Filter Element Replacement
1. Unlatch the latches, open the air cleaner body and
withdraw the element as follows (Figure 7-5):
a. RELEASE THE SEAL GENTLY. The filter element
fits tightly over the outlet tube, creating the critical
seal on the inside diameter of the filter endcap. The
filter should be removed gently to reduce the
amount of dust dislodged. There will be some initial
resistance, similar to breaking the seal on a jar.
b. AVOID DISLODGING DUST FROM THE FILTER.
Gently pull the filter off the outlet tube and out of the
housing. Avoid knocking the filter against the
housing (Figure 7-6).
2. Clean the element as outlined in ELEMENT CLEANING.
Replace the element after six cleanings or annually,
whichever comes first.
3. Inspect all parts of the intake system and air cleaner. Be
sure to clean the sealing surface of the outlet tube and
the inside of the outlet tube.
4. Install the cleaned or new element into the air cleaner
body as follows:
a. INSPECT THE FILTER FOR DAMAGE. Always
look for filter damage, even if a new filter element is
being installed. Pay special attention to the inside of
the open end (sealing area). Do not install a
damaged filter.
b. INSERT THE FILTER PROPERLY. The seal area is
on the inside of the open end of the primary filter. A
new filter has a dry lubricant to aid installation. The
critical sealing area will stretch slightly, adjust itself
and distribute the sealing pressure evenly. To
complete a tight seal, apply pressure at the outer
rim of the filter, not the flexible center. No cover
pressure is required to hold the seal (Figure 7-7).
5. Install the cover on the air cleaner body with the two
arrows pointing up. Secure the cover with the latches.
6. Check all connections and ducts for an air tight fit. Make
sure that all clamps, bolts, and connections are tight.
Check for holes in piping. Leaks in the air intake system
may send dust directly to the engine.
Element Cleaning
Washing in a water-detergent solution or blowing out with
compressed air are two accepted methods for cleaning the
element of the air cleaners. If the element contains
substantial amounts of soot or oil fumes, washing in water
works better than compressed air. If the contaminant is found
to be mostly loose dust, either method works equally well.
Elements that are cleaned with compressed air can be put
back into service immediately. Elements cleaned by washing
must be dried before returning them to service.
NOTE: Some elements are partially covered by a plastic
sleeve with fins. The covered portion can be
cleaned with water or air without removing the
sleeve. Use a stiff fiber (not wire) brush to remove
oil and grease deposits from the sleeve and fins.
Never remove the sleeve and fins from the
element.
CAUTION
Never service the air cleaner while the engine is running.
