Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours (Service it more
frequently in extremely dirty or dusty
conditions.)
Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
Service the air cleaner filter at the specified interval.
Changing the air filter before it is necessary only
increases the chance of dirt entering the engine when
the filter is removed.
Important: Be sure the cover is seated correctly
and seals with the air cleaner body.
1. Release the latches securing the air cleaner cover to
the air cleaner body (Figure 44).

2. Remove the cover from the air cleaner body.
3. Before removing the filter, use low pressure air (40
psi (276 kPa), clean and dry) to help remove large
accumulations of debris packed between outside
of the filter and the canister. Avoid using high
pressure air which could force dirt through the
filter into the intake tract.
This cleaning process prevents debris from migrating
into the intake when the filter is removed.
4. Remove and discard the filter (Figure 44).

3. Filter
Cleaning of the used element is not recommended
due to the possibility of damage to the filter media.
5. Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body. Do not
use a damaged element.
6. Insert the new filter by applying pressure to the outer
rim of the element to seat it in the canister. Do not
apply pressure to the flexible center of the filter.
7. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the
cover, clean the cavity and replace the outlet valve.
8. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
9. Secure the latches.
