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 is equipped with an
air Filter Minder™ gauge (Fig. 6). This air flow
restriction gauge will determine when air cleaner ele-
ment is restricted and should be replaced.
The Filter Minder™ consists of a diaphragm and
calibrated spring sealed inside of a plastic housing
(Fig. 7). A yellow colored disc attached to diaphragm
moves along a graduated scale on side of Filter
Minder. After the engine has been shut off, a ratch-
eting device located within Filter Minder will hold
yellow disc at highest restriction that air cleaner ele-
ment has experienced. 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 (Fig. 7) has
reached red colored zone on graduated scale, air
cleaner element should be replaced. Refer to Removal
/ Installation.
Resetting Filter Minder: After air cleaner (filter)
element has been replaced, press rubber button on
top of Filter Minder (Fig. 7). 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, element 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 got-
ten 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.
