I am upgrading and old T1 6-18009 to ERR TMCC.  All is complete except for the smoke unit. When received, the smoke unit was disconnected. Opening the smoke unit, the gasket was damaged.  Managed to make a gasket, but there was no batting in the unit.

This appears to be a common design for older large engines.  It looks like the air flow path is from the bottom of the chamber, and I'm not sure how to add batting so as to not restrict the air flow.

Any suggestions would be appreciated.

Those units do not get batting.  HOWEVER... Jim Barrett did an amazing article in The Back Shop about making them work better.  It involves drilling a hole through the baffle at the half-way point of the element.  This allows the fluid to travel through the unit even when the liquid is blocking the anemically small area at the bottom of the baffle is submerged.

Thank you all for your comments and recommendations!

While I don't have access to Jim's backstreet article, I understand the need for the drilled hole...   I think I'll also install some batting in the bottom of the chamber.

I guess with this type of smoke unit, if you turn the engine on its side or over it will pee on you!!  ??  Yuk

My customer just wants his smoke unit to work, so will just do what I can to just make it work.

Again, thank you all for your input, much appreciated!

Do you know the issue number?  I have digital access to back issues of the magazine, but there's no search function that I'm aware of.

Does anyone have a pic of where to drill the hole?

I do it right about here. You just remove the resistor out of the way, put on a block of wood, and drill a decent hole. I then countersink the edges of the hole using a larger diameter drill. All you are doing is creating more of a direct airflow to hit the center of the resistor and thus blow the smoke off of it. It also keeps the puddle of liquid from getting blown up and out the stack as larger drops.

How about a much better solution, that won’t break the bank, yet give you smiles for miles,….these smoke units are available from Mike Reagan ( Mikado on the forum ) ……..these units are super easy to install, super easy to wire, and will blow the pants off the old piston type smoke unit. ….on the older Pulmor chassis, you do have to knock off the lever stand offs, but a dremel tool with a cutoff wheel makes even this a trivial chore……

PS, it can be run conventional, or in a command environment…..

How are those compared to the MTH ps1 smoke units? Those are really nice! Lots o smoke. But I'd like to support Mr. Reagan. Maybe send me an email for a link to where to buy when you get a chance. Thanks!

The PS1 smoke unit is user friendly for conventional guys, …for command, the PS1 requires some mods, and fiddling…….Mike’s unit is well rounded, and can be used in either environment. It accepts a chuff signal with a simple tap wire & diode. This makes the unit puff in time with the chuff,…..it also works well in diesel applications,…..Mike is on the forum, his alias is Mikado, search him on the members list, and shoot him an email, …he’ll be glad to expand on what I’ve said……..just like the PS1 unit, the wiring is just as simple, with only one more wire to add,…..footprint is nearly the same!

@Mikado - the smoke unit in the referenced post looks interesting.  Still available?  Details and ordering info?

Thanks in advance.

If you search MTH parts for smoke unit, then filter on "PS 1" (with the quotes), you'll come up with a whole bunch of PS/1 smoke units.  They have different length posts and different stack configurations, pick one that works for you.

This is a good choice, it has separate posts so you can use any length stand-offs with it.
