Service Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions) replace the paper
element.
1. Loosen the cover retaining knob and remove the
cover.
2. Remove the element cover nut, element cover, and
paper element with precleaner.
3. Remove the precleaner (if so equipped) from the
paper element. Service the precleaner as
described above.
4. 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.
5. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent
or damaged. Also, check the element cover for
damage or improper fit. Replace all damaged air
cleaner components.
NOTE: If any loose dirt or debris fell on the air
cleaner base when the element was
removed, carefully remove it and wipe
the base clean. Be careful that none of it
drops into the intake throat. Check the
condition of the rubber seal on the air
cleaner stud. If the condition is
questionable in any way, replace it with
the new seal packaged with the
replacement element.
6. Reinstall the paper element, precleaner, element
cover, element cover nut, and air cleaner cover.
Secure cover with the cover retaining knob.
7. When element replacement is necessary, order
genuine Kohler parts.

3. After the main element is removed, check the
condition of the inner element. It should be
replaced whenever it appears dirty, typically
every other time the main element is replaced.
Clean the area around the base of the inner
element before removing it, so dirt does not get
into the engine.
4. Do not wash the paper element and inner element
or use pressurized air, this will damage the
elements. Replace dirty, bent or damaged
elements with new genuine Kohler elements as
required. Handle new elements carefully; do not
use if the sealing surfaces are bent or damaged.
5. Check all parts for wear, cracks, or damage.
Replace any damaged components.
6. Install the new inner element, Kohler Part No.
25 083 04-S followed by the outer element, Kohler
Part No. 25 083 01-S. Slide each fully into place in
the air cleaner housing.
7. Reinstall the end cap so the dust ejector valve is
down and secure with the two retaining clips.
See Figure 13.
