Air Cleaner and Air Intake System
3. When servicing the air cleaner, check the air
cleaner base, and cover/housing assembly. Make
sure it is secure and not bent or damaged. On a
heavy-duty air cleaner, unsnap the latches and
clean out the lower swirl/dirt chamber. See Figure
4-9. Make sure the air slots in the upper section of
the housing and in the lower chamber are open.
See Figure 4-10. Clean and inspect all
components for damage or improper fit. Replace
any components which are bent or damaged.
Reassemble the lower chamber (heavy duty air
cleaners).
NOTE: Before the air cleaner is reassembled make
sure the rubber seal is in position on the stud
(standard only). Also inspect the foam seal on
the base of the filter element, do not use if the
condition of either is questionable in any way.
Replace it with a new part before
reassembling.
4. Standard Air Cleaner:
Install the serviced precleaner over the element.
Position the element/precleaner assembly on the
base and secure with the wing nut. Reinstall the air
cleaner cover and tighten securely. See Figure 4-5.
Heavy-Duty Cyclonic Cleaner:
Place the precleaner over the element and install
it as an assembly into the cover/housing. Insert
the small end first, into the housing, so the larger
end with the foam seal is out (visible). Secure with
the wing nut (if used). Secure the cover/housing
with the latches. See Figure 4-11.
Air Cleaner Components
Whenever the air cleaner cover is removed, or the
paper element or precleaner is serviced, check the
following:
Standard Air Cleaner
Air Cleaner Element Cover and Seal
Make sure the element cover is not bent, distorted or
damaged. Make sure the wing nut and rubber sleeve
seal on the base stud are in place and in good
condition, ensuring the element is sealed against
leakage.
If the air cleaner element has a foam seal on the
bottom, make sure it is in good condition and not
damaged. See Figure 4-12.
Heavy-Duty Cyclonic Air Cleaner
Air Cleaner Housing, Swirl/Dirt Chamber, Latch
Clips
Make sure the main housing, lower swirl/dirt chamber,
mounting hardware and latches are not damaged, bent
or broken; affecting the sealing ability and operation of
air cleaner housing. Clean and check all components
as well as the airflow passages.
Air Cleaner Base
Make sure the air cleaner base is secured tightly to
carburetor and not cracked, bent or damaged,
preventing a proper seal.
Breather Tube
Make sure the breather tube is in good condition and
connected to the air cleaner base or adapter and the
breather cover. Replace the tube if it is cracked or
damaged.
