    2. While raising up the No. 2 chain tensioner, insert a pin with a diameter of 1.0 mm (0.039 in.) into the hole to fix it in place.

  2. INSTALL CHAIN SUB-ASSEMBLY (for Bank 2)


    1. A01GLDDE01

      Align the No. 1 chain's orange mark plates with the camshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.

    2. A01GKJPE01

      Align the No. 1 chain's orange mark plate with the crankshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.

    3. A01GLOHE01

      Align the No. 2 chain's mark plates (yellow) with the timing marks (1-dot mark) of the camshaft timing gear assembly and camshaft timing exhaust gear assembly, and attach the No. 2 chain to the gears as shown in the illustration.

      Tech Tips

      The crankshaft timing gear and camshaft exhaust gear assembly will be installed with the No. 1 and No. 2 chains connected to the gears.

    4. Install the crankshaft timing gear to the crankshaft.

    5. Align and attach the knock pin of the No. 1 camshaft with the pin hole of the camshaft timing gear assembly.

    6. Using the hexagonal portion of the No. 2 camshaft, align and attach the knock pin of the No. 2 camshaft with the pin hole of the camshaft timing exhaust gear assembly.

    7. Remove the pin from the No. 2 chain tensioner.

  3. INSTALL NO. 1 CHAIN VIBRATION DAMPER (for Bank 2)

  4. INSTALL CHAIN TENSIONER SLIPPER (for Bank 2)

    Tech Tips

    If you cannot install the chain tensioner slipper due to the tension of the chain, use the hexagonal portion of the camshaft to loosen the chain, and then install the chain tensioner slipper.

  5. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY (for Bank 2)


    1. A01GHN8E01

      Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner.

    2. Move the stopper plate downward to set the lock, and insert a hexagon wrench into the hole of the stopper plate.

    3. A01GNLW

      Install the chain tensioner with the 2 bolts.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

  6. INSTALL NO. 3 CHAIN TENSIONER ASSEMBLY


    1. A01GLNRE01

      Install the chain tensioner with the 2 bolts.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    2. While pushing down the No. 3 chain tensioner, insert a pin with a diameter of 1.0 mm (0.039 in.) into the hole to fix it in place.

  7. INSTALL CHAIN SUB-ASSEMBLY (for Bank 1)


    1. A01GHNYE01

      Align the No. 1 chain's orange mark plates with the camshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.

    2. A01GIYWE01

      Align the No. 1 chain's orange mark plate with the crankshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.

    3. A01GMK6E01

      Align the No. 2 chain's mark plates (yellow) with the timing marks (1-dot mark) of the camshaft timing gear assembly and camshaft timing exhaust gear assembly, and attach the No. 2 chain to the gears as shown in the illustration.

      Tech Tips

      The crankshaft timing gear and camshaft exhaust gear assembly will be installed with the No. 1 and No. 2 chains connected to the gears.

    4. Install the crankshaft timing gear to the crankshaft.

    5. Align and attach the knock pin of the No. 3 camshaft with the pin hole of the camshaft timing gear assembly.

    6. Using the hexagonal portion of the No. 4 camshaft, align and attach the knock pin of the No. 4 camshaft with the pin hole of the camshaft timing exhaust gear assembly.

      Note

      Because the gears' timing mark positions may shift due to looseness of the No. 1 chain, use the hexagonal portion of the camshaft to hold the No. 3 camshaft in place until the No. 1 chain tensioner is installed.

    7. Remove the pin from the No. 2 chain tensioner.

  8. INSTALL CHAIN TENSIONER SLIPPER (for Bank 1)

    Tech Tips

    If you cannot install the chain tensioner slipper due to the tension of the chain, use the hexagonal portion of the camshaft to loosen the chain and install the chain tensioner.

  9. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY (for Bank 1)


    1. A01GHN8E01

      Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner.
