Clean Air Intake/Cooling Areas
To ensure proper air circulation, make sure the air
intake screen, radiator, cooling fins, and other external
surfaces of the engine are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty, dirty conditions), remove the upper
blower housing assembly. Clean the cooling fins of the
radiator, external surfaces, and the air intake screen
and blower housing assembly as necessary. The
screen assembly may also be separated from the
upper blower housing to permit more thorough
cleaning if required. See Figures 18, 19, and 20. Make
sure all parts are reinstalled before starting the engine.
If the screen assembly was separated from the blower
housing, push the upper retaining clips into the locked
position.
Clean the cooling fins of the radiator with a soft brush
or blow out using clean, compressed air. See Figure
22. Do not use a high pressure washer to clean, to
avoid damaging the cooling fins.
NOTE: Operating the engine with a blocked air intake
screen, dirty or plugged radiator cooling fins,
and/or cooling shrouds removed, will cause
engine damage due to overheating.
3. Unhook the element retaining strap and remove
the paper element from the air cleaner base. See
Figure 21.
Figure 21. Unhooking Retaining Strap.
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
new genuine Kohler element. Handle new
elements carefully. Do not use if the sealing
surfaces are bent or damaged.
5. Clean the air cleaner base area, upper blower
housing, and screen assembly of any debris
accumulation. If required, the screen assembly
may also be separated from the blower housing by
unsnapping it from the underside. See Figures 18,
19, and 20. Check all parts for wear, cracks, or
damage. Replace any damaged components.
6. Install the new paper element, Kohler Part No.
66 083 01-S and secure with the element retainer
strap.
7. Install the precleaner over the paper element,
outside the element retaining strap.
8. Reinstall the upper blower housing and screen
assembly. Secure with the four retaining straps.
