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
Air Cleaner - The air cleaner element should be inspected per the maintenance
intervals or more often if the engine is operated under severe dust conditions.
Replace the element, if necessary. Check the gaskets for deterioration and replace,
if necessary. If the dry type air cleaner is equipped with an aspirator, check for
aspirator damage or clogging. Clean, repair or replace, as necessary.
NOTICE: Do not allow the air inlet restriction to exceed 5.5 kPa (22 in.
H2O) under any engine operating conditions. A clogged air cleaner element
will cause excessive intake restriction and reduced air supply to the engine
resulting in increased fuel consumption, inefficient engine operation and
reduced engine life.
