Castings and forgings. All parts, components, and
3.11.1
assemblies of the loader which include castings and forgings shall be
clean of harmful extraneous material such as sand, dirt, sprues, burrs,
scale, and flux. Rework shall be limited to procedures that do not
reduce mechanical properties or affect function. Castings with fastener
holes shall provide for correct seating of fasteners such as bolt,
lockwasher and nut assemblies and capscrews.
Metal fabrication. Metal used in fabrication shall
3.11.2
be free from kinks and sharp bends. The straightening of material shall
be done by methods that will not cause injury to the material. Corners
shall `be square and true. Flame cutting using tips suitable for the
thickness of the steel may be employed instead of shearing or sawing.
All bends shall be made with controlled means to insure uniformity of
size and shape. Precaution shall be taken to avoid overheating. Heated
steel shall be allowed to cool slowly. External surfaces shall be free
of burrs, sharp edges and corners, except when sharp edges and corners
are required or where they are not detrimental to safety.
Welding. The surfaces of parts to be welded shall
3.11.3
b e free of rust, scale, paint, grease and mill 11 scale that can be removed
by chipping and wire brushing. Welds shall transmit stress without
permanent deformation or failure when the parts connected by the welds
are subjected to proof and service loading. Parent materials, weld
filler metals, and fabrication techniques shall be as required to enable
the loader to conform to the examination and test requirements specified
in section 4. Parts to be joined by fillet welds shall be in close
contact and shall not be separated by more than 3/16-inch unless appropriate
bridging techniques are used. The welding process and the welding
procedure used in fabrication of the loader shall be in accordance with
MILL-W-52574 .
Bolt connections. Bolt holes shall be accurately
3.11.4
formed and shall have burrs removed. Washers or lockwashers shall be
provided where necessary. Matching thread areas securing bolts conforming
to SAE J429 or capscrews shall be of sufficient strength to withstand
the tensile strength of the bolt. All fasteners shall be correctly
torqued and shall-have full thread engagement.
Machine work. Tolerances and gages for metal fits
3.11.5
shall conform to the limits specified herein and on DL 1378AS100, and to
the standards of the Materials Handling Equipment Industry.
