      *1 Straight Pin
      *a Key Groove

      Put the camshaft timing sprocket and camshaft together with the straight pin of the groove.

    2. Turn the camshaft timing sprocket clockwise while pushing it gently toward the camshaft. Push further at the position where the pin fits into the groove.

    3. Temporarily install the camshaft timing sprocket with the bolt.

  2. INSTALL CAMSHAFT

      *a Paint Mark
      *b Timing Mark

      Align the matchmarks on the timing chain plates with the timing mark of the camshaft timing sprocket and the paint mark of the timing chain respectively and install the timing chain.

  3. INSTALL NO. 2 CAMSHAFT

    *1 No. 1 Camshaft
    *2 No. 2 Camshaft
    *3 No. 3 Cylinder
    *4 No. 1 Cylinder
    *5 No. 2 Cylinder

    1. Set the No. 2 camshaft onto the cylinder head as shown in the illustration.

      Tech Tips

      Make sure that the timing marks of the camshaft timing sprocket and camshaft timing sprocket face upward.

      *1 No. 1 Camshaft Bearing Cap
      *2 No. 2 Camshaft Bearing Cap

      Place the No. 1 camshaft bearing cap and No. 2 camshaft bearing caps and tighten the bolts to the specified torque in the order shown in the illustration.

      Torque:
      No. 1 camshaft bearing cap
      15 N*m  { 153 kgf*cm, 11 ft.*lbf }
      No. 2 camshaft bearing cap
      13 N*m  { 127 kgf*cm, 9 ft.*lbf }

      Note

      Install No. 1 camshaft bearing cap and No. 2 camshaft bearing caps with the front marks facing engine front.

  4. INSTALL CAMSHAFT TIMING GEAR


    1. A01VKY3E04

      *a Paint Mark
      *b Timing Mark

      Align the matchmarks on the timing chain plates with the timing mark of the camshaft timing gear and the paint mark of the timing chain respectively and install the timing chain.

    2. Install the No. 2 camshaft with the knock pin aligned with the gear groove.

      *a Hold
      *b Turn

      Using SST, tighten the bolts onto the camshaft timing gear while holding the hexagonal portion of the No. 2 camshaft.

      SST
      09249-37010
      Torque:
      without SST
      47 N*m  { 479 kgf*cm, 35 ft.*lbf }
      with SST
      37 N*m  { 347 kgf*cm, 25 ft.*lbf }

      Tech Tips


      • This torque value is effective when SST is parallel to the torque wrench.

      • The "with SST" torque value is effective when using SST with a fulcrum length of 100 mm (3.94 in.).

      • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.24 in.).

      • If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values Click here.

  5. TIGHTEN CAMSHAFT TIMING SPROCKET ASSEMBLY
