3.6.1 Foreign matter on band seat. Prior to banding, the
band seat shall be free from oil, grease, dirt, rust or other
foreign matter.
3.6.2 Application. The rotating band shall be applied after
final heat treatment of the body, by carefully pressing the band
blank into the band seat so as to make contact with the sidewalls
for a minimum of eight-tenths of the band seat depth. There
shall be no gap between the rotating band and the sidewalls of
the band seat, after the rotating band has been machined to final

the destructive method of testing is used or .009 inches when the
non-destructive method of testing is used.

discontinuities equal to or in excess of the ultrasonic
inspection criteria for the respective zones. The inspection
criteria are notches and holes in a standard (on dwg. 9280420)
which simulate larger metal defects. Ultrasonic inspection is to
be performed in accordance with 9280419 prior to band seat and
thread machining.

preparation are required by component details, the finish
specified shall apply to the indicated surfaces regardless of
contour configuration.
3.9.2 Painting. All paint shall be dry to the touch before
packing for shipment. The paint shall be considered dry when the
soft tacky condition no longer exists and the paint feels firm
when touched with a finger using moderate pressure.

with the assembly or function of the round or which might be
injurious to personnel handling the item.
