Three-Filter Fuel Filters
The prefilter is housed within the fuel filter module. The prefilter element filters
particles down to 100 microns and is snapped into the prefilter cap. The water
separator/coalescer filter is housed within the fuel filter module. The water
separator/coalescer has the task of separating out the water contained in the fuel
and also filtering out particles down to 10 microns. The water separator/coalescer
filter snaps into the water separator/coalescer cap. The final filter is housed within
the fuel filter module. The final filter element filters particles down 3 to 5 microns
and snaps into the final filter cap.
Two-Filter Fuel Filters
The prefilter is housed within the fuel filter module. The prefilter element filters
particles down to 100 microns and is snapped into the prefilter cap. The coalescer/
final filter is housed within the fuel filter module. The coalescer/final filter has the
task of separating out the water contained in the fuel and also filtering out particles
down to 3 to 5 microns. The coalescer/final filter snaps into the coalescer/final filter
cap.
Air System
The air cleaner restriction indicator (filter minder) should be inspected per the
maintenance intervals or more often if the engine is operated under severe dusty
conditions. Replace the element if the filter minder has reached maximum
allowable restriction. Refer to OEM literature for further details on filter minders.
NOTICE: Do not allow the air inlet restriction to exceed maximum allowable
restriction.
Table 19.
Air Cleaner Restriction
EPA07 DD Platform 5.5 kPa (22 in. H2O)
EPA10 DD Platform 5.5 kPa (22 in. H2O)
GHG14 DD Platform 4.5 kPa (18 in. H2O)
GHG17 DD Platform 4.5 kPa (18 in. H2O)
A clogged air cleaner element will cause excessive air intake restriction and
reduced air supply to the engine resulting in increased fuel consumption, inefficient
engine operation, aftertreatment failure and reduced engine life. High intake
restriction will also cause oil pullover from the turbocharger into the charge air
system.
