      Fulcrum Length

      30 mm
      *b

      Fulcrum Length

      300 mm

      Using SST, install the air fuel ratio sensor to the exhaust manifold.

      SST
      09224-00010
      Torque:
      without SST
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }
      with SST
      40 N*m  { 408 kgf*cm, 30 ft.*lbf }

      Note


      • The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.) and a torque wrench with a fulcrum length of 300 mm (11.8 in.) Click here.

      • The "with SST" torque value is effective when SST is parallel to the torque wrench.

    1. Install the No. 1 exhaust manifold heat insulator with the 4 bolts.

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

  6. INSTALL NO. 2 MANIFOLD STAY


    1. Install the No. 2 manifold stay with the bolt and nut.

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

  7. INSTALL MANIFOLD STAY


    1. Install the manifold stay with the bolt and nut.

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

      *1 Exhaust Manifold Converter Sub-assembly
      *2 Gasket
      *3 Wooden Block

      Using a vernier caliper, measure the free length of the compression spring.

      Minimum 40.5 mm (1.59 in.)

      Tech Tips

      If the length is less than the minimum, replace the compression spring.

    2. Fully insert a new gasket to the exhaust manifold converter sub-assembly.

      *2 Front Exhaust Pipe Assembly
      *3 Gasket
      *a Space between flanges: 8.5 mm (0.335 in.)

      Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the exhaust manifold converter sub-assembly.

      Note


      • Be sure to install the gasket in the correct direction.

      • Do not reuse the gasket.

      • Do not damage the gasket.

      • Do not push in the gasket by using the exhaust pipe when connecting it.

    4. Install a new gasket to the front exhaust pipe assembly.

    5. Connect the front exhaust pipe assembly to the exhaust pipe support.

    6. Install the front exhaust pipe assembly with the 2 compression springs, 2 bolts and 2 nuts.
