TOPIC 2. AIR CLEANER(SRT)

A. DESCRIPTION

The air cleaner is mounted on the side of the engine and

is connected to the carburetor air intake by tubing and

hose. It prevents dust, chaff, or other foreign matter, the

chief causes of engine wear, from entering the manifold

and engine.

The air enters the cleaner and passes through a

replaceable type, dry filter element. The element is

constructed of pleated paper and bound at the edges

with plastic. This construction filters and removes the

fine dust particles from the air stream intake. This clean

and purified air is then drawn through the center tube of

the element and into the carburetor and intake manifold.

For continued efficient engine operation, the iii cleaner

must be properly serviced.
