Air Filter Element: Service and Repair
TESTING AIR CLEANER ELEMENT USING FILTER MINDER
Do not attempt to unnecessarily remove the top of the 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. 11). This air flow restriction gauge will determine when the air
cleaner element is restricted and should be replaced.
The Filter Minder consists of a diaphragm and calibrated spring sealed inside of a plastic housing (Fig. 12). A yellow colored disc attached to the
diaphragm moves along a graduated scale on the side of the Filter Minder. After the engine has been shut off, a ratcheting device located within the
Filter Minder will hold the yellow disc at the highest restriction that the air cleaner element has experienced. A drop in air pressure due to an air
cleaner element restriction moves the diaphragm and the yellow disc will indicate the size of the air drop.
CAUTION: Certain engine degreasers or cleaners may discolor or damage the plastic housing of the Filter Minder. Cover and tape the Filter Minder
if any engine degreasers or cleaners are to be used.
