GENERAL
INFORMATION
DESCRIPTION
POWER
STEERING
PUMP
The power steering pump
is a
constant
flow
rate
and displacement, vane-type pump. The pump hous-
ing
and
internal components
are
combined
with
the
reservoir
to
form
a
one-piece mechanism.
The
inte-
gral
reservoir has
a
pressure
hose
attachment located
at the rear of the pump.
The power steering pump
is
connected to the
steer-
ing
gear
via
the
pressure
hose
and
the
return
hose.
Because
of the
unique shaft bearings,
flow
control
levels
and
pump displacements,
Ram
Truck
power steering pumps
are not
inter-
changeable
with
pumps installed
in
other
vehi-
cles,
