I agree with Pat about mounting in the shell. I’ve just gotten use to making a mount to the frame. Anyway, although I’ve used the GRJ chuffer after converting to can motor I think this would work for the original Lionel pulmor motor as well. I had a small flywheel made only to mount the tape. I mounted it to the worm shaft before the coupling.  Could work for either smoke unit.

There might be a problem with this. I am not that familiar with early TMCC but don't think there is a place on the LCRU to connect a chuff switch to, mechanical or from GRJ's Super Chuffer. The engine now has a reed switch in the tender truck plus an IR tether. If you put a switch in the engine you would have to add a pair of wires from the engine chuff generator to the Railsounds board.

Other options would include replacing the LCRU with an ERR AC Commander which does have terminals to accept a chuff switch as well as being able to drive RS2.5 through the IR tether.

Lastly as the drivers on this engine are screwed on, you could use an optical detector on a driver that would detect lines as a chuff switch. Unfortunately no canned option available yet and though the circuit is simple it still requires skills in fabricating circuits.
