3. Check the condition of the inner safety element. It
should be replaced whenever it appears dirty,
typically every other time the main element is
replaced. Before removing it from the housing,
clean the area around the base of the inner
element, so dirt does not get into the engine. See
Figure 4-6.
Figure 4-6. Removing Cylindrical Inner Element.
4. The elements must be replaced when dirty. Do
not attempt to clean the elements with
pressurized air, or other means, as the elements
will be ruined. Handle new elements carefully;
do not use if the sealing surfaces are bent or
damaged. Replace any damaged or questionable
components.
5. If it is being replaced, install the new inner
element, Kohler Part No. 25 083 04-S, followed by
the canister outer element; Kohler Part No.
25 083 01-S. Slide each fully into place in the
housing.
