DESCRIPTION
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
There are two, dual dry element type air cleaner
assemblies mounted on the platform to the right hand
side of the cab. Air cleaner assemblies prolong 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 cover
assembly (4) 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 vacuator valve (6) expelling
grit, dust and water as they collect. When the engine is
stopped, vacuator valve (6) opens and expels any
accumulated grit, dust or water.
An electrical air restriction gauge (14, Fig. 3) indicates
when air restriction levels reach the maximum
allowable limit. When air restriction levels are reached,

the circuit closes and a restriction indicator light in
the dash panel (Fig. 2) illuminates. This light shows
at a glance when the system air flow is being
restricted indicating that primary element (2) should
be serviced. Air restriction gauge (14, Fig. 3) automatically
resets after each air cleaner assembly is serviced.
While the indicator light indicates the need for
servicing, it does not give as precise a measurement
as a water manometer or vacuum gauge. Refer to
