Finally,

(0.G{J2”),
which
will
set

b)
Remove

mount

c)
For
a
correct

(Fig.

pay
attention,
at
pinion
assembly,
to
the
number
stamped
upon
the
smaller
base
and
marl-ted
by
-+~
or
—~;
this
is
C§Ul’E8*
necessary
to
determine
that
thickness
ot
ring
Rh,
which
will
be
most
tit
to
avoid
noises
during
operation.
We
suggest
the
following
sequence:
»-
mount
the
bevel
pinion
shaft
titted
with
all
its
parts
and
with
a
ring
Rb
oi
any
thickness;
—
mount
on
the
casing
the
tool
A
133110,
according
to
Figs.
‘E12
and
113;
—-
rotate
the
tool
shalt
clockwise
so
that
the
eccentric
zone
contacts
the
pinion
base,
and
read
on
the
quadrant
graduated
from
92
to
94
mm
£3.62?’
to
3.700”)
the
value
at
which
rotation
stops.
it
this
value,
indicated
on
the
quadrant,
exceeds
the
one
calculated
by
adding
or
subtracting
from
the
theoretical
distance
existing
between
the
pinion
smaller
base
and
the
bevel
gear
axis
(93
mm
-
3.661”)
the
number
marlzed
on
the
pinion
(not
proceeded
by
any
letter
mark},
it
will
be
necessary
to
replace‘
ring
Rb.
The
ring
to
be
mounted
should
have
a
thickness
increased
of
an
amount
equal
to
the
difference
between
the
two
values.
On
the
contrary,
it
the
value
read
on

results
less
than
the
one
read
on
the
pinion
after
adding
or
subtracting
(accotding
to
the
+
or
M
sign)
from
93
mm
(3.6614”),
the
thickness
Rb
should
be
decreased.
