Neoprene Neck Dam Replacement:
New Neoprene neck dams are nylon 2 side, 2 color, wetsuit material,
1/8
" thick. Inside is BLUE, outside is BLACK. Both sides are marked at the
front and back center lines to help with alignment for assembly.
1) On a flat level surface, align the proper ends of the split rings P/N
540-105.
Using any type of tape available, duct masking etc., tape both ends together
on the bottom side only, so they will not separate during assembly.
2) MAKING SURE THE BLACK SIDE OF THE
NECK DAM (2) IS FACING OUT, place the dam
on a flat level surface.
3) With the stepped ring P/N
560-078
side having the
most holes, facing up, place the ring, on top of the
neck dam, making sure the center of the ring at each
end and the inside curve of the ring, line up with the
marks on the neck dam. Figs 1 & 2
4) Holding the neck dam onto the stepped ring, lift the 2 parts together and place them on top of
the 2 aligned split rings.
NOTE: The neck dam, stepped ring and split rings MUST be properly aligned in order to get all of
the screws to thread correctly. When placing the neck dam & stepped ring on top of the split rings,
be sure the center (straight) alignment marks on both ends are over the splits in the bottom rings.
