Exhaust Pipe Installation

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

Minimum free length:

38.5 mm (1.52 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 assembly.

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 front exhaust pipe assembly, do not push in the gasket with the front exhaust pipe assembly.
   

Install a new gasket and the front exhaust pipe assembly and 2 compression springs with the 2 bolts.

w/ Urea SCR System:

Torque:

Specified tightening torque:

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

HINT:

1. Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
   
2. When using a union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 38N*m (385 kgf*cm, 28 ft.*lbf)
   

w/o Urea SCR System:
Install the front exhaust pipe assembly and 2 compression springs with the 2 bolts.

Torque:

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

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

for 3 Door:
Connect the center exhaust pipe assembly to the 2 exhaust pipe supports.

for 5 Door:
Connect the center exhaust pipe assembly to the 3 exhaust pipe supports.

Install the center exhaust pipe assembly with the 2 bolts.

Torque:

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

Using a 14 mm union nut wrench, install the No. 4 exhaust gas temperature sensor to the center exhaust pipe assembly.

Torque:

Specified tightening torque

30 N*m {306 kgf*cm, 22 ft.*lbf}

NOTICE:

If the No. 4 exhaust gas temperature sensor is dropped, replace the new one.

HINT:

1. Calculate the torque wrench reading when changing the fulcrum length of the torque wrench (LandCruiser RM000003YMD00TX.html).
   
2. When using a union nut wrench (fulcrum length of 25 mm (0.984 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 26 N*m (268 kgf*cm, 19 ft.*lbf)
   

Attach the 2 clamps and connect the No. 4 exhaust gas temperature sensor to the sensor bracket.

Connect the connector to the No. 4 exhaust gas temperature sensor.

Install a new gasket to the tailpipe assembly.

Connect the tailpipe assembly to the exhaust pipe support.

Connect the tailpipe to the center exhaust pipe assembly.

Install the 2 bolts.

Torque:

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