IDENTIFYING
PARTS
Where
the
construction
permits,
each
part
is
stamped
with
its
part
number.
Parts
too
small
for
a
complete
catalog
stamping
are
identified
by
letter
symbols
which
distinguish
one
part
from
another
that
is
similar
in
appearance.
Part
numbers
represent
the
same
part,
regardless
of
catalog
in
which
they
appear.
IMPORTANT!
ON
ALL
ORDERS,
PLEASE
INCLUDE
PART
NAME
AND
STYLE
OF
MACHINE
FOR
WHICH
PART
IS
ORDERED.

The

of
this
catalog
is
to
facilitate
easy
and
accurate
ordering
of
Class
63900
replacement

Seven
exploded
view
plates
cover
the
Standard
Styles
listed
in
this
catalog.
Each
plate
presents
a
sector
of
the
machine,
parts
being
aligned
as
in
their
assembled
position.
Small
keyline
views
show by
a
blackened
area
exactly
where
the
parts
being
discussed
fit
in
the
assembled
machine.
On
the
page
opposite
the
illustration
will
be
found
a
listing
of
the
parts
with
their
part
numbers,
descriptions
and
the
number
of
pieces
required
in
the
particular
view
being
shown.
Numbers
in
the
first
column
are
reference
numbers
only,
and
merely
indicate
the
position
of
the
part
in
the
illustration.
Reference
numbers
should
never
be
used
in
ordering
parts.
Always
use
the
part
number
listed
in
the
second
column.
Each
exploded
view
plate
carries
a
reference
number
for
each
part
available
for
sale.
Sub-
assemblies,
which
are
sold
complete,
or
by

are
in
a

or
a
solid

on
the
picture
plate.
