POWER UNIT AIR CLEANER MAINTENANCE
Primary Dry Air Cleaner Service Instructions
Proper air cleaner servicing will result in maximum engine protection against the ravages of
dust. Proper servicing will save you time and money by increasing filter life and dust clean
-
ing efficiency. Two of the most common problems of air cleaner service are:
A. Over Servicing - New filter elements increase in dust cleaning efficiency as dust
builds up on the media. DON'T BE FOOLED by filter appearance, it should look dirty.
Use a restriction indicator to monitor filter life.
B. Improper Servicing - Your engine is highly vulnerable to abrasive dust contami-
nants during the servicing process. The most common cause of engine damage is
careless servicing procedures. By following the 7 steps shown, you can avoid unnec-
essary dust contamination to the engine.
1. Remove the old element as gently as possible to prevent dropping dirt/dust into the
housing.
2. Always carefully clean the inside surface of the housing with a clean damp cloth before
putting in a new filter.
3. Always clean the gasket sealing surfaces of both the top and bottom of housing of hard-
ened dirt ridges.
4. Check for uneven dirt patterns in your old filter element for valuable clues to dust leak-
age or gasket sealing problems. A pattern on the element clean side is a sign the filter
element was not firmly sealed or that a dust leak exists. Repair any suspicious areas
before installing a new filter.
5. Check the new gasket for flexibility to spring back when pressure is applied and re-
leased. A quality gasket is one of the most important parts of the filter.
6. Make sure the gasket is seating evenly and the sealing surface in the housing is clean.
Be sure to use the correct filter model. If the filter element is too short for the housing, it
is the wrong model.
7. Check connections and ducts for air tight fit. Any leaks mean dirt is directly entering your
engine.
Important "Don'ts" To Remember About Air Cleaner Servicing
DON'T remove element for inspection, any disturbance can cause contamination or leaks
in the gasket. Use a restriction indicator and change filter when needed.
DON'T try to clean the old filter by rapping to knock out dust. Always replace with a new
filter.
DON'T judge your element's life by looking at it. A dirty-looking filter may still have plenty
of life left. For lowest filter maintenance, follow a restriction gauge.
