General Considerations
• Painted and coated surfaces need to be protected from dirt, other foreign matter,
nicks, and scratches.
• Non-painted and coated surfaces must not be touched by the human hand, to pre-
vent corrosive body oils, dirt, and other foreign matter from contaminating the sur-
faces.
• Protect all bearings, bushings, cams, rails, gears, rollers, needle bars, pins, studs,
connecting rods, guide shafts, and other surface finishes from dirt, other foreign
matter, marring, scratches, and nicks, etc.
• Bearing surfaces and shaft bore surfaces need to be thoroughly cleaned and mat-
ing parts oiled before assembly.
Special Packaging
Several parts are packaged in specially sealed packages. These packages keep lubricant on
the parts and protect them from contamination during shipment. To install these parts,
clean your hands and place a small amount of sewing machine oil on your fingers to kept
the integrity of the part intact.
