LUBRICATION & SERVICE
SERVICING AIR CLEANER ELEMENT (Figure 17)
Open the hood and remove the air cleaner cup. Remove
the wing nut at end of element and remove the element
from the air cleaner housing.
Washing in water or blowing with compressed air are
the two preferred methods for cleaning. If the element
regularly contains substantial amounts of soot or oil
fumes, washing in water works better than compressed
air. If the contaminant on the element is mostly dust,
either method works well. Elements that are cleaned
with compressed air can be put back into service im¬
mediately. Water cleaned elements must be dried
before they can be used; therefore it is a good practice
to keep an extra element on hand to use while the
washed element is drying.
The filter element is 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.
IMPORTANT:
Do not remove plastic sleeve and fins
from the element.
Cleaning-with Compressed Air
Direct a jet of clean, dry air from the inside of the filter
element, perpendicular to the pleats.
IMPORTANT:
Pressure at air nozzle must not exceed
100 PSI (690 kPa).
Move the air jet up and down along the inside of pleats,
slowly rotating the element, until no more dust is being
removed. Time required is approximately 10 minutes.
IMPORTANT:
Be careful to see that the element is
not ruptured by the nozzle or the air jet. NEVER direct
air jet against the outside surface of filter.
Cleaning with Water
Filter elements can be cleaned by washing with water
and a good non-sudsing detergent. If compressed air is
available, first direct a jet of clean, dry air from the
inside of the filter element. When the loose dust and
soot have been removed, the element is ready to be
washed.
First dissolve the detergent in a small amount of cool
water. Then add warm (approximately 100° F (30° C)
water to get the proper proportions of detergent and
water. Soak the element in the solution for at least 15
minutes. Then agitate the element for about two (2) mi¬
nutes to loosen the dirt.
CAUTION:
Never use gasoline or solvents
to clean elements.
Rinse the element with clean water until the water
coming through the element is clean. Water pressure
from a hose or tap should not be over 40 PSI (276 kPa).
Air-dry the element thoroughly before using.
NOTE:
Mechanized drying methods can be set up;
however, heated air (maximum temperature 180° F (82°
C) must have some circulation. Do not use light bulbs
for drying the element.
Inspecting the Cleaned Filter Element
After cleaning the filter element, using either air or
water, inspect the element for damage. Look for dust
on the clean air side, the slightest rupture, or a dam¬
aged gasket. A good method to detect ruptures in the
element is to select a dark place, place a light inside
the element, and look toward the light from the outside.
Any hole in the element, even the smallest, will pass
dust to the engine and cause unnecessary wear.
INSPECTING AIR INDUCTION SYSTEM
The air induction system should be periodically
checked for parts that may be worn, missing, or dam¬
aged. Hoses, gaskets, and connections particularly
should be checked for possibility of an air leak. Any air
leak that is detected should be corrected before
operating the engine.
REINSTALLING THE FILTER ELEMENT (Figure 17)
Thoroughly clean the inside of the air cleaner housing
before reinstalling the filter element. Be sure the
gasket on the filter element is in good condition; then
install the filter element, tightening with the wing nut.
A gasket must be between the wing nut and filter ele¬
ment and must be in good condition.
IMPORTANT:
Never operate the engine without a
filter element in the air cleaner, and always use
genuine filter elements for maximum protection.
Reinstall the air cleaner cup with the markings
upward, being sure that the cup makes a tight seal.
Close the tractor hood.
IMPORTANT SERVICE INFORMATION
The filter element should be replaced after one year, or
after six cleanings, whichever occurs first.
Store filter elements where they are protected from
dust and potential damage.
Keep spare elements (new or cleaned) on hand to use
while a freshly washed element isdrying.
When replacing filter elements, be absolutely sure that
the proper element is used. Your authorized dealer can
supply you with the proper element.
