      Note:

      Install the No. 1 camshaft bearing cap and 5 No. 2 camshaft bearing caps with the front marks facing the front of the engine.

  5. INSTALL CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

    1. A421778C01

      *a

      Paint Mark

      *b

      Timing Mark

      Align the paint mark of the chain plate with the timing mark of the camshaft timing exhaust gear assembly and install the chain sub-assembly.

    2. Install the camshaft timing exhaust gear assembly to the No. 2 camshaft with the knock pin aligned with the pin hole.

    3. A421779C01

      *a

      Hold

      *b

      Turn

      *c

      Torque wrench with a fulcrum length of 260 mm (10.24 in.)

      *d

      SST with a fulcrum length of 100 mm (3.94 in.)

      Using a wrench to hold the hexagonal portion of the No. 2 camshaft, install the bolt using SST.

      09249-37010

      without SST

      54 N*m

      551 kgf*cm

      40 ft.*lbf

      with SST

      39 N*m

      398 kgf*cm

      29 ft.*lbf

      Tip:

      • This torque value is effective when SST is parallel to the torque wrench.

      • The "with SST" torque value is effective when using SST with a fulcrum length of 100 mm (3.94 in.).

      • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.24 in.).

      • If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values.
