The rotate

is
secured to
the

wedging block and a set
screw.
The

is
accessible
from
below with
the

centered
over

the

After loos-
ening

the
grip
of
the

must be broken by rotating
the

This
can be done by inserting

and
the

con-
trolled
by a shim
located
between

The height
relative

controlled
in order
to

If

Tilt
Ring
- The upper ball socket should be
centered
over
the
lower ball
socket
within
.002".
It
is
adjusted by
moving
thetilt
ring left or right
after
loosening
the
tilt
ring pivot
set
screws. All side
play
of
the
tilt
ring
should be removed by
the
pivot pins while still allowing
the
ti
It
ring
tv
pivot
freely.
If
the ti
It
ring
is
not properly
centered,
the
rotate
posi-
tion of
the
head
can
vary
slightly
as
the
head
is
tilted
to the different
tilt
positions.
This
could
constitute a
portion
of
the
band width in
the
rotate
system.
The
ti
It
ring
is
centered
at
the
factory and
every
effort
should be made
to
maintain its
centered
position.
If
tilt
ring removal or
replacement
is
necessary,
a
feeler
gauge
should be inserted between
the
tilt
ring and
the
yoke to
determine
the
clearance
before
the
tilt
ring
is
removed.
The
tilt
ring should
be
replaced
to
the
same
clearance.
The
tilt
ring
can
easily
be
removed
if
the
machine
is·half
cycled
to
a two
tilt
position.
On
machines prior to
the
gearless
tilt
mechanism,
care
should be
taken
to insure
that
the
ti
It
sector
gears
are
properly meshed whenever
the
tilt
ring
is
installed.

rear
tooth
of
the
tube

gear
shou
Id
enter
the

of
the ti
It

gear
(Fig.

CAUTION: Side

in

Upper Ball Socket - The upper ball socket must
rotate
completely free of binds with
little
or no up and down
play.
The
adjustment
is
made by raising or lowering
the
tilt
ring
spacer
by installing
thicker
or thinner
shi~s
at
the
front and rear
(Fig.
49).
In
order
to
check
the
upper ball socket for binds
it
is
necessary
to
remove
the
ball joint so
that
the
upper
ball
socket
can
be
rotated
by
hand.
This
can
be done
either
by removing
the
tilt
ring and upper ball socket
together
and checking them off
the
machine
or
by removing
the
upper ball socket
and
replacing
it
without
the
ball
joint.
If
the
tilt
ring is removed, its position
relative
to
the
yoke must be
checked
by a thickness
gauge
before
re-
moval.
NOTE:
If
the
upper ball
socket,
tilt
ring,
or
tilt
ring
spacer
are
ever
replaced
by new
parts,
the
shimming
adjustment must be
checked.
