14000 SERVICE MANUAL POWER TRAIN
AIR CLEANER
See Figure 7-4
The air cleaner filters (7 and 8) require periodic
maintenance.
• Clogged air cleaner filters 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 filters at the specified intervals:
Daily
Check service indicator (10) with engine running. The
indicator gives a visual indication when it is time to replace
the filters.
A yellow flag in indicator window extends as the filters
become plugged. Replace filters when yellow indicator
reaches red zone at end of indicator.
The yellow flag remains locked in place after the engine is
stopped. The indicator reset button on the top of the indicator
can be pressed at any time. When the engine is running, the
indicator will return to the proper reading.
Monthly
• Inspect rubber reducer (5) and elbow (4) between air
cleaner and engine for cracks or other damage which
might allow unfiltered air to enter engine. Replace worn
or damaged parts.
• Check housing (2) for dents or other damage that may
allow unfiltered air to enter engine. Replace housing if
damaged.
• Check for loose clamps and bands (3). Tighten loose
parts.
• Inspect inlet cap (1) for obstructions. Clean as required.
Changing the Filters
The air cleaner has two primary filters (8) and one secondary
filter (7).
1. Remove service cover (9) carefully.
2. Remove the primary filters gently in order to reduce the
amount of dust dislodged. There will be some initial
resistance, similar to breaking the seal on a jar. Using
the tabs on the filters, move the end of filter back and
forth to break seal.
Avoid dislodging dust from filters.
NOTE The secondary filter should be replaced every third
time the primary filters are replaced. Inspect the
secondary filter and replace as necessary.
3. Remove secondary filter by pulling on the plastic ring
tabs.
4. Clean sealing surfaces in housing.
Use a clean cloth to wipe clean sealing surfaces and
inside of housing. Dust on the sealing surfaces could
render seal ineffective and cause leakage. Ensure all
contamination is removed before new filters are
installed.
5. 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. It takes only a few grams
of dirt to destroy an engine). Be careful not to damage
sealing area of tube.
6. Visually inspect old filters for leaks. A streak of dust on
clean side of filter is a telltale sign. Remove any cause of
leaks before installing new filter.
CAUTION
Potential Engine Damage
• Stop engine before servicing air cleaner. Otherwise,
unfiltered air will be drawn directly into engine. Never
operate engine without an air cleaner.
• Before servicing, clean the fittings, mounting
hardware, and the area around the component(s) to
be removed.
• Replace secondary filter as quickly as possible to
avoid engine ingestion of contaminants.
• Do not attempt to clean and reuse old filters. Discard
old filters and install new filters. Cleaning filter
elements by impact or compressed air voids the
warranty and can degrade or damage the filter media,
leading to engine damage.
