Torque:

12 N·m {122 kgf·cm, 9 ft·lbf}


2. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR

(a) Install the No. 2 exhaust manifold heat insulator to the exhaust manifold converter sub-assembly with the 2 bolts.

Torque:

12 N·m {122 kgf·cm, 9 ft·lbf}


3. INSTALL EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY

(a) Install a new gasket onto the cylinder head sub-assembly.


(b) Temporarily install the exhaust manifold converter sub-assembly to the cylinder head sub-assembly with the 5 nuts.


(c) Tighten the 5 nuts in the order shown in the illustration.

Torque:

35 N·m {357 kgf·cm, 26 ft·lbf}

4. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR

(a) Install the No. 1 exhaust manifold heat insulator to the exhaust manifold converter sub-assembly with the 4 bolts.

Torque:

12 N·m {122 kgf·cm, 9 ft·lbf}


5. INSTALL NO. 2 MANIFOLD STAY

(a) Install the No. 2 manifold stay to the exhaust manifold converter sub-assembly and stiffening crankcase assembly with the bolt and nut.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}


6. INSTALL MANIFOLD STAY

(a) Install the manifold stay to the exhaust manifold converter sub-assembly and stiffening crankcase assembly with the bolt and nut.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}


7. INSTALL AIR FUEL RATIO SENSOR


8. INSTALL FRONT EXHAUST PIPE ASSEMBLY

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

Minimum Free Length:

41.5 mm (1.63 in.)

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


(b) Temporarily install a new gasket to the exhaust manifold converter sub-assembly.

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