Engine air filter
Perform engine air filter maintenance per the scheduled maintenance chart. See “SERVICE AT
INTERVALS INDICATED” on page 10-20.
A specially designed dry filter is standard equipment on the Hustler Z and Super Z tractors and supplies
clean combustion air to the engine "FIG. 39".
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
