Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours
• 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 before 200 hours if the
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.
• 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 42).

2. 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 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 the primary filter is
removed.
3. 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.
4. 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.
5. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
6. Secure the latches (Figure 42).
