be configured individually or together depending
on vehicle application requirements. A front cover
mounted Power Take-off (PTO) devise can be used
in conjunction with the air compressor.

AIR COMPRESSOR

Air for braking is supplied by an air compressor
mounted on the lower left side of the engine. It is
gear driven from the lower idler gear located within
the front engine cover.
• Lubrication of the compressor is provided by
a hose connected at the engine oil pressure
sensor port with oil draining back to the crankcase
through an elbow at the bottom of the compressor.
• Filtered air is furnished through an air hose
connected to the air cleaner assembly, and
compressed into a supply tank. When the air
supply tank is full, compressed air is simply
vented to the atmosphere.
• Coolant to the compressor is supplied and
returned through two hoses to ports located
on the left side of the engine crankcase.

POWER STEERING PUMP

The power steering pump assembly is mounted in one
of two following configurations:
A. Without an air compressor, the power
steering pump is mounted onto rear half
of the front cover and is driven by the lower
idler gear that would normally drive the air
compressor.
B. With an air compressor, the power steering
pump is mounted to the air compressor.
The compressor is driven by the lower idler
gear and power is transferred through the
compressor crankshaft to drive the power
steering pump.
