Engine air filter

Perform engine air filter maintenance per the Service Interval chart on
page 11-8.
A specially designed dry filter is standard equipment on the Super Mini
Z tractors and supplies clean combustion air to the engine. Fig. 11-12
Recommended service procedure
Many engine failures can be attributed to improper air cleaner
servicing. Ingested dust and dirt will cause cylinder, piston and bearing
damage in a few hours. "Dusted" engines will result from:
1. Overservicing the air filter element.
2. Improper installation.

3. Damaged filter, seals or canister.
4. Incorrect air filter element size.
5. Use of poorly designed aftermarket air filter elements.
Air cleaner servicing is an inexpensive maintenance check that can
prevent costly non-warrantable premature engine damage.
Overservicing
Overservicing occurs when an air filter element is removed for cleaning
or replacement before it is necessary. Each time the filter is removed a
small amount of dirt and dust could fall in the intake system. This
accumulated dirt can cause a dusted engine. It only takes a few grams of
ingested dirt over the normal service life of an engine to cause a dusted
engine.
Do not clean element, replace with a new element only. Cleaning
used air filter elements, through improper cleaning procedures, can get dust
on the inside of the filter causing dirt ingestion and engine failure.
It is important to note that whenever an air filter element is cleaned by
any method, the person or company performing the cleaning assumes
responsibility for the integrity of the filter from then on. The Donaldson
warranty for air filters expires upon cleaning or servicing in any
manner because the condition of the filter after servicing is completely
out of their control. Therefore, on a dust ingested engine failure, there
will be no warranty consideration if the air filter element has been
cleaned or serviced in any manner.
A partially dirty air filter element works better than a new element.
Therefore, a dirty filter element is not bad for the engine unless it is
excessively restricting the air flow and engine performance is affected. The
reason is simple. The media in the filter must be porous to allow air to pass
through it. When dirty air passes through the filter, the dirt plugs some of
the holes in the media and actually acts as part of the filter media. When
the next round of dirt enters, the first dirt helps filter out even smaller
particles making the filter more efficient at stopping dirt from entering the
engine. This is referred to as barrier filtration.
Of course, at some point the filter media becomes too clogged to allow
air to pass.
The mowing conditions will determine the frequency of air filter
element changing.
Improper installation of an air filter element
Dust must not leak past the seals on each end of the air filter element.
The filter must be aligned within the canister and properly seated for an
effective seal so that no dirt can enter the engine.
Damaged filter, seals or canister
Never bang or bump the filter element against the tire or any solid
object, as dust and dirt particles will be forced through the media causing
continual passing of dirt into the engine. Visually inspect the outside of the
air cleaner canister periodically for external damage and replace if
necessary.
