INSTALL FRONT EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression spring.
| Minimum free length |
|---|
| 38.5 mm (1.52 in.) |
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.
| *1 | Gasket |
| *a | Wooden Block |
Be sure to install the gasket so that it faces the correct direction.
Do not reuse the gasket.
Do not damage the gasket.
When connecting the front exhaust pipe assembly, do not push in the gasket with the front exhaust pipe assembly.
Connect the front exhaust pipe assembly to the 2 exhaust pipe supports.
Install a new gasket and the front exhaust pipe assembly and 2 compression springs with the 2 bolts.

INSTALL UREA INJECTOR SET
INSTALL CENTER EXHAUST PIPE ASSEMBLY
Install a new gasket to the center exhaust pipe assembly.
Connect the center exhaust pipe assembly to the 2 exhaust pipe supports.
Install the center exhaust pipe assembly with the 2 bolts and 2 new nuts.

INSTALL NITROGEN OXIDES SENSOR
Temporarily install the nitrogen oxides sensor.
Install the controller portion with the 2 nuts, and then attach the connector and clamp.
| 8.0 N*m | 82 kgf*cm | 71 in.*lbf |
Using SST, install the nitrogen oxides sensor.

| Specified tightening torque | ||
| 55 N*m | 561 kgf*cm | 41 ft.*lbf |
| *a | Torque Wrench Fulcrum Length |
Replace with a new part if it is dropped or if it receives a strong impact.
Complete the installation so that there is no tension or slack in the harness of the nitrogen oxides sensor, and there is no interference.
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench (Click here).
When using SST (fulcrum length of 30 mm (1.181 in.)) + torque wrench (fulcrum length of 255 mm (10.039 in.)): 49 N*m (502 kgf*cm, 36 ft.*lbf)
INSTALL NO. 4 EXHAUST GAS TEMPERATURE SENSOR
Using a 14 mm union nut wrench, install the No. 4 exhaust gas temperature sensor to the front exhaust pipe assembly.
| Torque |
|---|
| Specified tightening torque |
| 30 N*m {306 kgf*cm, 22 ft.*lbf} |
| *a | Torque Wrench Fulcrum Length |
If the No. 4 exhaust gas temperature sensor is dropped, replace it with a new.
