ENGINE AIR CLEANER MAINTENANCE
Tier 3 and Past Production
for the following procedure.
The air cleaner is mounted horizontally and fastened to the
engine air intake manifold with rubber elbows and metal
tubes. Servicing the engine air cleaner is an important
maintenance function:
•
A clogged air cleaner filter will prevent adequate air flow
to the engine, causing poor starting and increased
exhaust emissions.
•
An improperly installed or damaged air cleaner can
allow dirty air to be drawn directly into the engine.
Either condition can cause engine damage.
Inspection
To maintain engine protection and filter service life, inspect
the following areas at regular intervals:
1.
Check service indicator
daily
with engine running.
The indicator gives a visual signal when it is time to
replace the air cleaner.
The red flag in the indicator window rises as the air
cleaner fills with dirt.
Replace air cleaner when red flag
locks in place at top of indicator
.
The red flag remains up after the engine is stopped.
After the air cleaner is replaced, push the button
in
on
the indicator to reset it.
2.
Inspect elbows and tubes between air cleaner and
engine for cracks or other damage which might allow
unfiltered air to enter engine. Replace defective parts.
3.
Check air cleaner housing for dents or other damage
that may allow unfiltered air to enter engine. Replace air
cleaner if damaged.
4.
Check for loose clamps and tighten if required.
5.
Check that inlet cap is free of obstructions.
6.
Check that Evacuator™ Valve is open.
Service
for the following procedure
.
1.
Release seal carefully:
Unlatch and remove service cover. Make certain latches
are folded back against cover so that they don’t hinder
filter removal/installation. Most latches are spring loaded
to fold back when open. The air cleaner has two filters: a
primary and a safety. The filters should be removed
gently to reduce the amount of dust dislodged. There will
be some initial resistance, similar to breaking the seal on
a jar. Gently move the end of the primary filter back and
forth to break the seal.
2.
Avoid dislodging dust from filters:
Gently pull primary filter off outlet tube and out of
housing. Avoid knocking filter against housing.
Repeat steps 1 and 2 for safety filter.
3.
Clean sealing surfaces in housing:
Use a clean cloth to wipe sealing surfaces clean. Dust
on sealing surfaces could hinder an effective seal and
cause leakage. Make sure that all contaminant is
removed before new filters are installed.
4.
Clean inside of outlet tube:
Carefully wipe inside of outlet tube with a clean cloth.
Dirt accidentally transferred to inside of outlet tube will
reach engine and cause wear (engine manufacturers
say that it takes only a few grams of dirt to destroy an
engine). Be careful not to damage sealing area of tube.
5.
Check old filters for leak clues:
Visually inspect old filters for any signs of leaks. A streak
of dust on clean side of filter is a telltale sign. Remove
any cause of leaks before installing new filter.
6.
Inspect new filters for damage:
Inspect new filters, paying attention to inside of open
end, which is sealing area.
Never
install damaged filters.
7.
Install filters by hand:
Insert new safety filter carefully and seal it by hand,
making certain filter is completely seated in housing.
Repeat this step for primary filter.
8.
Install service cover:
Once filter is in place, put service cover back on, making
sure the Evacuator™ Valve points down. Re-fasten
latches. Cover should go on without extra force.
Never use latches on cover to force filters into air
cleaner. It is tempting to assume cover will do the job of
sealing the filter – but it will not. Using latches to push
filter in could cause damage to housing and will void
warranty.
Donaldson RadialSeal™ filters are self-aligning, self-
centering, and self-sealing. New filters have a dry
lubricant to aid installation. The critical sealing areas will
CAUTION
Engine Damage!
STOP ENGINE before servicing air cleaner, or unfiltered
air will be drawn directly into engine.
Do not attempt to clean and reuse old air cleaner. Discard
old air cleaner and install a new one.
