5. Rinse the filter from the inside out with a
gentle stream of water to remove all dirt and
suds (less than 40 psi [2,76 bar], no nozzle).
If the inside of the element has been contami-
nated with dirty water from the soaking, rinse
from both sides.
6. Dry the filter before reusing. Circulate warm
air at less than 160° F (71 °C). DO NOT use a
light bulb or compressed air to dry the filter.
7. Inspect for holes or tears by looking through
the filter toward a bright light. Check for
damaged gaskets or metal parts. DO NOT
reuse damaged filters.
8. Replace the primary element after six clean-
ings or annually.
9. Continue with next step when necessary.
3. Soak filter in a non-sudsing detergent (such as
FM 1400) for at least 15 minutes. Never soak
more than 24 hours.
4. Swish filter around in the solution to remove
loosened dirt particles.

8B.4.7 Clean or Replace Primary
Element as Required
by Restriction Indicator
All air cleaner manufacturers agree that attempting to
clean or wash an element increases the chance for
element damage. It is highly recommended that you
consider the value of cleaning an element against the
risks which could lead to engine damage. Adopt the
policy that all elements should be replaced with new and
not cleaned.
Careful cleaning or washing, if done correctly, can
extend the life of an element. But you must realize that
each time an element is cleaned the dirt holding
capacity is reduced and the risk of dirt reaching the
clean side of the filter is increased. Filters should never
be washed more than six times or retained for more
than one year’s service, whichever comes first.
If you wash an element, it is recommended that you use
a non-sudsing detergent that dissolves combustion
residues without damaging the filter media. One such
detergent that is specifically formulated for this purpose
is FM 1400. This cleaner contains biodegradable
synthetic detergents and is environmentally safe. It is
marketed by Filter Service Corp., 2105 W. Apache,
Farmington, New Mexico, 87401, Telephone (505) 326-
1127.
1. Remove the air cleaner cover wing nut, cover,
and primary element, Fig. 8A.6.
2. Remove loose particles from the filter with
compressed air (maximum 30 psi [207,0 kPa])
or water hose (maximum 40 psi [2,76 bar]
without nozzle). Rotate and apply air pressure
from the inside of the element.
8A.5.8 Install a New Safety Element
With Every Third
Primary Element
1. An inner safety element should never be
washed or reused. Always install a new
element. Replace safety elements after every
third primary element change. DO NOT
remove a safety element until you have
thoroughly cleaned the inside of the air
cleaner canister. This will prevent dirt, which
could damage the engine, from entering the
induction manifold.
