EXHAUST SYSTEMPFP:20100
Checking Exhaust SystemEBS00AZ6
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 InstallationEBS003DN
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.

REMOVAL
Separate each connection as necessity.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:

Always replace exhaust gaskets and seal bearings with new ones when reassembling.

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

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

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

EXHAUST SYSTEM


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.

Install seal bearings at exhaust front tube and main muffler as follows.
CAUTION:
Do not mix the bolt and spring for seal bearing as the dimension is different for each seal bearing.
Exhaust Front Tube Side (QR20DE and QR25DE)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with
exhaust front tube flange.
Main Muffler Side (QR20DE, QR25DE and YD22DDTi)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with main
muffler flange.
INSPECTION AFTER INSTALLATION

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

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