SCANNER REMOVAL, DISASSEMBLY AND REPAIR PROCEDURE
1.Detach motor and scanner assembly (A) from the generator assembly by removing four
(4) nuts from the synchronous motor which anchors the motor to the "L" brackets of
the generator assembly.
2.Remove the cable connections in the organ so motor and scanner assembly is free
from organ.
3. Note A.C., line box, and output connections for reassembly.
4.Locate oil cup (B) and oil felt (C) inside cup. The oil felt must be removed and
the cotton threads unwrapped from the felt before separating the scanner and motor.
Remove felt retainer spring (D) and lift up on the felt to remove the threads. (Do
this very carefully to avoid breaking the cotton threads). After removing the threads
from the oil felt take a pick or a paper clip and remove the three threads from the
one side of the oil cup by pulling them through the hole in the cup. The thread from
the other side of the cup need not be removed.
5.Locate screws (E) which hold the motor and scanner assembly together. Remove the
screws and pull the motor and scanner assembly apart. Note: There is a gear on the
end of the motor shaft and must be guided through the hole of the scanner housing to
separate the motor and scanner.
6.Remove two screws (F) from the rear cover (G) of the scanner. Before removing the
cover note that there is a shielded wire attached to the cover. This wire is
connected inside the scanner and there is very little slack in the wire. Remove the
cover and tip it back carefully so you can see inside. Locate the carbon brush audio
pick-up assembly (J). The carbon brushes must be removed before the main housing
assembly cover (M) is removed, in order to prevent damage to the carbon brushes and
tension springs. Lift end brush (I) and slip the two carbon brushes (H) off the rotor
contact pin. (Be extremely careful of the rotor contact pin during disassembly so
that you do not bend or break the pin).
