Section 4
Air Cleaner and Air Intake System
On these, air is drawn in around the bottom of the
cover, or from the blower housing, rather than from
slots. The fl at base allows debris to be brushed away
before the paper element is removed. All types can
use either the standard size element or a higher, extra
capacity paper element.
The original type uses a separate cover retaining
knob which has to be turned completely off to remove
the cover. With the later style, the knob snaps into
the cover and is turned counterclockwise until it
disengages the stud. Other differences are pointed out
in the exploded views.
Service
Check the air cleaner daily or before starting the
engine . Check for and correct any buildup of dirt and
debris, and loose or damaged components.
NOTE: Operating the engine with loose or damaged
air cleaner components could allow unfi ltered
air into the engine, causing premature wear
and failure.
Precleaner Service
If so equipped, wash and reoil the precleaner every 25
hours of operation (more often under extremely dusty
or dirty conditions).
1. Remove the precleaner from the paper element.
2. 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.
3. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
4. Reinstall the precleaner over the paper element.
5. Reinstall air cleaner cover and tighten the
retaining knob.
Paper Element Service
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), check the paper
element. Clean or replace the element as necessary.
1. Remove the wing nut and air cleaner element.
2. Remove the precleaner (if so equipped) from the
paper element.
3. Gently tap the fl at 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 sealing
surfaces are bent or damaged.
4. Inspect the rubber seal (sleeve) on the stud. If it
is worn, damaged, or questionable, replace it. A
new seal comes packed with each replacement
element.
5. Reinstall the precleaner, paper element, wing
nut, and air cleaner cover. Make sure the knob is
tightened securely.
Inspect Air Cleaner Components
Whenever the air cleaner cover is removed, or the
paper element or precleaner are serviced, check the
following areas/components:
Air Cleaner Base - Make sure the base is 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 nuts securing these components are tight at all
times.
Before reinstalling an air cleaner base that has been
removed, make sure the metal bushings in the base
mounting holes are present. See Figure 4-3. The
bushings prevent damage to the base and maintain
the proper mounting torque.
Figure 4-3. Bushings in Air Cleaner Base.
Breather Tube - Make sure the tube is attached to
both the air cleaner base and valve cover.
