Engine Air Cleaner System; Donaldson Radialseal™ Air Cleaner - Walker B27i Operator's Manual

B27i
IMPORTANT: Yearly, it is good maintenance
practice to remove the engine cooling shroud and
clean the cylinder head cooling fins thoroughly to
prevent overheating and extend engine life. Make
sure cooling shroud is reinstalled properly. This
procedure will require removing the engine from
the chassis.

Engine Air Cleaner System

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 automatic precleaning action. Dai-
ly or frequent servicing of the air cleaner is not
required. Use the air filter restriction 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 P821575 or
Walker 5090-8 Primary/Donaldson P822858 or
Walker 5090-7 Safety Filter). Aftermarket filters
may not seal properly or filter efficiently.
