Service Instructions & Installation Tips
1
Release the
Seal Carefully
Unlatch and remove the service
cover of the air cleaner. Make
certain the latches are folded
back against the cover so
that they don't hinder filter
removal/installation. Most
latches are spring loaded to fold
back when open. The filter fits tightly
over the outlet tube, creating the critical
seal on the inside diameter of the filter
endcap. The filter should be removed
gently to reduce the amount of dust
dislodged. There will be some initial
resistance, similar to breaking the seal on
a jar. Gently move the end of the filter
back and forth to break the seal.
2
Avoid Dislodging
Dust from the Filter
Gently pull the filter
off the outlet tube
and out of the
housing. Avoid
knocking the filter
against the housing.
3
Clean Sealing Surface
of the Outlet Tube
Use a clean cloth to wipe the sealing
surface. Dust on the outside diameter of
the outlet tube could
hinder an effective
seal and cause
leakage. Make
sure that all
contaminant is
removed before
the new filter is inserted.
4
Clean the Inside of
the Outlet Tube
Carefully wipe the inside
of the outlet tube with
a clean cloth. Dirt
accidently
transferred to the
inside of the outlet
tube will reach the
engine and cause
wear. (Engine
manufacturer says that it takes only a
few grams of dirt to "dust" an engine!)
Be careful not to damage the sealing
area on the tube.

Check the Old
Filter for Leak Clues
Visually inspect the old filter for any signs
of leaks. A streak of dust on
the clean side of the filter
is a telltale sign.
Remove any cause
of leaks before
installing new
filter.
6
Inspect the New
Filter for Damage
Inspect the new filter carefully,
paying attention to the inside of
the open end,
which is the
sealing area.
NEVER install a
damaged filter.
7
Insert the New
TM
RadialSeal Filter
by Hand
Insert carefully. Seat the new filter by hand,
making certain it is completely into the air
cleaner housing place. If the cover hits the
filter before it is fully in place, remove the
cover and push (by hand) the filter further
into the air
cleaner and try
again. The
cover should
go on with no
extra force.
Never use the
latches on the
cover to force the filter into the air cleaner!
It is tempting to assume the cover will do
the job of seating the filter, but it will not!
Using the latches to push the filter in
could cause damage to the housing and
will void the warranty.

Donaldson filters with RadialSeal™ Sealing
Technology are self-aligning, self-centering,
and self-sealing. 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 by hand at the outer rim of the
filter, not the flexible center. (Avoid pushing
on the center of the urethane endcap.) No
cover pressure is required to hold the seal.
Again, do NOT use the service cover to
push the filter into place!
When the filter in is place, put the service
cover back on, making sure the Vacuator™
Valve points down. Inspect the Vacuator™
Valve for cracks or dust hang-ups to insure
that it is functioning properly. Re-fasten the
latches.

Check Connections
for Tight Fit
Make sure that all clamps, bolts, and
connections in the entire air intake system
are tight. Check for holes in piping, and
repair if needed.
