Exhaust Pipe Installation

Temporarily install the sensor to the exhaust pipe by hand.

Using SST, tighten the sensor.

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}

HINT:

1. Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (LandCruiser RM000003YMD00TX.html).
   
2. Make sure SST and the wrench are connected in a straight line.
   

Connect the sensor connector.

Install a new gasket and the No. 2 front exhaust pipe to the exhaust manifold with 2 new nuts.

Torque:

54 N*m{554 kgf*cm, 40 ft.*lbf}

Connect the heated oxygen sensor connector.

Install the stopper bracket with the 2 bolts.

Torque:

19 N*m{194 kgf*cm, 14 ft.*lbf}

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

Minimum free length:

43 mm (1.693 in.)

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

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

NOTICE:

1. Be sure to install the gasket so that it faces the correct direction.
   
2. Do not reuse the gasket.
   
3. Do not damage the gasket.
   
4. When connecting the exhaust pipe, do not push in the gasket with the exhaust pipe.

Connect the front exhaust pipe to the front No. 2 exhaust pipe with the 2 bolts.

Torque:

48 N*m{489 kgf*cm, 35 ft.*lbf}

Connect the heated oxygen sensor connector.

Connect the center exhaust pipe to the 3 exhaust pipe supports.

Install the center exhaust pipe with the 2 compression springs and 4 bolts.

Torque:

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

Install the tailpipe to the exhaust pipe support.

Install a new gasket to the center exhaust pipe.

Install the 2 bolts.
