Breather Filter/Hose
1. Remove the left side panel. See page 78.
2. Remove the hose clamps from the filter and pull the filter out of the
hoses. Inspect the filter for debris. Blow gently through the filter in
the direction of the arrow to check for clogging. Replace a damaged
or clogged filter.
3. Check the hoses for cracks, deterioration, abrasion, or leaks.
Replace as needed. Reinstall the filter and hose clamps. The filter is
effective with the arrow pointing in either direction.
NOTICE: Operation of your vehicle without a breather filter can cause engine
damage. Always reinstall the breather filter after removing it for
service.
