DESCRIPTION AND OPERATION
POWER STEERING PUMP
The hydraulic pressure for operation of the power
steering gear is provided by a belt driven power
steering pump (Fig. 1) manufactured by TTA. The
TTA power steering pump is a constant flow rate and
displacement vane-type pump.
In the event of a power steering pump drive belt
failure, manual steering control of the vehicle can
still be maintained. However, under these conditions,
steering effort will be significantly increased.No repair procedures are to be done on the internal
components of the power steering pump. The only
serviceable components of the power steering pump
are the power steering pump pulley and the pump
itself. The power steering fluid reservoir is serviced
with the pump.
Because of unique shaft bearings, flow control lev-
els or pump displacements, power steering pumps
may be used only on specific vehicle applications. Be
sure that all power steering pumps are only replaced
with a pump that is the correct replacement for that
specific application.
Hydraulic pressure is provided for operation of the
power steering gear by the belt driven power steering
pump (Fig. 1). It is a constant displacement, vane
type pump. The power steering pump is connected to
the steering gear by a power steering fluid pressure
hose and return hose.
Rectangular pumping vanes in the shaft driven
rotor move power steering fluid from the intake to
the cam ring pressure cavities of the power steering
pump. As the rotor begins to turn, centrifugal force
throws the vanes against the inside surface of the
cam ring to pickup residual oil. This oil is then forced
into the high pressure area. As more oil is picked up
by the vanes, the additional oil is forced into the cav-
ities of the thrust plate through two crossover holes
in the cam ring and pressure plate. The crossover
holes empty into the high pressure area between the
pressure plate and the housing end cover.
As the high pressure area is filled, oil flows under
the vanes in the rotor slots, forcing the vanes to fol-
low the inside surface of the cam ring. As the vanes
reach the restricted area of the cam ring, oil is forced
out from between the vanes. When excess oil flow is
generated during high-speed operation, a regulated
amount of oil returns to the pump intake side
through a flow control valve. The flow control valve

reduces the power required to drive the pump and
holds down temperature build-up.
When steering conditions exceed maximum pres-
sure requirements, such as when the wheels are
turned against the stops, the pressure built up in the
steering gear exerts pressure on the spring end of the
flow control valve. The high pressure lifts the relief
valve ball from its seat and allows oil to flow through
a trigger orifice located in the outlet fitting. This
reduces pressure on the spring end of the flow con-
trol valve which then opens and allows the oil to
return to the intake side of the pump. This action
limits maximum pressure output of the pump to a
safe level.
Under normal power steering pump operating con-
ditions, pressure requirements of the pump are below
maximum, causing the pressure relief valve to
remain closed.
POWER STEERING FLUID RESERVOIR
The power steering fluid reservoir is mounted on
the power steering pump using 3 bolts (Fig. 1). It
stores fluid for the power steering system.
The power steering fluid reservoir is considered an
integral part of the power steering pump and is not
serviced separately.
SERVICE PROCEDURES
POWER STEERING PUMP INITIAL OPERATION
CAUTION: The fluid level should be checked with
engine off to prevent injury from moving compo-
nents. Use only MoparTPower Steering Fluid. Do
not use automatic transmission fluid. Do not over-
fill.
Wipe the filler cap clean, then check the fluid level.
The dipstick should indicateCOLDwhen the fluid is
at normal temperature, approximately 21ÉC to 27ÉC
(70ÉF to 80ÉF).
(1) Fill the power steering fluid reservoir to the
proper level and let the fluid settle for at least two
minutes.
(2) Start the engine and let run for a few seconds,
then turn the engine off.
(3) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
(4) Raise the front wheels off the ground.
(5) Start the engine. Slowly turn the steering
wheel right and left, lightly contacting the wheel
stops.
(6) Add power steering fluid if necessary.
(7) Lower the vehicle and turn the steering wheel
slowly from lock to lock.(8) Stop the engine. Check the fluid level and refill
as required.
(9) If the fluid is extremely foamy, allow the vehi-
cle to stand a few minutes and repeat the above pro-
cedure.

DESCRIPTION AND OPERATION
POWER STEERING GEAR
The power steering gear is mounted on the front
suspension crossmember (Fig. 1). The outer ends of
the outer tie rods attach to the steering knuckles.
The power steering gear operates as follows: Turn-
ing of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth of the gear. Power assist
steering is provided by a pump supplying fluid to
either side of the integral rack piston.Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. This movement
directs oil behind the integral rack piston, which, in
turn, builds up hydraulic pressure and assists in the
turning effort.
The drive tangs on the pinion of the power steering
gear mate loosely with a stub shaft. This is to permit
manual steering control to be maintained if the drive
belt on the power steering pump should break. How-
ever, under these conditions, steering effort will be
increased.
