MAINTENANCE
Foam Oil Breather Element
The foam oil breather element absorbs small amounts of liquid to pro-
tect sensors within the intake system from damage due to oil ingestion.
Check the element before each ride. Clean or replace the breather ele-
ment at each engine oil change. Inspect the foam oil breather element
any time the snowmobile has been tipped onto its left side. Clean the
element if oil is present.
NOTICE:
Operating the snowmobile with a clogged foam oil breather element
can result in severe engine damage. Always clean or replace the
element as recommended.
The foam oil breather element is located
inside the airbox.
1. Open the hood.
2. Release the airbox cover retaining
clips and remove the cover.
3. Remove the foam breather element.
4. Wash the foam element in soapy
water, then rinse thoroughly and let
dry.
Tip:
If soap and water are not readily avail-
able, remove as much liquid as possible
by pressing the foam element in paper
towels or a similar absorbent material.
5. Reinstall the dry foam element, or
install a new foam element.
Tip:
Always replace a foam element that is
brittle, cracked, crumbling or otherwise
damaged. For best performance, rou-
tinely replace the foam element with
every other engine oil change.
6. Reinstall the airbox cover. Secure
all retaining clips.
