2.
Inspect all parts of the intake system and air cleaner. Be
sure to clean the sealing surface of the outlet tube and
the inside of the outlet tube.
3.
Install the element into the air cleaner body as follows:
a.
INSPECT THE FILTER FOR DAMAGE. Always
look for filter damage, even if a new filter element is
being installed. Pay special attention to the inside of
the open end (sealing area). Do not install a
damaged filter.
b.
INSERT THE FILTER PROPERLY. Refer to
(Figure 7-6). The seal area is on the inside of the
open end of the primary filter. A new filter has a dry
lubricant to aid installation. The critical sealing area
will stretch slightly, adjust itself and distribute the
sealing pressure evenly. To complete a tight seal,
apply pressure at the outer rim of the filter, not the
flexible center. No cover pressure is required to hold
the seal.
4.
Install the cover on the air cleaner body with the two
arrows pointing up. Secure the cover with the latches.
5.
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.
Vacuator Valve
Vacuator valves (Figure 7-7) are designed to expel loose
dust and dirt from the air cleaner body automatically, thus
lengthening the element service life. The valve lips must
point straight down and be kept free from 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 inside out, check for a clogged air cleaner inlet.
Malfunction of this valve does not reduce the air cleaner
effectiveness, but does allow the element to get dirty faster
and reduces serviceable life. If a valve is lost or damaged,
replace it with a new valve of the same part number.
Duct Work
1.
Check the intake pipe cap and screen for accumulation
of leaves, trash, and other debris that could restrict air
flow. Repair the screen or replace the cap if any large
holes are found in the screen.
2.
Check all mounting hardware for security to eliminate
possible vibration of intake piping. Such vibration leads
to early failure of hoses, clamps, and mounting parts,
