PROCEDURE


  1. INSTALL NO. 1 CAMSHAFT BEARING


    1. Clean both surfaces of the 2 No. 1 camshaft bearings.

      Note

      Do not apply engine oil to the No. 1 camshaft bearings or the contact surfaces.

    2. Install the 2 No. 1 camshaft bearings to the camshaft bearing cap.

    3. B00449JC02
      *1 Vernier Caliper

      Using a vernier caliper, measure the distance between the camshaft bearing cap edge and the No. 1 camshaft bearing edge.

      Difference between (A) and (B)
      0.7 mm (0.0276 in.) or less

      Note

      Position the No. 1 camshaft bearings to the center of the camshaft bearing cap by measuring dimensions A and B.

  2. INSTALL NO. 2 CAMSHAFT BEARING


    1. Clean both surfaces of the 2 No. 2 camshaft bearings.

      Note

      Do not apply engine oil to the No. 2 camshaft bearings or the contact surfaces.

    2. Install the 2 No. 2 camshaft bearings to the camshaft housing sub-assembly.

    3. B004385C01
      *1 Vernier Calipers

      Using a vernier caliper, measure the distance between the camshaft bearing cap edge and the No. 2 camshaft bearing edge.

      Dimension (A)
      1.05 to 1.75 mm (0.0413 to 0.0689 in.)

      Note

      Position the No. 2 camshaft bearings to the center of the camshaft bearing cap by measuring dimension A.

  3. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY


    1. Clamp the hexagonal portion of the camshaft in a soft jaw vise.

  6. INSTALL CAMSHAFT BEARING CAP


    1. Check the marks and numbers on the camshaft bearing caps, and then remove the service bolts and spacers in the order shown in the illustration. Immediately after removing the service bolts and spacers, install the camshaft bearing caps with the 15 bolts in the order shown in the illustration.

      B00442KC01
      *a The removal order of the Service Bolts and Spacers for temporarily tightening the Camshaft Housing Sub-assembly *b The installation order of the parts

      *e Paint Mark *f Straight Pin
      Torque:
      27 N*m  { 275 kgf*cm, 20 ft.*lbf }

      Note

      If the bolts are loosened all at once, FIPG on the camshaft housing sub-assembly and cylinder head sub-assembly may peel off, resulting in oil oozing. Therefore, be sure to remove the service bolts and spacers from one camshaft bearing cap at a time.

      Tech Tips

      Make sure that the orientation of the straight pin, timing mark and paint mark of the camshaft are as shown in the illustration.
