with Friction Tape
upper portion of passages with ball guide holes.
The balls, which are used in worm connector,
are a select fit with each other. If any become
lost or damaged, a complete new set (40 balls)
must be installed. Balls which fit tightly will re-
sult in increased and erractic steering effort and
also lack of returnability. Balls which fit too
loosely will result in free play of steering wheel
before valve actuation or steering is accom-
plished.
Insert 30 worm balls (one at a time) into
lower hole by tapping them in gently (use the
rubber end of a lead pencil or similar object)
while slightly oscillating the worm. When 30
balls have been inserted, the first one installed
should be visible in the upper hole. Place re-
maining worm balls (10) in either half of
worm connector ball guide. Grease end balls
to help hold them in place and add the other
half of ball guide assembly. Insert assembly
into holes until it seats on worm connector.
Place ball guide clamp into position on ball
guide, install two lockwashers and screws, and
tighten 12 foot-pounds torque. Check opera-
tion of worm, making sure it is free to turn
maximum travel of worm shaft. Care should
be exercised not to bottom worm in outward
direction; otherwise, damage to ball return
guide may result and cause a rough or tight
operating worm.
Slide worm connector and worm shaft as-
sembly 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 to prevent nut from
bottoming. Hold worm connector with Tool C-
3321.
Using Tool C-3326, tighten nut. Stake
ring with punch and remove masking tape.
g. Assembly of Worm Housing
If bearing cups were removed from worm
housing during disassembly, refer to Figure 7,
and proceed as follows: Install worm housing
upper bearing cup (wide section of cup first)
into worm housing. Make sure cup seats prop-
erly in housing. Install worm housing lower
bearing cup (wide section of cup first) into
worm housing. 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 upper housing head "0" ring and
install on housing head pilot opposite piston
side. Install "O" ring on inner land of housing
head. If it is installed on outer land, damage to
housing will result when installed.
Drop inner bearing into housing and hold
in place. Guide worm housing over rails on
worm connector (ball guide down) until it is
flush with gear housing. If flanges cannot be
installed flush, the housing head "O" ring is
installed on outer land rather than on inner
land and will have to be changed. Worm hous-
ing cannot be installed if bearing is installed
on worm shaft prior to installing housing.
