REMOVAL
Disconnect each joint and mounting.
INSTALLATION
Note the following, and install in the reverse order of removal.

If exhaust front tube stud bolts were removed, and install them and tighten to the specified torque below.
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 the heat
insulator, remove them.

EXHAUST SYSTEM


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 and bolts on the exhaust manifold side, and mounting bolts
and nuts on the vehicle 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.
Seal Bearing (QR20DE)
1. Securely insert seal bearing into exhaust manifold and three
way catalyst assembly side in the direction as shown in the fig-
ure.
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring large diameter side facing to exhaust front tube
flange, tighten mounting nut.
3. Make sure that stud bolt does not interfere with flange of
exhaust front tube.
INSPECTION AFTER INSTALLATION

Make sure that clearance between tail tube and rear 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.

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBDS0007G
Observe the following precautions when disassembling and assembling drive shaft.

Joint sub-assembly does not disassemble because it is non-overhaul parts.

Perform work in a location which is as dust-free as possible.

Before disassembling and assembling, clean the outside of parts.

Prevention of entry of foreign objects must be taken into account during disassembly of the service loca-
tion.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of danger of lint adhering
to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
