This one is located in the plastic shell boiler. I am new to AF and don't know the part number. The engine has piston (choo choo) and the nichrome wire runs side to side (not lengthwise). There is also a bottom gasket and cover plate. The bottom gasket and fiber insulator box are rough and should be replaced but I am having a hard time finding those items. Not sure if the top is to have a gasket, or if the top fiber board acts as cover and gasket. Nothing on the bay except rebuilds and/or wrong type of gaskets.
I was able to find wire and wick but also need a brass smokestack. I read where the resistance after the wire is looped around the wick should be about 40 Ohms. The less resistance the hotter (more smoke) but also increases chance for burning the wick. I would like to add a smoke unit on/off switch, but presume this will also add resistance? Are there any good articles on restoring or making such mods to AF smoke units?
Not related to smoke, but is the armature supposed to have a quarter inch (approx) play from forward to reverse? There is only a thin brass spacer on the rear side of the shaft. The brushes are spring loaded and can compensate but the play seems excessive.
Thanks,
Rich
