arrester daily when driving in mud and water. Replace a cracked or
damaged arrester before operating.

2. Remove the arrester from the end of the muffler.
3. Use a non-synthetic brush to clean the arrester screen. A synthetic
brush may melt if components are warm. If necessary, blow debris
from the screen with compressed air.

damaged screen.
5. Reinstall the arrester. Torque bolt to 9-11 ft. lbs. (12-15 Nm).
