Just a quick thread to show a few mods I just did on my Lionel Vision Niagara. While only two items it required a fair amount of disassembly to complete. I wanted to bin the Canon motor and get rid of the bright silver smoke box. I used a 12v 9433 Pittman to replace the Canon and its virtually a drop in replacement. Same bolt pattern and shaft size. Just had to clean up some burrs on the flywheel.

Next repaint the smokebox. I still had some Floquil graphite paint that hadn’t dried up from 30 years ago. Piping was masked off using Micro Mark liquid masker. Its actually a bit darker than what appears in the picture.

I still want to replace the rod screws with something closer to prototype as I did on my TMCC Niagara. Stay tuned.

Just curious, but what was your objection to the Canon motor?

Not to start the debate again:

There are a few people here on the forms that do not like the cannon motors due to them failing and blowing up the command board.

I have been working on a lot of models that have these motors but I have not personally seen any issues. They aren't perfect, but that's the cheapest option available for the manufactures.

Thanks guys. JM I airbrush the smokebox. The top shell was off for the motor swap. I was able to remove some detail. From the bottom shell and pry it up far enough to get paint on it. On the TMCC Niagaras its easier to remove the bottom shell but this engine has many more boards that have to be removed to do that..

Bruk, this what I did on my TMCC Niagara. Flathead allens to sort of give the impression of nuts on the bearing retainers.

D, the Canons have a reputation for failing and shorting out the RCMCs. I have a few Pittmans so its wasn't a huge deal to swap it in.

Also, I don’t care for the overall paint scheme. Not a fan of factory darkened rods. I would rather weather an engine myself. This has the odd combination of as built whitewalls and running board stripe with in service siderods plus the silver smokebox which I have never seen on any Niagara, new or in service. I am leaning towards replacing the running gear with silver and keeping the whitewalls as a fresh from the factory version.

Nice upgrades.

Pat @harmonyards has run that 12V 9433 with success in Legacy Hudsons, so it should work great in your Niagara. I'll be 9433 swapping my own Legacy ATSF 3751 class Northern shortly. I just wish there was room for a 9434 size motor in these Legacy models. Lionel used 9433s in the most of the TMCC versions of Legacy locomotives. Probably something to do with electronics packaging with the Odyssey system.

Lou, the TMCC Niagara has a 9433. No problem pulling 13 18" heavyweights. I debated about using a 9434, its close, but knew the 9433 would work for sure.

Bruk, I have had a number of requests for the rod screws but I don't have a CNC mill. They are pretty tedious to make and yield is nowhere near 100%. Maybe someday I will take the plunge.

Most of the TMCC 4-8-4s used 9433s from what I have seen. I just like the 9434s for the little bit better low speed grunt for starting a train. Seems like once the train is moving there is very little difference between the two.

The painted smoke box looks way better.  Lionel’s choice for bright silver always puzzled me until I found a single photo of a Niagara (I don’t recall which number, I don’t have the book with me) in Know Thy Niagaras with what appears to be a bright silver smoke box.  So there is a prototype for Lionel’s choice, but surely that was an outlier and likely didn’t last long.   Lots of Niagara pictures with stripes and whitewalls.  

Your Niagara looks fantastic with the upgrade.  Thanks for sharing
