Removal
NOTE: Ensure that the chinstrap is
disengaged from the D-rings, and
loosen nape strap pad adjustment.
This will provide easier access to the
helmet for installation.
1. Detach the earcups from earcup
retainer pads by disengaging
hook-and-pile fasteners, and pass
the earcups through the retention
straps. Allow earcups to hang
outside the helmet by
communications cord.
2. Referring to Figure 3-8 , remove the
TPL (or SCL) from the helmet.
3. Referring to Figure 3-9 , remove the
pan-head screw, spring washer,
and post attaching the retention
assembly to the center rear of the
helmet shell. Retain the screw,
washer, and post for reinstallation.
4. Referring to Figure 3-10 , use
a spatula to separate the
hook-and-pile fastener attaching
the energy-absorbing liner to the
helmet shell.
NOTE: Removing the energy-absorbing
liner may require some practice.
5. Carefully slide the energy-
absorbing liner out through the
rear of the helmet, following the
contour of the helmet shell.
