SERVICING FARR DRY-TYPE AIR CLEANER
(see Figure 6)
1. For the tube style, loosen the nuts and remove the
moisture eliminator or the pre-cleaner. For the pleated-
paper style, remove the straps.
2. Remove the dirty element.
For the tube style, insert fingers in the element openings
(see Figure 5). Loosen all four corners one at a time by
pulling straight out. It may be necessary to break the
seal along the edges of the element. After the seal has
been broken, pull the element straight out and slightly
up so it clears the sealing edge of the body.
3. Wipe the body clean. If extremely dirty, the pre-
cleaner, the moisture eliminator, or the inlet screen can
be cleaned with high-pressure water or steam.
4. Inspect the dirty element for soot or oil. Soot indicates
engine exhaust leaks or exhaust "blow-back". If the
el,ement appears oily, check for escap, ing fumes from the
cra'nkcase breathers.
5. Discard the element;
do not clean and reuse
it.
6. Inspect the new element for damage. Do not use a
damaged element.
7. Assemble the new element to the body. For the tube
style, hold the element in the same manner as when it
was removed (see Figure 5). Insert the element in the
housing; avoid hitting the element tubes against the
body.

8. The air cleaner requires no separate gaskets or seals;
therefore, exercise care to ensure that the element seal
seats squarely within the body. Firmly press all edges
and corners of the element to effect a positive seal
against the seal flange in the body. DO NOT pound or
press on the center of the element.
9. Assemble the pre-cleaner or moisture eliminator
squarely against the housing.
For the tube style, tighten the wing nuts evenly using a
criss-cross, corner-to-corner pattern. Tighten the nuts
hand tight and make two more turns with a small
wrench. If flanged Iocknuts are used, torque them to 70
in.-Ibs.
For the pleated paper style, assemble the straps to the
housing.
