembly, and align the paint mark on the camshaft timing gear assembly and chain sub-assembly and connect the chain sub-assembly to the camshaft timing gear assembly.

      *3 Valve Stem Cap
      *a INCORRECT
      *b CORRECT

      Make sure that the No. 1 valve rocker arm sub-assemblies are installed as shown in the illustration.

    7. B001CTF

      Temporarily install the No. 1 camshaft bearing cap and 4 No. 2 camshaft bearing caps using the 12 bolts.

    8. B001HV9E03

      Install the 20 bolts in the order shown in the illustration.

      Torque:
      16 N*m  { 158 kgf*cm, 11 ft.*lbf }

  4. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY


    1. B001DZ8E25
      Text in Illustration
      *a Plunger
      *b Stopper Plate
      *c Hexagon Wrench

      Move the stopper plate upward to release the lock and push the plunger deep into the tensioner.

    2. Move the stopper plate downward to set the lock and insert a hexagon wrench into the hole of the stopper plate.

    3. Install a new gasket and the No. 1 chain tensioner assembly with the bolt and nut.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

      Note

      Remove the hexagon wrench after installing the timing chain guide.

    4. Install a new gasket to the timing chain cover plate.

    5. Install the timing chain cover plate to the timing chain cover sub-assembly with the 2 bolts.

      Torque:
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

  5. CHECK NO. 1 CYLINDER TO TDC/COMPRESSION


    1. Check that the No. 1 cylinder is set to TDC/compression.

        Text in Illustration
        *a Timing Mark
        *b Groove
        *c Approximately 13°

        Rotate the crankshaft two full rotations, and then check that all timing marks are in the position shown in the illustration.

        If the timing marks do not match, set the chain sub-assembly again.
