Air Cleaners
General
These engines are equipped with one of three air
cleaner configurations; the standard dual-element air
cleaner assembly, an optional heavy-duty cyclonic air
cleaner assembly, or a third design which uses an
oiled, solid foam element. The first two styles have a
replaceable, high-density paper element surrounded
by an oiled-foam precleaner. See Figures 4-1 and 4-2.
Servicing information for these two styles is on pages
4.1 through 4.4. The third design does not use a paper
element, just the foam. See Figure 4-14. Servicing
information for the third design is on page 4.5. The
heavy-duty air cleaner assemblies also contain a lower
swirl chamber which separates the dirt particles from
the incoming air for extended service intervals.

Service
Check the air cleaner daily or before starting the
engine . Check for buildup of dirt and debris, along
with loose or damaged components.
NOTE: Operating the engine with loose or damaged
air cleaner components could allow
unfiltered air into the engine causing
premature wear and failure.
