Donaldson Radialseal™ Air Cleaner
A remote mounted Donaldson Radialseal™ air
cleaner provides the air filtering function. The paper
filter element slides over an outlet tube inside the air
cleaner canister with
radial
sealing action, reducing
the possibility of dust leaks due to improper filter
installation. Intake design, internal baffling, and a
dust ejection valve provide dust separation and
auto matic precleaning action. Daily or frequent ser-
vicing of the air cleaner
is not required.
Use the air
filter re striction gauge on the air cleaner outlet to
indicate when the air filter needs servicing -- a yellow
indicator will show when the filter is overly restricting
airflow into the engine.
IMPORTANT:
Use
only
Donaldson air filter ele-
ments for replacement (Donaldson P822686 or
Walker 5090-1). Aftermarket filters may not seal
properly or filter efficiently.

Inspect the paper element
after
every 100 hours
of
service and
replace
the element and safety filter
yearly
(or when dirty or damaged). More frequent
replacement may be required when operating in ex-
tremely dusty con ditions as indicated by the air filter
restriction gauge. Ser vice the air cleaner as fol-
lows:
1. Release the top and bottom cover latches and
remove the air cleaner cover. Wash the cover
and dust ejection valve. Check that these com-
ponents are in good condition. The dust ejec-
tion valve is subject to wear and deterioration
and should be inspected carefully and replaced
yearly
or when damaged. The lips of the valve
should close and fit togeth er; any cracks, defor-
mation, or wear in the valve is cause for re-
placement.
2. Remove the filter element by pulling it out of the
canister. There will be some initial resistance
as the filter seal breaks loose and slides off of
the outlet tube.
Gently
move the end of the
filter up and down and side to side or twist to
loosen the seal. Use gentle action to minimize
the amount of dust dislodged as the filter is re-
moved.
3. Discard the filter element if excessive air flow
restriction has been indicated by the air filter
restriction gauge and proceed to Step 6. Clean
the filter element by
gently tapping
on a
flat,
hard surface.
If excessive restriction still exists
after cleaning the element, it should be re-
placed
.
