Filter Element Replacement
1. Loosen bolts and remove the access ladder.
2. Lift the clips (1, Figure 7-8) securing the cover to the air
cleaner body and remove the cover.
3. Remove Primary Filter from the Air Cleaner and inspect
for foreign material and marks of dust. Replace as
necessary
4. Remove Secondary Filter (not shown) from behind the
Primary Filter. Replace Secondary Filter every third time
the Primary Filter is changed.
5. Thoroughly clean the sealing surface and inside of the
air filter housing. Inspect all parts of the intake system
and air cleaner.
6. Place the cover back on the air cleaner housing and
secure with clips (1).
7. Check all connections and ducts for an air tight fit. Make
sure that all clamps, bolts, and connections are tight.
Check for holes in piping. Leaks in the air intake system
may send dust directly to the engine.
Element Cleaning
It is not recommended that filter elements be cleaned.
Cummins and most other manufacturers will not warrant a
cleaned air filter.
Air Cleaner Body
Before installing the filter element, remove foreign material
(leaves, lint or other foreign matter) that may have collected
inside the air cleaner body. Inspect the inside of the body for
dents or other damage that would interfere with air flow or
with the fins on the element or inside the body. Repair any
body dents, being careful not to damage the sealing
surfaces. Be sure to clean the sealing surface of the outlet
tube and the inside of the outlet tube, taking care not to
damage the sealing area on the tube.
Pre-cleaner
The pre-cleaner (1, Figure 7-9) prevents large debris from
entering the air cleaner and should be cleaned periodically,
especially when working in severe dust conditions. Remove
the top half of the pre-cleaner by releasing the two latches on
the sides of the pre-cleaner. Remove all debris from inside
pre-cleaner and reassemble.
Evacuator Valve
Evacuator valve (2, Figure 7-9 and Figure 7-10) is designed
to automatically expel loose dust and dirt from the air cleaner
body, thus lengthening the element service life. The valve
lips must point straight down and be kept free of debris to
operate effectively. Mud and chaff can lodge in these lips
periodically and hold them open during engine operation.
Check the condition of the valve and lips frequently and keep
them clean. The valve lips should be open only when the
engine is shut down, or running at low idle speed. If the valve
is turned outside in, check for a clogged air cleaner inlet.
Malfunction of this valve does not reduce the air cleaner
CAUTION
Never service the air cleaner while the engine is running.
