      *a Timing Mark
      *b Timing Notch
      *c Timing Mark (Rectangle)
      *d Mark (Circle)

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

      Tech Tips

      There are 3 marks on the camshaft timing sprocket. Make sure that the timing mark (rectangle) is at the top.

    2. Check that the timing marks on both the camshaft timing sprocket and the camshaft timing gear are facing upward as shown in the illustration.

      If not, turn the crankshaft 1 complete revolution (360°) and align the marks as above.

  21. REMOVE NO. 1 CHAIN TENSIONER ASSEMBLY


    1. B001N2U

      Remove the 2 nuts, bracket, chain tensioner and gasket.

      Note

      Do not turn the crankshaft without the No. 1 chain tensioner installed.

  24. REMOVE CHAIN TENSIONER SLIPPER


    1. B001NA9

      Remove the chain tensioner slipper from the cylinder block.

  25. REMOVE NO. 1 CHAIN VIBRATION DAMPER


    1. B001LS7

      Remove the 2 bolts and chain vibration damper.

  26. REMOVE NO. 2 CHAIN VIBRATION DAMPER


    1. B001KSX

      Remove the 2 bolts and No. 2 chain vibration damper.

  27. REMOVE CHAIN SUB-ASSEMBLY


    1. B001M1I

      Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft timing gear counterclockwise to loosen the chain between the camshaft timing gears.

    2. With the chain loosened, release the chain from the camshaft timing gear and place it on the camshaft timing gear.

      Tech Tips

      Be sure to release the chain from the sprocket completely.

    3. Turn the camshaft clockwise to return it to the original position and remove the chain.

  28. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY


    1. Inspect the lock of the camshaft timing gear.

    2. B001M0OE03
      Text in Illustration
      *1 Adhesive Tape
      *a Adhesive Tape Sealing Area
      *b Prick a Hole

      After cleaning and degreasing the VVT oil hole on the intake side of the No. 1 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 cover the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

    3. Prick a hole in the tape covering the oil hole as shown in the illustration. (Procedure A)

    4. B001MJ4

      Apply approximately 150 kPa (1.5 kgf/cm2, 22 psi) of air pressure to the hole pricked 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.

    5. 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.

    6. B001LWW

      Turn the camshaft timing gear within its movable range (26.5 to 28.5°) 2 or 3 times without turning it to the most retarded position. Make sure that the camshaft timing gear turns smoothly.

    7. Remove the adhesive tape from the No. 1 camshaft bearing cap.

  29. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY


    1. B001KMV
      Text in Illustration
      *1 Flange Bolt
      *a Do not remove

      Remove the flange bolt while holding the hexagonal portion of the camshaft with a wrench, and then remove the camshaft timing gear.

      Note


      • Before removing the camshaft timing gear, make sure that the lock pin has been released.

      • B001KRNE04

        Be sure not to remove the other 4 bolts.

      • Keep the camshaft timing gear horizontal while removing it from the camshaft.

  30. REMOVE CAMSHAFT TIMING SPROCKET


    1. B001LD9

      Remove the flange bolt while holding the hexagonal portion of the camshaft with a wrench, and then remove the camshaft timing sprocket.

  31. REMOVE CAMSHAFT BEARING CAP


    1. B001KJKE02

      Uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.

    2. B001MV0E02

      Uniformly loosen and remove the 15 bearing cap bolts in the sequence shown in the illustration.

      Note

      Uniformly loosen the bearing cap bolts while keeping the camshaft housing level.

    3. Remove the 5 bearing caps.

      Tech Tips

      Arrange the removed parts in the correct order.

  32. REMOVE CAMSHAFT


    1. B001N3U

      Remove the camshaft.

  33. REMOVE NO. 2 CAMSHAFT


    1. B001LWI

      Remove the No. 2 camshaft.

  34. REMOVE NO. 1 CAMSHAFT BEARING


    1. B001N03

      Remove the 2 No. 1 camshaft bearings.

  35. REMOVE NO. 2 CAMSHAFT BEARING


    1. B001LUV

      Remove the 2 No. 2 camshaft bearings.

  36. REMOVE CAMSHAFT HOUSING SUB-ASSEMBLY


    1. B001MR2

      Remove the 2 bolts.

    2. B001N1BE02
      Text in Illustration
      *1 Protective Tape

      Remove the camshaft housing by prying between the cylinder head and camshaft housing with a screwdriver.

      Note

      Be careful not to damage the contact surfaces of the cylinder head and camshaft housing.

      Tech Tips

      Tape the screwdriver tip before use.
