(2) Install Adapter Fitting, Special Tool 6844, on
Pressure Hose, Special Tool 6713. Install Adapter Fit-
ting, Special Tool 6826, on Pressure Hose, Special
Tool 6959. Both Special Tool 6844 and 6826 can be
found in Adapter Set, Special Tool 6893 (Fig. 4).
(3) Unscrew the tube nut and disconnect the
power steering fluid pressure hose from the power
steering pump (Fig. 5).
(4) Connect Adapter Fitting, Special Tool 6844,
attached to pressure hose from inlet (gauge end) of
Power Steering Analyzer to the pressure fitting on
the power steering pump. Tighten the tube nut to a
torque of 34 N´m (25 ft. lbs.).
(5) Connect the vehicle's power steering fluid pres-
sure hose to Adapter Fitting, Special Tool 6826,
which should be already installed in the outlet hose
(valve end) of Power Steering Analyzer. Tighten the
tube nut to a torque of 34 N´m (25 ft. lbs.).
TEST PROCEDURE
(1) Completely open the valve on the Power Steer-
ing Analyzer flow meter.
(2) Start the engine and let idle long enough to cir-
culate power steering fluid through the analyzer and
hoses, until the air is out of the fluid. Shut the off
engine.
(3) Check the power steering fluid level and add
fluid as necessary. Start the engine again and let
idle.
(4) The analyzer gauge should read below 862 kPa
(125 psi). If above, inspect the hoses for restrictions
and repair as necessary. The initial pressure should
be in the range of 345-552 kPa (50-80 psi). The flow
meter should read between 1.1 and 1.3 GPM.CAUTION: The following test procedure step
involves testing maximum pump pressure output
and flow control valve operation. Do not leave valve
closed for more than five seconds as the pump
could be damaged.
NOTE: Power steering pump maximum relief pres-
sure is 9308 to 9998 kPa (1350 to 1450 psi.).
(5) Close the flow meter valve fully three times
and record highest pressure indicated each time.All
three readings must be above specifications
and within 345 kPa (50 psi) of each other.
²If the power steering pump pressure's are above
specifications, but not within 345 kPa (50 psi) of each
other, replace the power steering pump.
²If the pressure's are within 345 kPa (50 psi) of
each other, but below specifications, replace the
power steering pump.
If the power steering pump requires replacement,
refer to the section POWER STEERING PUMP
within this group for the removal and installation
procedure.

DIAGNOSIS AND TESTING (Continued)

CAUTION: Do not force the pump to operate
against the stops for more than 5 seconds at a time
as pump damage may result.
(6) Completely open the valve on the Power Steer-
ing Analyzer flow meter. Turn the steering wheel to
the extreme left until the stop in the steering gear is
met, then turn the steering wheel to the right until
the right stop is met. Record the highest indicated
pressure at each position. Compare the recorded
readings to the specifications. If the highest output
pressure reading against one stop is within 50 psi of
the highest reading at the other stop, the steering
gear is leaking internally and must be replaced.
If the power steering gear requires replacement,
refer to the section POWER STEERING GEAR
within this group for the removal and installation
procedure.
SERVICE PROCEDURES
POWER STEERING SYSTEM FLUID LEVEL
CHECK
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT PERSONAL
INJURY FROM MOVING PARTS.
Before opening power steering system, wipe the
reservoir filler cap free of dirt and debris. Remove
the cap and check the fluid level on its dipstick.
When the fluid is at normal ambient temperature,
approximately 21ÉC to 27ÉC (70ÉF to 80ÉF), the dip-
stick level should indicateCOLD. Do not overfill the
power steering system. In all power steering systems,
use only Mopar Power Steering Fluid, or its equiva-
lent.
NOTE: Do not use any type of automatic transmis-
sion fluid in the power steering system.

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.
