AIR CLEANER ELEMENT
REMOVAL
Testing Air Cleaner Element using Filter Minder™
Do not attempt to unnecessarily remove top of air
cleaner housing for air cleaner element inspection
on diesel engines.
The air cleaner (filter) housing (5) is equipped with an
air Filter Minder™ gauge (3). This air flow restriction
gauge will determine when air cleaner element is
restricted and should be replaced.
The Filter Minder™ (5) consists of a diaphragm and
calibrated spring sealed inside of a plastic housing. A
yellow colored disc (2) attached to diaphragm moves
along a graduated scale on side of Filter Minder. After
the engine has been shut off, a ratcheting device
located within Filter Minder will hold yellow disc at
highest restriction that air cleaner element has experi-
enced. A drop in air pressure due to an air cleaner
element restriction moves diaphragm and yellow disc
will indicate size of air drop.
CAUTION: Certain engine degreasers or cleaners
may discolor or damage plastic housing of Filter
Minder. Cover and tape Filter Minder if any engine
degreasers or cleaners are to be used.
To test, turn engine off. If yellow disc (2) has reached
red colored zone (3) on graduated scale, air cleaner
element should be replaced. Refer to Removal /
Installation.
Resetting Filter Minder:After air cleaner (filter) ele-
ment has been replaced, press rubber button on top of Filter Minder. This will allow yellow colored disc to reset.
After button has been pressed, yellow disc should spring back to UP position.
If Filter Minder gauge has reached red colored zone, and after an examination of air cleaner (filter) element, ele-
ment appears to be clean, high reading may be due to a temporary condition such as snow build-up at air intake.
Temporary high restrictions may also occur if air cleaner (filter) element has gotten wet such as during a heavy rain
or snow. If this occurs, allow element to dry out during normal engine operation. Reset rubber button on top of Filter
Minder and retest after element has dried.
