Engine Air Cleaner System
Donaldson Radialseal™ Air Cleaner
A remote mounted Donaldson Radialseal™ air
cleaner provides the air ltering function. The paper
lter element slides over an outlet tube inside the air
cleaner canister with radial sealing action, eliminat-
ing the possibility of dust leaks due to improper lter
installation. Intake design, internal bafing, and a
dust ejection valve provide dust separation and au-
tomatic precleaning action. Daily or frequent servic-
ing of the air cleaner is not required. Use the air
lter restriction indicator on the air cleaner outlet to
indicate when the air lter needs servicing -- a yel-
low indicator will show when the lter is overly re-
stricting airow into the engine.
IMPORTANT: Use only Donaldson air lter ele-
ments for replacement (Donaldson P822686 or
Walker 5090-1). Aftermarket lters may not seal
properly or lter efciently.
