Checking Exhaust SystemNBS000J5
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If anything is found, repair or replace damaged parts.
Removal and InstallationNBS000J6
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the insulator edge.

Refer to GI-11, "Components" for symbol marks in the figure.
REMOVAL

Disconnect each joint and mounting with power tool.

When removing main muffler, remove main muffler mounting bracket bolts.

For removing and installing parts around propeller shaft, be careful of the following caution.
CAUTION:
Be sure to prevent propeller shaft from interfering parts and tools. If necessary, install protector to
propeller shaft to prevent damage.
For propeller shaft protector, refer to PR-5, "
REAR PROPELLER SHAFT" .
INSTALLATION
Note the following, and install in the reverse order of removal.

Tighten main muffler mounting bracket bolts in numerical order
as shown in the figure.
When reassembling main muffler only.
1. Temporarily tighten connecting flange (A).
2. Move main muffler front/rear/left/right so that clearance between
tail tube and bumper is even.
3. Tighten connecting flange (A) to the specified torque.
When reassembling center muffler.
1. Temporarily tighten connecting flanges in order of (A) and (B).
2. Move main muffler front/rear/left/right so that clearance between
tail tube and bumper is even.
3. Tighten connecting flanges in order of (A) and (B) to the speci-
fied torque.
When reassembling exhaust front tube.
1. Temporarily tighten connecting flanges of center muffler in order of (B) and (C).
2. Move main muffler front/rear/left/right so that clearance between tail tube and bumper is even.
3. Tighten connecting flanges in order of (B) and (C) to the specified torque.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.

INSPECTION AFTER INSTALLATION

Make sure that clearance between tail tube and bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Make sure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
