3. Slacken clamp (6, Fig. 2) and disconnect elbow
(3, Fig. 2) from air cleaner body (1).
4. Remove nuts (16, Fig. 2), lockwashers (15, Fig. 2)
and bolts (14, Fig. 2) securing the air cleaner
assembly to mounting bracket (1, Fig. 2).
5. Remove the air cleaner assembly from the machine
for cleaning.
6. Open clamps (6) and remove from air cleaner
body (1). Open clamp on cap assembly (7) and
remove cap assembly from air cleaner body (1).
7. Blank off air cleaner body (1) outlets with tape or
cardboard. Reach inside body with a compressed air
nozzle or brush and remove dust from the body.
8. Remove all loose dust from air cleaner body (1) and
remove tape or cardboard from body outlets.
Note:
Assembly and installation of the air cleaner
assembly is the reverse of disassembly and removal.
Primary Element
Numbers in parentheses refer to Fig. 1.
Although a paper primary element (2) is used, it is
possible to clean it so that it can be reused. The
number of times one element can be reused depends
on the type of dirt on the element and the care
exercised in cleaning.
The life of a properly cleaned element will be
approximately as long as that of a new element for the
first one or two cleanings. After that, the life of the
element will gradually decrease with each cleaning;
however, it should perform satisfactorily through
approximately six cleanings, providing it does not rupture.
Visually determine the condition of primary element (2)
and choose either the compressed air or washing
method.
1. Release latches (5) on cover assembly (4) and
remove cover assembly from air cleaner body (1).
2. Remove primary element (2) from air cleaner body (1).
3. Using a damp cloth and a suitable solvent, wipe out
all excess dust from air cleaner body (1) and allow to
dry.
4. If the major contaminant on primary element (2) is
light dust, direct a jet of compressed air, not exceeding
6.9 bar (100 lbf/in
2 ), against the pleats of the element.
The air jet should be directed in the opposite direction
of normal operating air flow. Move the air jet up and
down the pleats, holding the air nozzle 25 mm (1.0 in)
away from the pleats, to prevent rupturing the element
with either the nozzle or air jet.
5. In cases where the dust cake on primary element
(2) contains oil or carbon, air will not clean effectively.
Using manufacturers recommended solution and
warm water, not exceeding 48° C (120° F), soak
primary element (2) for fifteen minutes. Element
should be gently agitated to assist cleaning process.
Note: It is possible to modify an old agitator type
washing machine for primary element (2) cleaning. Do
not soak or agitate primary element (2) in the solution
for more than fifteen minutes. Prolonged exposure
softens vertical seams in the element.
6. Rinse washed element thoroughly with a low
pressure stream of water, not exceeding 0.7 bar
(10 lbf/in
2 ), opposite from the normal air flow, until
rinse water runs clear.
7. Air dry primary element (2) thoroughly before
returning it to service. Drying is a slow process which
may be hastened by exposing element to slowly
circulating heated air. Heated air temperature should
not exceed 46
o
C (115
o
F). Drying time can be reduced
to about three hours with heated air. DO NOT use a
light bulb for drying. DO NOT use compressed air on a
wet element.
Note: Replace paper elements after six cleanings or
two years in service, whichever comes first. Mark each
cleaned element to show total cleanings to date.
8. After primary element (2) is thoroughly dried,
inspect for damage or ruptures, especially close to the
end caps. To detect paper ruptures, place a bright light
bulb inside the element and rotate element slowly.
Inspection of element on the outside will disclose any
holes where concentrated light shines through. Even
the smallest hole will pass dust to the engine and may
result in costly engine repairs.
9. Install primary element (2) in air cleaner body (1).
10. Install cover assembly (4) on air cleaner body (1)
and secure with latches (5).
