DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1.
The dual dry element air cleaner is remote mounted
horizontally on the right hand fender of the machine.
The air cleaner prolongs engine life by removing grit,
dust and water from the air as it enters the engine. Grit
and dust, combined with engine oil, forms a highly
abrasive compound which can destroy the engine in a
comparatively short period of time.
A rubber vacuator valve (6) attached to end cover (1)
in a downward position, ejects grit, dust and water
while the engine is running. Vacuator valve (6)
minimizes the need for daily servicing. Even though
vacuator valve (6) is normally under a slight vacuum
when the engine is running, pulsing of the vacuum
opens and closes the rubber valve, expelling dust and
water as they collect. When the engine is stopped,
vacuator valve (6) opens and expels any accumulated
grit, dust or water.

A mechanical air restriction gauge (16, Fig. 2) is
mounted on the air cleaner body and shows when the
system air flow is being restricted. A red band
gradually rises in the gauge window as air restriction
increases. The red band is locked when maximum
allowable restriction is reached. When the red band
locks at the top of the gauge window, primary filter
element (2) should be serviced. Air restriction gauge
(16, Fig. 2) should be reset by pushing the button on
the gauge, holding it for several seconds and then
releasing it.
While air restriction gauge (16, Fig. 2) indicates the
need for servicing, it does not give as precise a
measurement as a water manometer or vacuum
gauge. Refer to 'Measuring Air Restriction'.
Secondary (safety) element (3) is installed in air
cleaner body (1) inside of primary element (2). This
element increases the reliability of the air cleaner's
