I took a few pic to share. I only see two screws that look remotely like they might be the ones to remove. They are under a bar that connects to the locomotive wheels on both sides. Those are secured by a flathead screw on each side. I’m guessing I’d have to remove that crossbar to be able to lift the smoke unit out. No other “top” side screws and a can’t see how the front of the unit is held on. The part with the stack.85635B88-94B3-40D5-BDE4-9C280A1F5E319AE56247-4FD3-4BC2-8E58-302004D20F0D0F940507-9875-484B-A1B9-16BEF970CA1ACC3E8489-EB1E-407C-981C-F369E7DF9F04The last photo shows the 2 Philips head screws under the bar holding the wheels. The underside of the carriage is soaked with smoke fluid that I have to wipe off.

 

 Thanks 👍

Yep, the stock wick was just a pad of fiberglass tucked under the smoke resistor, I was pretty surprised when I took one of these apart.  As I upgrade K-Line stuff to command with fan driven smoke, I end up with a number of mechanical smoke units of various sizes.  I have three or four of the horizontal ones like you have, interestingly enough, not all the same exact design.

I’ll take another look inside later. Sometimes I think I’ve gone to the well too many times taking this thing apart. The underside screw holding the smoke unit in has a tiny washer and that was a b*tch to get back in place.

I’ve read someplace that tiki torch wicks have been used for some smoke units. I don’t have the skill set to upgrade to a fan driven unit and I wouldn’t know which one to choo-choo choose anyway😁

Thanks!

No real reason you can't tweak this one.  There is no "direct replacement" for that smoke unit, as you can see it's a unique design.

If I take these out, I put in fan driven smoke.

Would you be able to tell me where I might find a fan driven smoke unit that would fit in this unit or at least a model number?

 Thanks 👍

I put MTH smoke units in them, but you'll have to make a custom mount for it.  It's the MTH AA-0000070 that I typically use, the standard MTH steam PS/2 or PS/3 smoke unit.

For many installations, I have to solder a brass tube to the funnel to mate with the shell stack.  This is an installation in a K-Line scale steam that happens to mate up perfectly without any extension.

The other factor with the MTH smoke unit is you have to change the resistor and also supply a 5V power supply for the fan.  Not a problem with my installs as I am also installing the Super-Chuffer II that provides the 5V fan power.
