    2. B006INPC01
      *a Paint Mark
      *b Timing Mark

      Place paint marks on the chain sub-assembly in alignment with the timing marks on the camshaft timing gear assembly and camshaft timing sprocket.

  19. REMOVE NO. 2 CHAIN VIBRATION DAMPER


    1. B006IZ1N01

      Using SST, remove the 2 bolts and No. 2 chain vibration damper from the No. 1 camshaft bearing cap.

  20. REMOVE NO. 1 CHAIN TENSIONER ASSEMBLY


    1. B006HNY

      Remove the 2 nuts, bracket, No. 1 chain tensioner assembly and gasket from the timing chain cover sub-assembly.

      Note

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

  21. REMOVE CAMSHAFT TIMING SPROCKET


    1. B006IJFC02
      *a 14 mm union nut wrench
      *b Hold
      *c Turn

      While holding the hexagonal portion of the No. 2 camshaft with a wrench, remove the bolt with SST and 14 mm union nut wrench.

      SST
      09961-00950

      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.

    2. A003NFF

      While removing the chain sub-assembly, pull out the camshaft timing sprocket horizontally and then upward.

  23. REMOVE CAMSHAFT BEARING CAP


    1. B006IC3N02

      Uniformly loosen and remove the 10 bolts in the order shown in the illustration.

      Note

      Do not loosen the other 15 bolts in this step.

      Tech Tips

      Arrange the removed parts in such a way that they can be reinstalled to their original locations.

    2. Remove the bolts and camshaft bearing caps in the order shown in the illustration. Immediately after removing each camshaft bearing cap, install service bolts and spacers in the order shown in the illustration.

      B006HSBC01
      *a The removal order of the parts *b The installation order of the service bolts and spacers for temporarily tightening the camshaft housing sub-assembly
      *c Service bolt and spacer (Used to temporarily secure the camshaft housing sub-assembly) - -
      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 install the service bolts and spacers to one camshaft bearing cap at a time.

      • Do not install the camshaft bearing caps when installing the service bolts and spacers.

      Tech Tips


      • Arrange the removed parts in such a way that they can be reinstalled to their original locations.

      • Part number for the service bolt used to temporarily secure the camshaft housing sub-assembly: 91551-G0875 (15 bolts)

      • Part number for the spacer used to temporarily secure the camshaft housing sub-assembly: 90387-12048 (15 spacers)

  24. REMOVE NO. 2 CAMSHAFT


    1. A003N4H

      Remove the No. 2 camshaft from the camshaft housing sub-assembly.

  25. REMOVE CAMSHAFT


    1. A003KYK

      Hold up the chain sub-assembly and remove the camshaft from the camshaft housing sub-assembly.

    2. A003OH3

      Suspend the chain sub-assembly with a string or equivalent.

  26. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY


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

    2. B006HCPC01
      *a Do not remove

      Remove the bolt and camshaft timing gear assembly.

      Note


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

      • Do not remove the other 4 bolts.

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

      • If the camshaft timing gear assembly is to be reused, be sure to install it with the lock pin released.
