Removing the Towfish Electronics

To remove the towfish
electronics:
1. Remove the towfish nose
cone by unscrewing the
socket head cap screw in
the center with an 8-mm
hex key or driver. Once you
have the nose cone off you
will find the push/pull
assembly shown in
Figure 4-8.
This assembly is used to
insert or remove the
electronics from the
pressure housing.
Positioned one way the
assembly screws into the
end cap and extracts the electronics. When flipped over, the assembly pushes
the electronics end cap into the pressure housing.
2. Disconnect all the cables from the bulkhead connectors on the electronics housing
end cap.
3. Position the post with the unthreaded hole to the top.
4. Study the jacking screw.
You will notice the threads
are off center. Locate the
short, unthreaded side.
5. Insert the short end of the
jacking screw, which is
shown in Figure 4-9,
through the post.
6. Thread the jacking screw
into the electronics housing
feed-thru.
7. Place the washer onto the
jacking screw, thread the
nut on and tighten the nut.
This will extract the
electronics housing.
