B23 Maintenance Instructions
Cleaning
IMPORTANT: Yearly, it is good maintenance prac-
tice to remove the engine cooling shroud and clean
the cylinder head cooling ns and cooling fan
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.
