Chrysler Stratus Convertible. Manual - part 39

ASSEMBLE

(1) Install power steering pump on mounting

bracket. Install the power steering pump to mounting
bracket attaching bolts. Torque the mounting bolts to
54 N·m (40 ft. lbs).

CAUTION: Do not hammer on power steering pump
pulley or shaft to remove power steering pump pul-
ley. This will damage the pulley and the power
steering pump.

(2) Place power steering pump pulley squarely on

end of power steering pump shaft (Fig. 25).

(3) Place Installation Spacer, Special Tool 6936 on

top of the power steering pump pulley (Fig. 26).

(4) Mount Installer, Special Tool C-4063 in internal

threads of the power steering pump shaft and
against Special Tool 6936 on power steering pump
pulley (Fig. 27).

(5) Ensuring that special tool and pulley remain

aligned with pump shaft, force pulley onto power
steering pump shaft until Special Tool 6936 is
against the end of the shaft. When Special Tool
6936 is against the shaft of the power steering
pump, Special Tool C-4063 will no longer be
able to be turned.

(6) Remove Installer, Special Tool C-4063 from

power steering pump.

(7) Install

and

bracket

assembly back on engine. Refer to Power Steering
Pump Installation in the Power Steering Pump Ser-
vice Procedures section in this group of the service
manual for required procedure.

DESCRIPTION AND OPERATION

POWER STEERING GEAR

DESCRIPTION

The steering gear on this vehicle is a rack and pin-

ion unit with power assist (Fig. 1). It is mounted on
the front suspension crossmember. The steering col-
umn connects to the steering gear shaft on top of the
gear. The outer tie rod ends of the gear connect to
each suspension steering knuckle to steer the vehicle.

Depending on the vehicle production date, the

vehicle could use one of two power steering gears.
There is an early production steering gear and a
later production gear. Externally, the power steering
gears appear the same. Without a parts book, the
easiest way to identify whether your car is equipped
with an early or later production steering gear is to
identify what type of steering column intermediate
shaft the vehicle has. Early models use a intermedi-
ate shaft with a slap coupler connection at the steer-
ing gear pinion shaft (Fig. 2). Later models use a
slider-stage style intermediate shaft (Fig. 3).

An easy way to identify an isolated steering gear is

to look at the very end of the pinion shaft. Early

models have 2 parallel flats on the end where the
steering column intermediate shaft would bolt up
(Fig. 4). Later models have 2 flats that are at 60
degree angles to one another where the steering col-
umn intermediate shaft would bolt up (Fig. 4).

OPERATION

Turning of the steering wheel is converted into lin-

ear travel through the meshing of the helical pinion
teeth with the rack teeth. Power assist steering is
provided by an open center, rotary type control valve
which directs fluid from the pump 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 fluid behind the integral rack piston, which,
in turn, builds up hydraulic pressure and assists in
the turning effort.

The drive tangs on the gear pinion 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. However, under
these conditions, steering effort will be increased.
