BOV DISASSEMBLY
There are very few parts within the BOV assembly that should be removed
by the user; since many parts (especially the second stage components)
require additional setup by a trained Explorer technician.
• Turning counterclockwise, unscrew the breathing hose ends.
• Remove and inspect the hose end O-rings for damage.
• Using the rubberized end of a pencil or other blunt/soft instrument, insert
the pencil through one of the mushroom valve carriers (moving the mush-
room valve aside first) and gently push out the opposite carrier assembly.
!
NOTE: DO NOT push on the center of the carrier. ONLY push on
the outer edge.
• Remove the mushroom valve carrier O-rings (Fig. 2.13).
• Gently pull out the mushroom valve (Fig. 2.14).
