Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 400 hours (Service the air cleaner
earlier if the air cleaner indicator shows
red. 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 only when the service indicator
(Figure 52) requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the engine
when the filter is removed.
Important: Make sure that 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

2. Air-cleaner-cover latch
2. Remove the cover from the air-cleaner body.
3. Before removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations of
debris packed between outside of the filter and the
canister.
Important: Avoid using high-pressure air which
could force dirt through the filter into the intake
tract.
Note: This cleaning process prevents debris from
migrating into the intake when the filter is removed.
4. Remove and replace the filter
Note: 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.
Important: 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.
Important: 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 o'clock
to 7 o'clock when viewed from the end.
9. Secure the latches.
