14.1 Purse Line Replacement
The purse line specifications for various models of Bambi
Buckets are given above in Table 2. The tie length refers
to the distance from the fender washer up to the top
side of the lower section of the ring used to secure the
purse lines. The tie length is illustrated in Fig. 35.
The purse lines alternate from one side of the valve to
the other. When threading the valve, insert the first purse
line from one side. The next purse line is inserted from
the opposite side. Any or all lines replaced should follow
the same sequence. Refer to Adjusting Purse Lines in
Dump Valve, Section 11.5. Braided nylon for new purse
lines can usually be purchased locally. Make sure you
use nylon since it is self-lubricating underwater. After
cutting new line, melt the ends to prevent fraying. Using
a lighter tie a knot on the end of a new line large enough
to prevent passage of the line through the fender washer.
A recommended knot is illustrated in Fig. 35.
To replace all the purse lines:
1) Ensure the valve grommets are aligned properly. The
two pairs of grommets with a larger space between them
mark where the valve is folded. When folded correctly
all the grommets will line up. When the valve is correctly
installed in the bucket, the folded seal will be parallel to
the ballast.
2) Ensure the new purse lines are melted at the loose
end, and have a large enough knot to be secure at the
fender washer. See Fig. 35 for recommended knot.
3) Mark the purse lines to the tie length given in Table
2. The tie length is described above and illustrated in
Fig. 35.
4) Thread the purse lines, alternating from one side of
the valve to the other.
5) Starting from one end fold of the valve, tie the purse
line to the metal ring at the mark with a round turn and
three half hitches.
6) Work towards the other end, tying the lines with equal
tension from alternate sides of the ring.
IMPORTANT: The best valve sealing action is
effected when the outside lines of the valve have
slightly greater tension than the inside lines.
Further details on purse line adjustments are given
in Section 11.5.
