The very first thing to do is draw a circuit diagram of all the tubing (or
plumbing) and also a diagram of all the separate control rods.

You will have to disconnect the control rods that link the main stack to the
front panel controls and also disconnect any controls to the piano action.
Where there is a linkage in a control, label each mating part of the link
with the same letter so that when you come to reassemble, you know that part
A must join up with part A and part B must join up with part B etc.

Do the same labelling procedure with the tubing. You will probably only have
to disconnect 4 or 5 tubes, the main ones being from the main bellows under
the keyboard to the stack and another one usually to the roll motor on top
of the stack. Look for smaller rubber tubing that link the stack with the
controls; sometimes these are hidden under the keys.

Players in the 1920's were designed in a fairly modular way i.e. in
sections. The stack (above the keyboard) usually had the roll motor and
other governing pneumatics all assembled together as one single unit located
by four screws at either end of the stack. The main  pump bellows ,
reservoirs and pumping pedals are usually assembled as a single unit as
well. (Look for wing nuts just under the keybed to release).

Dismantling should take no longer than 45 mins, but reassembling always
takes longer because as Sod's Law states that nothing ever seems to go back
the way it came out!
