12.29 Changing the glass fiber yarn filling of the main silencer
Warning
Danger of burns
The exhaust system gets very hot when the vehicle is driven.
–
Allow the exhaust system to cool down before performing any work on the vehicle.
Info
Over a period, the fibers of the glass fiber yarn vanish into the air, and the silencer "burns out".
Not only is the noise level higher, the performance characteristic changes.
The operations are the same for the left and right sides.
Preparatory work
–
Remove the main silencer. ( p. 68)
