Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 400 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 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.

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 (Figure 54).
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.
