Air Cleaner Element Service

NOTE: Do not change the air cleaner element configuration
from the factory installed configuration. If equipped with
a single element or dual element, that configuration must
stay with the vehicle. Failure to comply may affect engine
performance.

1. Unhook the holddown latches and remove the inlet lid
from air cleaner housing. Remove the filter element
carefully and slowly, then discard the old element.
2. Wipe the inside of the air cleaner housing with a clean,
damp cloth. Be sure to clean the gasket sealing surface.
DO NOT use compressed air for this cleaning!

3. Visually inspect the air cleaner housing for damage or
distortion, which could allow unfiltered air to enter the
engine. Inspect to be sure that the rubber dust unloader
valve at bottom of housing is in place, free of debris, and
not cracked.
4. Inspect the new air filter element for a damaged or
nonresilient rubber gasket. Inspect the air filter element
body for dents or excessive pleat bunching. If any of
the mentioned conditions exist, obtain and install an
alternate new air filter element from your IC Bus or
International dealer.
5. Carefully install the new air filter element into the air
cleaner housing.
6. Seat and install the inlet lid squarely onto air cleaner
housing; hook and latch inlet lid to air cleaner housing
with holddown latches.
7. When servicing is completed, reset air restriction gauge
by pushing and holding the reset button and releasing
it. The yellow indicator will drop below the window. The
air restriction gauge is now ready for the next operating
cycle.
