Need motor suggestion for Rivarossi Con-Cor 2-8-4

[1956Porsche]

I have a Rivarossi Con-Cor 2-8-4 Berkshire that the motor died and looking for a suggested can motor replacement possibility.  Just want to get it running without investing a lot.  The motor measures length 23 mm x width 13 mm x height 16 mm and the shaft is 1.5 mm.   A Mashima #40323 could work, but not really wanting to spend that much money. Again any suggestions?

Thanks,

Joe

I bought one of those brand new way back in the early 90's, and the motor burned up in less than an hour.  Since it otherwise ran nicely, and I was freshly emboldened by having done my first simple remotoring jobs on some N scale engines, I put a Kato diesel motor in it.  As I recall, it was not hard to swap in there.  It was the venerable "GM-5", I think.  But these days, any Atlas or Kato diesel motor ought to fit in there.  They are about that size and have 1.5mm shafts.   I guess I would opt for one of the skew-wound Atlas "scale speed" ones, just because I like the speed range on them.   If I get overcome by ambition, I will get the shell off it to take a photo of the new motor in there.  I have not actually seen it for 30 years, so it would probably appreciate some company.

CORRECTION:  I did open it up.. I put a Sagami 12mm x 20mm can motor in there.  Given its round shape it fit easily into
the space.  An Atlas/Kato motor does look like it would fit, however, and that's probably what I would use today.  Back in the day, Sagami was all the rage.

I used a 14x20 Sagami in this rebuild:  https://www.therailwire.net/forum/index.php?topic=44735.0#msg576380

Why not use a SuperMax motor?    @mmagliaro refurbishes the Rivarossi Can motor with pretty much all the performance you could want.
I have a few of his rebuilt motors and have more to send him.

While this motor would probably work, it is kind of short and fat compared to the available space.  You might not be able to make it fit, width-wise, and it probably does not have a long enough output shaft to mount the worm and reach the worm wheel.

According to Spookshow, there were 3 iteration of that model, using 3 different motors.

One version of that loco used the exact Rivarossi "can"  motor Max upgrades with the new magnet and armature.  That was the mid-life version.

Seems that Joe's us either the initial or the latest version using a flattened shape motor.  But wouldn't that chassis still accept the round (SuperMax) Rivarossi "can" motor?

Yikes.  I stand corrected.  I had no idea they were selling these with the Rivaross can motor in there, but Spookshow's photos don't lie.  The one I bought did indeed have that "improved motor" sticker on the box, but the motor burned out in less than an hour of running anyway.

JOE:
Can you post a photo of your old motor mounted in your Berkshire?  The mounting area by the motor was slightly different for the different motor configurations.  If you look at Spookshow's photos, you can see that the Rowa, and later Rivarossi, had a thinner mounting plate area in front of the motor, whereas the mid-production Rivarossi with the "bad" can motor had a much wider "horseshoe" shaped area in front of the motor.  Either way, looking at his photos, you could indeed use one of my "super" Rivarossi rebuilds, or you could even use one of the base 3-pole skew-wound Mabuchi motors I use for harvesting the new armatures for my rebuilds.  That later Rivarossi motor shown in Spookshow's photos looks just like those.
This guy, here (it's 12v, 1.5mm shaft, and the form factor looks right for a drop-in replacement)
