Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf) for use with SST 44 N*m (449 kgf*cm, 32 ft.*lbf) for use without SST

HINT:

Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
Make sure that SST and wrench are connected in a straight line.

3. INSTALL EXHAUST MANIFOLD RH

INSTALL EXHAUST MANIFOLD RH

(a) Install the exhaust manifold RH with a new gasket and 6 nuts.

Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf)

INSTALL EXHAUST MANIFOLD RH

4. INSTALL CENTER EXHAUST PIPE ASSEMBLY

INSTALL CENTER EXHAUST PIPE ASSEMBLY

(a) Check compression springs.

(1) Check the compression springs using vernier calipers.

Specified length: 38.86 mm (1.5299 in.)

HINT:

If the result is not as specified, replace the compression spring.

INSTALL CENTER EXHAUST PIPE ASSEMBLY

(b) Install the gasket.

(1) Install a new gasket by hand onto the front exhaust pipe assembly.

(2) Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the front exhaust pipe.

NOTICE:

Be careful with the installation direction of the gasket.
Do not damage the gasket.
Do not reuse the gasket.
To ensure a proper seal, do not use the exhaust pipe to force the gasket on to the front exhaust pipe.
