CHRYSLER SERVICE MANUAL
either end) of the rack over center line of the
gear shaft cover opening in gear housing. Posi-
tion the middle tooth of the gear shaft with the
third tooth groove from (either) end of rack.
Insert gear shaft assembly with cover attached
into gear housing, and tap lightly into position,
as shown in Figure 50. It is of the utmost im-
portance that the center tooth of the gear shaft
lines up with the center slot in the lower piston
rod rack. Failure to observe this precaution will
result in a broken gear housing. Install gasket
and cover and tighten the cover screws evenly.
e. Seal
Before attempting to install a new gear shaft
seal, thoroughly clean the sealing surfaces on
the gear shaft and counterbore of steering gear
shaft oil seal with Lubriplate and place (lip of
seal down) on a piece of clean paper. Carefully
install tapered end of sleeve (part of Tool
C-3350) in seal and slide seal back approxi-
mately 14 *

on sleeve. Install this assembly
(lip of seal toward housing) over steering gear
shaft until seal contacts counterbore in housing.
Push seal into position by installing adaptor over
sleeve, and installing coupling nut on shaft
threads until shoulder of adaptor contacts hous-
ing, as shown in Figure 51. Remove nut and
adaptor. Wrap a new piece of friction tape
around sleeve to provide a firm grip and, with a
turning motion, remove sleeve from seal and
gear shaft, as shown in Figure 52. Seal is then
positioned properly. Install oil seal lock ring
(circular section) and make sure it is properly
seated. Install gear shaft adjusting screw lock
nut, but do not tighten.
f. Assembly of Worm Connector
(If Disassembled)
Insert worm into connector and visually align
the upper portion of the passages with the ball
guide holes. The balls which are used in the
worm connector are a select fit with each other.
If any of them become lost or damaged, a com-
plete set (40) must be installed. Balls which fit
tight will result in increased and erratic steer-
ing effort and also lack of returnability. Balls
which fit too loose will result in free play of the
steering wheel before valve actuation or steer-
ing is accomplished.
Insert 30 worm balls (no more) into lower
hole by tapping them in gently (use the rubber
end of lead pencil or similar object) while
slightly oscillating the worm. When the 30 balls
have been inserted, they should be visible in the
other hole. Place the remaining worm balls (10)
in either half of the worm connector ball guide.
Grease end balls to help hold them in place and
add other half of ball guide assembly. Insert
assembly into holes until it seats on worm con-
nector. Place ball guide clamp into position on
ball guide, install the two lockwashers and
screws and tighten to 12 foot-pounds torque.
Check the operation of worm, making sure it is
free to turn the maximum travel of the worm
shaft. Caution should be exercised not to bottom
worm in the outward direction. Otherwise, dam-
age to the ball return guide may result and
cause a rough or tight operating worm.
Slide the worm connector and worm shaft
assembly over control spacer and screw worm
connector nut onto connector. Pull worm shaft
up about one inch and wrap several layers of
masking tape around worm. Hold worm con-
nector with Tool C-3321. Using Tool C-3326,
tighten the nut. Stake ring with punch and re-
move masking tape.
g. Assembly of Worm Housing
If bearing cups were removed from worm hous-
ing during disassembly, refer to Figure 20 and
proceed as follows. Install worm housing upper
bearing cup (wide section of cup first) into
worm housing. Make sure cup seats properly in
housing. Install worm housing lower bearing
cup (wide section of cup first) into worm hous-
ing. Make sure cup seats properly in housing.
h. Installation of Worm Housing
Lubricate worm housing inner bearing race
with Lubriplate, and slide (wide section of cone
first) over threaded end of worm until it seats.
Lubricate worm connector guide rail with Lu-
briplate. Lubriplate upper housing head "O"
ring with Lubriplate and install on housing
head pilot opposite piston side. Install "O" ring
on inner land of housing head. If it is installed
