Exhaust system components,
removing and installing

WARNING!

Do not re-use any fasteners that are worn or
deformed in normal use.
Some fasteners are designed to be used only
once, and are unreliable and may fail if used
a second time. This includes, but is not
limited to, nuts, bolts, washers, circlips and
cotter pins. Always follow the
recommendations in this manual-replace
these fasteners with new parts where
indicated, and any other time it is deemed
necessary by inspection.

Note:
Always replace gaskets and self-locking nuts.
After exhaust system repairs, make sure
exhaust system is not under stress and that it
has sufficient clearance from the bodywork. If
necessary, loosen double clamps and align
muffler and exhaust pipe so that sufficient
clearance is maintained to the bodywork and
the support rings are evenly loaded.
