CHRYSLER SERVICE MANUAL
STEERING—255
adjust steering column jacket to provide proper
clearance. Install horn ring and horn wire in
steering wheel and install horn ring ornament.
Install dust pads and retaining plate.
Tighten front upper and lower gear housing
to frame attaching bolts 20 foot-pounds torque.
Install wedge over rear bolt between housing
and frame, tapping it lightly in place. Tighten
three attaching bolts 70 foot-pounds torque.
Connect hoses from steering gear to hydraulic
pump.

ADJUSTMENT OF POWER STEERING
GEAR (INSTALLED)
Adjusting Manual Control Valve (Centering Hy-
draulically) in Car.
Where it is difficult to rotate steering wheel
in one direction but not in other direction, or
where wheels turn of their own accord, equalize
tire pressure and check front wheel alignment.
If above conditions still exist, it is an indica-
tion that control valve is out of alignment.
Remove parts, as necessary, to gain access
to steering tube coupling. Remove coupling re-
taining screw, lockwasher, and plain washer
from worm shaft. Insert manual control valve
centering tool (slotted end first) into worm
shaft and engage tool with tang on control
valve operating rod. Two men are required to
center valve.
One man moves valves, as directed, while the
other checks torque required to move steering
gear arm through its travel in both directions.
Move steering gear arm through travel from
one extreme to the other with torque wrench
(Tool C-3005 and 1
7
/
16
inch socket), and ob-
serve torque reading. The torque should be same
in both directions. Turn adjusting rod, as re-
quired, until an equal torque reading is ob-
tained. The steering gear arm retaining nut
should be tightened to 120 foot-pounds torque.
NOTE
Where gear shaft requires more than 40 foot-
pounds torque to rotate it, and/or where torque
is uneven at any point through full travel of
shaft, it probably has a cocked gear shaft cover,
dirt has entered interior, or circulating balls
are defective or improperly installed.

REPLACING STEERING GEAR SHAFT
OIL SEAL
The steering gear shaft oil seal may be re-
placed (with the unit in car) similar to the
method outlined in Paragraph 15, e.
20.
HYDRAULIC STEERING PUMP
PRESSURE CHECK
Should lack of steering assistance (in both di-
rections) be encountered and other checks fail
to reveal cause, a pressure check should be made
to determine if pump is operating properly, as
follows:
Connect tachometer leads to coil and ground.
Install gauge C-3309 in pressure line between
pump and hose. Refill reservoir to proper level.
Open valve on gauge, start engine, and run un-
til power steering oil pump reaches operating
temperature. With engine idling (475-500 r.p.
m.), turn shut-off valve on gauge to closed posi-
tion.
CAUTION
Do not keep valve closed more than a few sec-
onds or accelerate engine with valve closed:
otherwise, damage to the pump and/or belt
may result.
If pressure does not gradually increase to at
least 700 psi. as valve is closed, it is possibly
due to following conditions:
Fan belt slipping. To correct, adjust the
belts.
Where two belts are used, make sure
