B27i Maintenance Instructions
Cleaning
IMPORTANT: Yearly, it is good maintenance
practice to remove the engine cooling shroud and
clean the cylinder head cooling ns 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 ltering function. The
paper lter element slides over an outlet tube
inside the air cleaner canister with radial sealing
action, reducing the possibility of dust leaks due to
improper lter installation. Intake design, internal
ba󰀪ing, 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 lter restriction gauge on the
air cleaner outlet to indicate when the air lter
needs servicing – a yellow indicator will show
when the lter is overly restricting airow into the
engine.
IMPORTANT: Use only Donaldson air lter ele-
ments for replacement (Donaldson P821575 or
Walker 5090-8 Primary/Donaldson P822858 or
Walker 5090-7 Safety Filter). Aftermarket lters
may not seal properly or lter e󰀩ciently.
