Removing the TRAMECHA Assembly
Remove the CL. base assembly and tray.
Reference: The TRAMECHA assembly can be
removed without removal of the
mechanism board.
1. If the TRAMECHA assembly is lowered and it is
located out of the PLAY position, turn the idle gear
in the arrow-marked direction so that the hole in the
part f of the tray gear meets the hole on the CL.
base assembly. (Set the TRAMECHA assembly at
the PLAY position.)
2. Remove the three screws B fastening the
TRAMECHA assembly and then remove the
TRAMECHA assembly upwards from the front side.
3. At the same time, remove the spring from the groove of
the CH. base assembly in the part g of the TRAMECHA
assembly.
Note: When reinstalling the TRAMECHA assembly:
Check to see if the spring is properly
engaged with groove of the CH. base
assembly in the part g of the TRAMECHA
assembly.
After making sure that the three insulators of
the TRAMECHA assembly are properly set
on the bosses of the L. base assembly's
guide, fasten them with the screws.
