Chapter 2: Helmet Preparation and Operation
3. Referring to Figure 2-23 , remove
the two screws, the two washers,
and the backing plate from the
inside of the helmet to detach
the existing bayonet receiver
assembly and the spacer on one
side of the helmet. Discard the
spacer, screws, and washers; you
will replace them with new ones.
4. Repeat Step 3 for the other side of
the helmet.
NOTE: Keep the bayonet
receivers and backing plates for
reinstallation.
NOTE: The kit includes left-hand
and right-hand anti-snag spacers.
Ensure that you are using the
correct spacer for the side of
the helmet on which it is being
installed. Figure 2-24 shows the
right-hand spacer on the right-
hand side of the helmet (as worn).
5. Mark the top spacer hole as
follows:
a. On one side of the helmet,
align the holes of the anti-
snag spacer ( Figure 2-24 )
over the bayonet receiver
mounting holes in the helmet.
(If necessary, adjust the angle
of the spacer to eliminate
interference with the chinstrap
or the grommet.)
b. Mark the helmet through
the top hole in the anti-snag
spacer ( Figure 2-25 ).
c. Repeat Steps a and b to mark
the upper hole in the other
anti-snag spacer on the other
side of the helmet.
