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!
