1. The inlet must be located away from heavy dust concentrations.
2. Check the inlet location; make it sure that exhaust gases are directed above and away from the air cleaner inlet. Soot from exhaust is a prime enemy of paper filters.
3. The air supply to the air cleaner must be must be of adequate size and unrestricted.
4. Check the air cleaner to make sure it is the correct size for the engine.
5. The air cleaner element must be new when installed. It is not good practice to clean air cleaner, it could be damaged in this process.
6. Make sure the clean air ducting after the air cleaner is unrestricted and it is of adequate size.
7. Check the service indicator for damage, working lock-up function, and correct calibration per engine manufacturers recommendation.

 

1. Make sure the element has not been damaged in handling. Examine for dents
and holes.
2. Be certain that all gasket are sealing. Examine for dust trails, which indicate
leaks. Check to be sure wing nut is tight.
3. Examine the clean air transfer tubing for cracks, loose clamps, or loose
flange joints.
4. Check air compressor connections (if used) to be certain these are leak free.
5. Check ether fittings (if used) to be certain no contaminants are entering
the engine through these connections.

 

IMPORTANT STEPS TO FOLLOW
(Every time an air cleaner element is replaced)
Note: Be sure to empty the pre-cleaner bowl or cup as required

1. Remove the old element as gently as possible

Carefully remove the dirty element, until you get it clear of the housing. Accidentally
bumping it while still inside will result in dust and dirt contaminating the
clean side of the filter housing, before the new element has chance to do its
job.

2. Always clean the inside of the housing carefully

Dirt left in air cleaner housing spells trouble for your engine. Always use
a clean damp cloth to wipe every surface clean. Check it visually to make sure
it is clean before putting in a new element.

3. Always clean the gasket sealing surfaces of the housing.

An improper gasket seal is one of the most common causes of engine contamination.
Make sure that all hardened dirt ridges are completely removed, both on the
bottom and top of the cleaner.

4. Check for uneven dirt patterns on your old element

Your old element is a valuable clue to dust leakage or gasket sealing problems.
A pattern on the element clean side is a sign that the old element was not firmly
sealed or that a dust leak exists. Make certain the cause of that leak is identified
and rectified before replacing the element.

5. Press your fresh gasket to see if it springs back

Make sure your new element is made with a highly compressible gasket that springs
right back when your finger pressure is released. A quality gasket is one of
the most important parts of the element.

6. Make sure the gasket is seating properly

If you don’t feel the gasket is seating evenly for perfect seal, then
you don’t have adequate protection. Rechecking to see if the sealing surface
in the housing is clean, or if the element is the correct part number. It may
be the wrong size for the housing.

 WARNING!

 

1. Don’t remove element for inspection

Such a check will always do more harm to your engine than good. Ridges of dirt
on the gasket sealing surface can drop on the clean filter side when the gasket
is released. Stick to the manufacturers recommended schedule. If you have fitted
a restriction indicator, use this as a guide. If you are in any doubt about
the reliability of the indicator, fit a new one.

2. Never rap an element to clean it-except to
destroy it

Rapping hard enough to knock off dust often damages the element and destroys
your engine protection. Deeply embedded dirt is never released by tapping. It
is always safer to keep operating until you can change to a fresh filter.

3. Never judge your element’s life by looking
at it

While carbon contamination is not visible to the eye, you can’t see the
dirt that’s embedded deep within the filter paper. The most cost effective
way for lowest filter maintenance costs and best engine performance is to fit
a restriction gauge.

4. Never leave an air cleaner open longer than
necessary

Your open air cleaner is a direct entry to your engine. If the cleaner is not
going to be change or reassembled immediately, cover the opening. The only way
to be sure nothing got in is to be sure nothing gets in.

5. Don’t overlook a worn or damaged gasket
in the housing

If your cleaner has a cover gasket, replace it with a new one. Always check
to be sure no piece of the old gasket remains in the housing and that the gasket
in not worn. If your filter model calls for a new gasket with each use, never
reuse the old one.

6. Don’t use a dented or bunched filter
element

Never install a dented or punctured element, because it cannot protect against
contamination. A dent can make a firm seal impossible or can indicate damaged
media. An element with bunched pleats reduces engine power and increases fuel
costs.

7. Never use a warped cover on a housing

Replace with a new cover as soon as possible. A warped or damaged cover cannot
make a proper seal. Also check to make sure there is no damage to the air cleaner
housing that could cause a leak.

8. Never substitute an incorrect element model
number

Elements may look almost identical but can differ by a fraction of an inch in
length—a difference that makes a firm seal impossible. You’re always
better off using the dirty element until you can get the correct model.
