57.5.5.1 Fresh Air Intake Filter
The fresh air filter is located under the cab roof
behind the rear window and should be serviced
daily. Service the filter as follows:
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Loosen knob (A) and slide retainer out to
release filter (B) from rear of cab roof.
b. Tap filter gently on a flat surface, dirty side
down. Do not tap on a tire, treads may damage
filter pleats.
c. Direct compressed air (100 psi [700 kPa]
maximum) through filter in opposite direction of
air flow arrows.
d. Wash filter as required:
1. Soak 15 minutes in warm water (not over
100 °F [40°C]) with Filter Element Cleaner,
(Donaldson D 1400 or equivalent).
2. Rinse thoroughly with clean water,
(maximum pressure 40 psi [275 kPa]).
3. Shake excessive water from filter and allow
element to dry. Do not use compressed air
to dry filter; it may rupture the wet element.
Protect element from freezing until dry.
e. Inspect filter before installing as follows:
1. Hold a bright light on one side element and
check carefully for holes. Discard any
element which shows the slightest hole.
2. Be sure outer screen is not dented. Vibration
would quickly wear a hole in the filter.
3. Be sure filter gasket is in good condition. If
gasket is damaged or missing, replace
element
f. If element is coated with oil or soot, replace the
element.
g. Reinstall filter, making sure air flow arrows point
towards cab.
