Assembly Marking
An assembly marking system
is typically used on support
structures, chutes, conveyors,
and other parts of a structure.
Assembly Mark Numbers
When assembly is required,
drawings are included that
show the fi nished assembly
with associated assembly
mark numbers.
Assembly mark numbers
indicate three things. The fi rst
three digits represent the last
three digits of the machine’s
serial number. The next two
digits represent the last two
digits of the associated drawing
number.
The fi nal two digits represent
the individual piece number.
Example:
Last two digits of
drawing number
Individual piece
number
Last three
digits of serial
number
542-23-02
Other notations may appear
on the drawings indicating
individual piece location.
NS and FS are used to indicate
Near Side and Far Side. This
reference explains that a
piece indicated by Near Side
would be the piece located in a
position closest to the viewer.
The Far Side location would be
the piece located further from
the viewer.
On conveyors, one sheet
will include information such
as number of capscrews,
washers, and prevailing torque
locknuts used per conveyor
section, torque chart and
other pertinent assembly
information.
