  3. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY

    Tech Tips

    Perform "Inspection After Repair" after replacing the camshaft timing gear assembly.



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

    2. B006IAVC01
      *a Knock Pin
      *b Knock Pin Hole

      Align and fit the knock pin of the camshaft to the knock pin hole of the camshaft timing gear assembly.

    3. B006J24C01
      *1 Camshaft Timing Gear Assembly
      *a Camshaft Flange
      *b No Gap

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

    4. B006I6S

      Tighten the bolt with the camshaft timing gear assembly secured in place.

      Torque:
      54 N*m  { 551 kgf*cm, 40 ft.*lbf }

      Note

      When tightening the bolt, do not allow the camshaft timing gear assembly to rotate.

    5. B006IKWC01
      B006IR6 Lock

  5. INSTALL CAMSHAFT

    Tech Tips

    Perform "Inspection After Repair" after replacing the camshaft.



    1. Clean the camshaft journals.

    2. Apply a light coat of engine oil to the camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.

    3. B006IZ5C02
      *a Paint Mark
      *b Timing Mark

      Hold up the chain sub-assembly, align the timing mark with the paint mark and install the camshaft.

  6. INSTALL NO. 2 CAMSHAFT

    Tech Tips

    Perform "Inspection After Repair" after replacing the No. 2 camshaft.



    1. Clean the No. 2 camshaft journals.

    2. Apply a light coat of engine oil to the No. 2 camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.

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

  7. 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 for 1 camshaft bearing cap, install the camshaft bearing cap with the bolts in the order shown in the illustration.

      B006I5UC01
      *a Service bolt and spacer (Used to temporarily secure the camshaft housing sub-assembly) *b Knock Pin
      *c Paint Mark *d Timing Mark
      *e The removal order of the service bolts and spacers for temporarily tightening the camshaft housing sub-assembly *f The installation order of the parts
      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 separate, resulting in oil leaks. 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 knock pin and timing mark of the camshaft are as shown in the illustration.

    2. B006I9QN02

      Tighten the 10 bolts in the order shown in the illustration.

      Torque:
      16 N*m  { 163 kgf*cm, 12 ft.*lbf }

    3. Check the torque of each bolt again.

  8. INSTALL CAMSHAFT TIMING SPROCKET


    1. B006I5OC02
      *a Paint Mark
      *b Timing Mark

      Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft slightly counterclockwise to release the chain sub-assembly.

      Note

      Do not turn the camshaft more than necessary.

    2. Align the paint mark with the timing mark to install the chain sub-assembly.

    3. B006J8HC02
      *a 14 mm Union Nut Wrench
      *b Torque Wrench Fulcrum Length
      *c Hold
      *d Turn

      Using SST, a 14 mm union nut wrench and a wrench, hold the hexagonal portion of the No. 2 camshaft and install the camshaft timing sprocket to the No. 2 camshaft with the bolt.

      SST
      09961-00950
      Torque
      Specified tightening torque
      54 N*m (551 kgf*cm, 40 ft.*lbf)

      Note


      • Make sure to securely hold the No. 2 camshaft.

      • As the crankshaft cannot be rotated counterclockwise due to the one-way clutch assembly, if the camshaft timing gear assembly rotates to the point that the timing mark cannot be seen, it will not be possible to adjust the valve timing with the engine installed to the vehicle.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using a 14 mm union nut wrench (fulcrum length of 25 mm (0.984 in.)) + SST (fulcrum length of 150 mm (5.91 in.)) + torque wrench (fulcrum length of 255 mm (10.0 in.)): 32 N*m (326 kgf*cm, 24 ft.*lbf)

  9. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY


    1. B006IOOC02
      *a Cam
      *b Hook
      *c Plunger
      *d Pin
      *e Correct
      *f Incorrect
      *g Push
      *h Raise

      Raise the cam, then fully push in the plunger and engage the hook with the pin so that the plunger is in the position shown in the illustration.

      Note

      Make sure that the cam engages with the first tooth of the plunger to allow the hook to pass over the pin.

    2. B006HZP

      Install a new gasket, the bracket and No. 1 chain tensioner assembly to the timing chain cover sub-assembly with the 2 nuts.

      Torque:
      12 N*m  { 122 kgf*cm, 9 ft.*lbf }

      Note

      If the hook releases the plunger while the No. 1 chain tensioner assembly is being installed, set the hook again.

    3. B006J9CN01

      Using SST, hold the crankshaft pulley.

      SST
      09213-58014   ( 91551-80840 )
      09330-00021

      Note


      • Make sure to securely hold the crankshaft.

      • The crankshaft cannot be rotated counterclockwise due to the one-way clutch assembly. When releasing the hook of the No. 1 chain tensioner assembly, if the timing marks and paint marks become misaligned to the point where they cannot be seen due to the crankshaft being rotated, it will not be possible to adjust the valve timing with the engine installed to the vehicle.

    4. B006I1OC01
      *a Hook
      *b Release

      Using a wrench, rotate the camshaft clockwise slightly and check that the hook is released.

    5. B006HIWC01
      *a Plunger
      *b Plunger is extended

      Using a wrench, turn the camshaft counterclockwise and check that the plunger is extended.

      Tech Tips

      Make sure that a click sound is heard to confirm that the plunger has extended.

    6. Remove SST.

  10. INSTALL NO. 2 CHAIN VIBRATION DAMPER


    1. B006INMC01
      *a Torque Wrench Fulcrum Length

      Using SST, install the No. 2 chain vibration damper to the No. 1 camshaft bearing cap with the 2 bolts.

      SST
      09961-00950
      Torque
      Specified tightening torque
      10 N*m (102 kgf*cm, 7 ft.*lbf)

      Tech Tips
