To Service
Every 250 hours of operation (more often under
extremely dusty or dirty conditions), replace the
paper element and check the inner element. Follow
these steps.
1. Unhook the two retaining clips and remove the
end cap from the air cleaner housing.
2. Pull the air cleaner element out of the housing.
See Figure 4-13.
4. Do not wash the paper element and inner
element or use compressed air, this will damage
the elements. Replace dirty, bent or damaged
elements with new genuine Kohler elements as
required. Handle the 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, followed by the
outer element. 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 4-12.
Removal
1. Remove the upper valve cover screws on each
side, securing the main bracket, and loosen the
hose clamp on the adapter inlet, or remove the
adapter mounting screws.
2. Lift the entire air cleaner assembly off the engine.
Disassemble or service as required.
Installation
1. Install the main mounting bracket with the center
section up and the cutout around the carburetor,
aligning the mounting holes with the four upper
valve cover holes.
2. Install and torque the four valve cover mounting
screws to specified torque value.
3. Reconnect the hose to the adapter and tighten the
clamp, or install a new adapter gasket (if the
adapter was separated from the carburetor), and
torque the mounting fasteners to
7.3 N·m
(65 in. lb.) .
NOTE: Adapter configurations may vary
depending on engine and application
involved. Two adapters are shown in
Figure 4-14.
Figure 4-13. Removing Elements.
3. After the 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.
