Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours (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.
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. Remove the knobs securing the rear screen to the
frame (Figure 29). Remove the screen.

3. Remove the cover from the air cleaner body. 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 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 primary filter is removed.
4. Remove and replace the primary filter.
Cleaning of the used element is not recommended
due to the possibility of damage to the filter media.
Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body. Do not
use a damaged element. 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.
5. 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.
6. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
7. Secure the latches And replace and secure the rear
screen.
