The first
step I use in dismantling the unit is to
separate the head and primary valve chest
from the secondary valve chest and the
pneumatic boards. This picture
illustrates how the complete unit looks.

This is what
the secondary valve chest and the
punmatic boards look like after the head
and the primary unit has been removed.

Here is the
picture of the head and primary valve
chest. The board that is hanging off the
table is called the "L"
channel. It channels the primary reduced
air signals to the pouches of the
secondary valve unit.

It is now
time to remove the head from the primary
valve chest. The head is the shelf that
sits on top of the primary valve chest
and contains the spool box, transmission,
automatic tracking device and the wind
motor. As you can see in the picture you
must break the lead tubing away from the
junction board before you can remove the
head from the chest. Here you can see
about half of the tubing has been broken
loose.

Notice two
things about the lead tubing. First it is
cloth covered. This is an extra and was
done on your nicer player units to dress
them up. It serves no mechanical purpose
except to give a little protection to the
lead. Second notice the white stuff
inside the tubing. This is lead oxide and
one should be very careful while handling
the this tubing.

With the
tubing broken loose and the screws
removed the head can be lifted away from
the chest and set aside. As you look at
the primary valve chest you will notice
where the tubing was connected at the
rear and you can see the "L"
channel board on the front.

Now the upper
player action is divided into three major
sections. 1. The head, 2. The primary
chest, 3. and the secondary chest and
pneumatic decks. It is now time to
disassemble these 3 individual units.
