3.6 Drawings. Unless otherwise specified (see 6.2.1), the contractor shall
prepare drawings and technical manuals in accordance with the data ordering
document included in the contract or order (see 6.2.2) and the unique features
specified in 3.6.1 through 3.6.4 shall be included.
3.6.1 Drawing content.
3.6.1.1 General requirements.
3.6.1.1.1 "Manufacturer s use only*' notes. Information intended for manu-
facturer's use only shall beso designated. Conversely, on a commercial drawing
with wide usage it is permissible to designate portions thereon, "For Navy use
only.'*
3.6.1.1.2 Dimensional tolerance. Unless otherwise indicated by note,
legend, or key all tolerances shown on a drawing shall be complied with during
both manufacture and maintenance repair.
3.6.1.2 Design drawings. Design drawings shall consist of the drawings
described in 3.6.1.2,1 through 3.6.1.2.4.
3.6.1.2.1 Sectional assembly drawings. Sectional assembly drawings shall
include a sectional assembly with references to the list of material for identi-
fication of individual parts. All running clearances shall be shown and shall
be dimensioned and labeled as diametral clearances. (Diametral clearance equals
the difference between the diameters of mating parts.) This may necessitate some
side or partial view in order to show parts not otherwise shown in the main
section view. Tightening torques with tolerances and thread lubrication require-
ments for threaded fasteners shall be shown on the assembly drawing.
3.6.1 .2.2 List of material. The list of material shall include every
part required in the pump assembly, including those parts not required to be
detailed. The list of material shall include an indication of each part required
by this specification to be furnished as an on board repair part (this is not
a repair parts list). The list of material shall include the manufacturer's
drawing number and service part number for all parts for which detail drawings
are required (see 3.6.1.2.3) as well as quantity required, material type, and
material specification for all parts. Parts shall be named to indicate the
function they serve. Parts for which detail drawings are not required shall be
identified as to dimensions. The list of material may be shown on the sectional
assembly drawing.
3.6.1.2.3 Detail drawings. Detail drawings shall be furnished of all parts
and sub-assemblies necessary for evaluation of the equipment, and of all parts
necessary for maintenance and overhaul of the pumps. Details of these parts
shall be so complete as to permit emergency manufacture by a Naval shipyard with-
out assistance from the original manufacturer. Details of pump casing shall be
furnished. However, for all cast parts that carry substantial loads under shock,
the detail drawings shall specify minimum cross-sectional areas (whichever is
more appropriate). Sub-assemblies whose parts cannot be acquired or serviced
individually, shall be shown as a single part and so indicated. Multi-detail
drawings are preferred, but monodetail drawings may be used.
