REMOVAL
Disconnect each joint and mounting using power tool.
INSTALLATION
Note the following, and install in the reverse order of removal.
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.
• 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. 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 bearing according to the following instructions.
CAUTION:
The structure of seal bearing depends on the mounting por-
tion. When installing seal bearings, be careful not to install
wrong one.
