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

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,
(Figure 41).

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.
