AIR INTAKE
I
AIR CLEANER SERVICE .
An air cleaner must be maintained in proper condition to insure satisfactory performance and
prolonged engine life. Operating with an !‘overrich” fuel mixture caused by a poorly serviced, clogged
air cleaner leads to formation of harmful sludge deposits.
An inadequate element or improperly
installed air cleaner permits entrance of dirt which can wear out piston rings in a very short time.
The service intervals stited for air cleaners are for good clean conditions--service cleaners more
frequently under dusty or dirty conditions (even daily,
if extreme conditions warrant this). Dry and oil
bath type cleaners are used
--carefully follow instructions for type in use. A flame arrestor type
cleaner is used on many marine models.
DRY TYPE AIR CLEANER
Replace-element after 100-200 hours if operating under gdod clean air conditions--sooner in dusty,
dirty conditions. Use only genuine kohlerreplacement elements of correct part number.
Every 50 hours (or 3 months), remove element and lightly tap rubber rim against flat surface to
dislodge any loose dust from surface.
Replace element if it has too many dark spots or extensive dark
area as this indicates dirt trapped in the filter material. Do not wash dry element in any liquid or
attempt to clean element with air hose as this will ruin or rupture the paper fiber material.
When
handling element, avoid crushing material or bending element as this co&d allow unfiltered air to
enter the engine
--note a’ir flow shown in the figure below.
When installing a new or serviced element, make sure rubber gasket surfaces are flat against the
filter base and cover
--secure wing nut (with washer in place when used) finger tight--washer is not
required with plastic type wing nuts.
