Kohler Air Cleaner (Secondary)

NOTE: The Kohler Air Cleaner should only be ser- viced more often than a yearly interval if there are indications that the Donaldson Radialseal™ (prima- ry) has failed.

• Foam Precleaner

An oiled, foam precleaner surrounds the paper ele- ment of the Kohler engine air cleaner system. Clean and re-oil the foam precleaner yearly or more often in dusty or dirty conditions.

1.Unscrew the air cleaner cover mounting nut and remove the air cleaner cover.

2.Remove the foam precleaner by sliding it off the paper element.

IMPORTANT: Replace the foam precleaner if necessary. Use ONLY Kohler replacement part #24-083-02.

3.Wash the foam precleaner in warm water with detergent. Rinse thoroughly and squeeze out excess water (do not wring). Allow the preclean- er to air dry.

4.Saturate the foam with clean engine oil. Squeeze to distribute and remove excess oil.

5.Reinstall the precleaner by sliding it over the pa- per element.

6.Reinstall the air cleaner cover and mounting nut.

• Paper Element

The Kohler engine uses a dry, high density paper air filter element. Check the element (located under the foam precleaner) yearly or more often in dusty or dirty conditions. Replace the element if it is dirty, bent, or damaged.

IMPORTANT: Use ONLY Kohler part #47-083-03. Aftermarket filters may not seal properly or filter ef- ficiently.

IMPORTANT: Kohler does not recommend clean- ing the paper element and reinstalling. DO NOT wash the element or use pressurized air to clean as this will damage the element. NEVER apply oil to the paper element.

1.Unscrew the air cleaner cover mounting nut and remove the air cleaner cover and rubber seal on the air cleaner stud.

2.Remove the foam precleaner from the paper el- ement. Replace if necessary.

3.Unscrew the element cover mounting nut and remove the element cover and the paper ele- ment.

4.Use a bright light and inspect the inside of the element for dirt or damage. Check very careful- ly for pin holes or other damage that will allow dirt to leak through the paper. Replace the ele- ment if necessary.

5.Check the condition and resilience of the ele- ment gaskets. If the gaskets have hardened or cracked or if there is evidence of a gasket not seating evenly, replace the element.

6.Check the air cleaner base plate. Make sure it is secure and not bent or damaged. Check the condition of the rubber seal on the air cleaner stud. Also, check the element cover for dam- age. Replace any damaged components.

7.Reinstall the paper element, cover, mounting nut, and foam precleaner. Tighten, but do not overtighten, the mounting nut (tighten 1/2 to 1 turn after contacting the cover).

NOTE: A light coating of grease on the filter gaskets is recommended to enhance sealing and prevent dust leaks.

8.Check the security of the element. Make sure the element is positioned properly and sealed tightly against the air cleaner base plate and el- ement cover.

9.Reinstall the rubber seal on the stud, the air cleaner cover, and mounting nut.
