AIR INTAKE ACCESSORIES



Advantages of ScavengingScavenging is accomplished by introducingasecondaryairflowtothe drop tube on the air cleaner (generally through the use of an ejectororejectormuffler).This flowpullstheseparatedcontaminant from the pre-cleaner and inserts it into the exhaust stream.

•Higherpre-cleanerefficiency(resulting in longer filter service life)

•Completelyself-servicing(noregularmaintenance needed on pre-cleaner)

Aspirating an intake system through the use of a scavenging device adds more components (an ejector and some plumbing) to the overallsystem,butwillenhancethe separator efficiency of the pre- cleanerandconsequentlyextendthe filter service life.

Service ProcedureThe pre-cleaner/rain cap may need to be cleaned over time. The procedure requires removal and disassembly of the unit to clean. The unit can be cleaned with either water, mild-soapy water or compressed air. Tapping or hitting the components to dislodge contaminant should be avoided. It may cause damage and prevent reassembly.





1. Turn off engine.

2. Loosenbothconnectingclamps (metal pipe and scavenge hose) and remove the Strata Cap pre-cleaner.

Note: Cover or plug intake pipe to protect air intake system from contamination during service.

3. Turnunitupsidedown.Removethescrews(saveforreassembly) and disassemble theunit(screenistwopieces).

4. Cleanallthepartstoremovedust and debris from each component.

5. After cleaning, inspect the gasket on the perimeter of theupperbaffle.Ifdamagedinanywayreplacewithnewgasket. Check gasket position, make sure it is installed evenly aroundupperbafflepermitter.

Note: Using the unit without gasket properly installed will affect Strata Cap pre-cleaning performance.
