Assembling
1) Clean the slip-ring surface with alchol.
2) Pass the slip-ring assembly through the train shaft and install so that it may be in contact with
the base of the train shaft.
3) Solder leads of the slip-ring and apply silicone rubber over them.
4) Loosen the carbon brush fixing screws and install the carbon brush assembly.
5) Tighten the carbon brush fixing screws so that the brushes contact the center part of the
slip-rings as shown below.
Caution
Do not change the bending angle of the carbon brush.
The angle is set to 30° at the factory.
Figure 5.10
6) Follow steps 1) to 6) of disassembling procedure in reverse order.
Note: The tilt gear should be positioned so that its screw holes may agree with the holes on
the tilt shaft.

5.6 Carbon Brush Replacement
When the carbon brush assembly is replaced, use the procedure for the slip-ring replacement.
When only one or two carbon brushes are replaced, it is unnecessary to disassemble soundome
mechanisms. Unsolder the lead wire and loosen the socket head bolt with the ball wrench
supplied as spare parts.
