Here is the Berk opened up.
Note the mounting screw locations |
The loco has a clean look inside. |
The motor has an optical tach controlled feedback for the cruise feature
|
The electronics for the motor driver, sound and smoke are all on this
mother board assembly.
It has a clever plastic shield held on with locking tabs. |
|
|
To remove the smoke unit you must
remove the mounting bracket with these 4 screws. |
Once the bracket is removed you can drop down
the smoke unit to clear the smokestack and remove the unit towards the
rear. |
The smoke unit is the
same design as one used in the AF Y-3. The only difference is the smoke
exit ring on the top of the PC board and the mounting bossed have been
milled off for clearance. Also two mounting bracket holes have been added
to the bottom. |
The motor appears to
be the exact same one used on the Y-3. Part number 610-1154-130. |
I recommend occasional lubrication of the fan motor by
pulling off the impeller and using a drop of sewing machine oil on the
upper shaft bearing. |
The element is also
the same 16 ohm as used in the Y-3 . |
