Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours (More frequently in
extreme dusty or dirty conditions)
• Check the air cleaner body for damage which could
cause an air leak. Replace it if it is damaged. Check
the whole intake system for leaks, damage, or loose
hose clamps.
• Service the air cleaner at the recommended service
interval or earlier if engine performance suffers due
to extremely dusty, dirty conditions. Changing the air
filter before it is necessary only increases the chance
of dirt entering the engine when the filter is removed.
• Ensure that the cover is seated correctly and seals
with the air cleaner body.
1. Release the latches that secure the air cleaner cover
to the air cleaner body (Figure 59).

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 the outside
of primary 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
you remove the primary filter.
4. Remove and replace the primary filter (Figure 60).
Note: Cleaning the used element may damage the
filter media.

5. Inspect the new filter for shipping damage and check
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.
8. Remove the rubber outlet valve from the cover, clean
the cavity, and replace the outlet valve.
9. 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.
10. Secure the cover latches.
