Air Cleaner Maintenance

• 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 requires it or every 400 hours
(more frequently in extremely dusty or 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.
Servicing the Air Cleaner
Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air
cleaner body.
Service the air cleaner filters when the air cleaner
indicator (Figure 45) shows red or every 400
hours (more frequently in extremely dusty or dirty
conditions). Do not over-service the air filter.
Be sure that the cover is sealing around the air
cleaner body.
1. Pull the latch outward and rotate the air cleaner
cover counterclockwise. Remove the cover
from the body (Figure 45). Clean the inside of
the air cleaner cover.

2. Before removing the filter (Figure 46), 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
