R E M A R K S   to the Restoration Procedure:
**************************************************************************
 o  A "Problematic Part" ( see >>> above !) was discovered later:
    The SPRING in this "Locking-Control-Unit" was flipped out and this
    resulted in RANDOM BLOCKING of CRANK and/or CARRIAGE
 
 o  The axle of the INPUT DISPLAY was lubricated (?) with motor oil.
    This tar-like substance was aggressive and expanded the plastic of the
    display wheels: It was a long procedure to separate wheels and
    axle - and all hubs needed special care with a needle file ...
 o  The CRANK BLOCKING had three more reasons:
    (a) COUNTER DELETE was incorrectly assembled
    (b) SPRING in CRANK HANDLE was broken, LOCKING BOLT FORCE too low
    (c) FRICTION in the CARRIER SHIFT LOCK (bottom) was too high ...
 o  RUBBER FEET were decayed; new ones were made out of TUB STOPPERS;
    ( Their LOCKING MECHANISM is now made out of PAPER CLIPS )
 o  Many FIGURES needed restoration with a super-fine black marker ...

(!) REMOVING THE CARRIAGE:
        ( Make sure, that the transport-lock-screw is released !) 
    (a) Reset all registers
    (b) Remove the right lock-block on the bottom of the carrier
        ( remove 2 screws and lift it out of its 3rd anchor )
    (c) Shift the carrier to the left side
        ( push/pull Levers [9]&[5] to pass ...)

(!) Removing the right and left covers of the carriage:
        ( Careful because of falling out springs & Tooth-Wheels !!! )

DETAIL PICTURES for the CORRECT SYNCHRONIZATION ...
LEFT & RIGHT Side of the Carriage  ( Held by a vice !)

  

Observe ORIENTATION of the VISIBLE AXLE-SLOTS !!!
On BOTH AXLES the GEARs with SPRING are equal and to pull/fall(!)-out ...
... FRONT & BACK of the GEARs:  
                                        

The Back-Side-STUD has to fit into a GAP (= opposit of the AXLE-SLOT !)

RE-ASSEMBLING ...     

(a) The LEFT STAR-WHEEL ( see >>>> !) has 2 "Wings" ...
Before sliding in the carriage, make sure, that the "Multiple-Gear-Unit"
has the right position: I marked it with [#] [#] WHITE DOTS on Wall & PIN
(b) Make sure, that the "Bell-Trigger" ( see <<<< !) is pushed in!
