Inspection
and

Adjustment

Thoroughly
clean
all

parts
and
examine
them
for

signs

of
wear
or

damage
Replace
any
comIK
nent
found
to
be
un

satisfactory

It
is
advisable
to
renew
the
assemblies
if
the

steering
column

or
ball
nut

assembly
is
defective
as

the

adjustment
procedures

required
to
overhaul
the
units
are
rather
involved

The

dismantling
and

adjustment
procedures
for
the
ball

nut

assembly
can
be
carried
out
in

the
following
manner
if
it

is

decided
that
overhaul
procedures
are
to

be
carried
out

Ball

Remove
the
ball

guide

withdraw
the

guide

tubes
from
the
ball

and
collect
the
steel
balls

Turn
the
nut

upside
down
and
rotate

the
steering
column

backwards
and
forwards
until
all

36
steel
balls
have

dropped

out
of
the
ball
nut
Pull
the
ball

nut
from
the

Inspect
the

that

they
are

not

Pay
particular
attention

to
the
ends
of
the

that

pick
up
the

balls
from
the

path
Renew
the
tubes
if

they
are

unsatisfactory
Check
the
steel
balls
and

the
ball
nut

for
wear
and

replace
the

complete
unit
if

necessary

Assemble
the
ball

upwards
Drop
18
balls
into
each
of

the
two
holes
on
the

same
side
of
the
ball
nut

until
all
36
balls
are
installed
The

column
should
be

gradually
turned

away
from
the
hole

being

filled
and
if
the
balls
are

stopped
by
the
end
of
the
column
hold

down
those

already
installed
with
a

clean
rod
or

punch
while

turning
the
column
several
times
in
the
reverse
direction
The

filling
of
the
circuit
can
then
be
continued
but
it

may
be

necessary
to
turn
the
column
backwards
and
forwards

holding

the
balls
down
first
in
one

hole
and
then
the
