3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until
all traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the precleaner
to air dry.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner into the outer cover.
6. Install the air cleaner cover and secure with the
two knobs.
7. When precleaner replacement is necessary, order
Kohler Part No. 20 083 03-S.
Paper Element Service
Check the paper element annually or every 25 hours
of operation (more oen under extremely dusty or
dirty conditions). Clean or replace the element as
necessary. Replace the air cleaner element annually or
every 100 hours.
1. Remove the air cleaner cover and the precleaner
(if so equipped), service as required.
2. Remove the air cleaner element with the integral
rubber seal.
3. Gently tap the pleated side of the paper element
to dislodge dirt. Do not wash the paper element
or use pressurized air, as this will damage the
element. Replace a dirty, bent, or damaged
element with a genuine Kohler element. Handle
new elements carefully; do not use if the rubber
seal is damaged.
4. Clean all air cleaner components of any
accumulated dirt or foreign material. Prevent any
dirt from entering the throat of the carburetor.
5. Install the air cleaner element with the pleated
side out and seat the rubber seal onto the edges
of the air cleaner base.
6. Reinstall the precleaner (if so equipped), into
the upper section of the air cleaner cover. Make
sure the hole in the precleaner is aligned with the
upper mounting knob. See Figure 4-1.
7. Reinstall the air cleaner cover and secure with the
two knobs.
8. When element replacement is necessary, order
Kohler Part No. 20 083 02-S.
Inspect Air Cleaner Components
Whenever the air cleaner cover is removed, or the
paper element or precleaner is serviced, check the
following areas/components:
Outer Air Cleaner Cover - Make sure the air cleaner
cover is in good condition, not cracked, damaged, or
missing a retaining knob, which can affect the sealing
ability of the air cleaner element.
Air Cleaner Base - Make sure the base is properly
secured and not cracked or damaged. Since the
air cleaner base and carburetor are secured to the
intake port with common hardware, it is extremely
important that the fasteners securing these
components are tight at all times. The air cleaner
base also provides the mounting points for the air
cleaner cover retaining studs. Make sure the bosses
are not cracked, broken or damaged, and the studs are
properly secured.
Before reinstalling an air cleaner base that has been
removed, make sure the metal bushings in the base
mounting holes are present. See Figure 4-2. The
bushings prevent damage to the base and maintain
the proper mounting torque.
Figure 4-2. Bushings in Air Cleaner Base.
Breather Hose - Make sure the hose is not cracked or
damaged, and aached to both the air cleaner base
and valve cover.
NOTE: Damaged, worn, or loose air cleaner
components can allow unfiltered air into the
engine causing premature wear and failure.
Tighten or replace all loose or damaged
components.
