Paper Element
Every 1 00 operating hours (more often under ex-
tremely dusty or dirty conditions) check the paper
element. Replace the element as follows:
1 . Remove the precleaner (if so equipped), ele-
ment cover nut, element cover and paper ele-
ment.
2. Replace a dirty, bent or damaged element with a
new genuine Kohler element. Handle new
elements carefully; do not use if surfaces are
bent or damaged.
NOTE: Do not wash the paper element or use
compressed air as this will damage the element.
3. Reinstall the paper element.
4. Install the precleaner (cleaned and oiled) over
the paper element.
5. Install the air cleaner cover and wing nut.
Tighten wing nut. Make sure element is sealed
tightly against air cleaner base.

Inspect Air Cleaner Components
Whenever the air cleaner cover is removed, or
when servicing the paper element or precleaner,
check the following components:
1 . Air Cleaner Base - Make sure it is secured
tightly to carburetor and is not bent or dam-
aged.
2. Element Cover and Element Cover Nut - On
K181 New Look engines only, make sure ele-
ment cover is not bent or damaged. Check
that element cover nut is secured tightly to
seal element between air cleaner base and
element cover. Tighten nut to 50 in. lb.
torque. Refer to Figure 5-2.
3. Breather Tube - Make sure it is sealed tightly
in the air cleaner base and breather cover.
NOTE: On Model K181 New Look engines of cer-
tain specifications, the element cover may contact
the breather tube, making it impossible to maintain
crankcase vacuum. To prevent this problem, cut
the end of the breather tube that protrudes
through the air cleaner base at approximately a 45
degree angle.
