4. Unnecessary and improper
cleaning of the element may con-
tribute to introducing dust into the
engine.
5. If the filter element has been
washed, it must be completely dry
before it is reused.
6. Check all air intake hoses
for tightness. Replace hoses which
are cracked or appear question-
able.
7. Avoid imitation parts. Use
only genuine Massey-Ferguson re-
placement filter elements.
To clean the element, proceed as fol-
lows:
1. Turn the knurled knob counterclock-
wise and remove the holding bracket. Then
withdraw the filter element.
2. Use a clean damp cloth and care-
fully wipe the inside of the housing and the
element retaining bracket to remove any dust
or foreign matter present. Make sure rub-
ber unloading valve is completely open and
clean.
3. Determine if air cleaner element is
still serviceable and may be cleaned and
reused. MAKE SURE THE ELEMENT IS
IN GOOD PHYSICAL CONDITION BEFORE
CONSIDERING CLEANING IT. If rubber
seal on end of element is damaged, or if
metal canister is dented or damaged, the el-
ement must be replaced regardless of how
old it is or how many times it has been
cleaned.
4. Clean the outer element. Use com-
pressed air to back-flow element. This pre-
liminary cleaning will remove the loose dust,
making washing easier.
Prepare solution (MF 1900 726 Ml) ac-
cording to directions on the carton.
Soak element in solution for 4 hours , re-
taining a temperature of 120° to 1500 F . for
most effective cleaning.
Agitate element, then rinse both inside
and outside surfaces of element with clean
water from a hose. Continue until drain
water is clear.
Inspect element for pin holes, pleat dam-
age or ruptures that may have occurred be-
cause of careless handling.
NITTE: To avoid any operating de-
lay while the dirty element is being
washed and dried, it is recom-
mended that a spare element be
kept on hand as an immediate re-
placement part.
5. After cleaning, place a light bulb in-
side the element and carefully check the
element for ruptures or other damage. For
best results, do this in a darkened area
0
Inspection of the element on the outside will
then disclose any small holes or major rup-
tures. ANY HOLE IN THE FILTER ELE-
MENT; EVEN THE SMALLEST; WILL AL-
LOW DUST TO PASS INTO THE ENGINE
AND
CAUSE INCREASED ENGINE WEAR.

6. Carefully install filter element into
air cleaner, then install the holding bracket
and tighten the knurled knob clockwise by
hand until it is tight. As a double check, at-
tempt to rotate the element by hand. If the
element can be rotated, it is improperly in-
stalled or the knurled knob is not tight
enough.
Replacing Inner Filter Element
To replace the inner filter element, fol-
low the procedures for removing the outer
filter element, then remove the nut holding
the inner element and carefully remove the
element.
Use a damp cloth and carefully wipe
clean the housing and bracket to remove any
dust or foreign matter present. Install new
filter element and tighten nut until filter el-
ement cannot be rotated by hand. · Install a
clean, or new, outer filter element.
