Hi Cary,
that sounds not to good...
:-(

I always swapped all 4 rubber bands (at maybe 33% of all my motors - especially
those that have not too much ballast but shall pull longer trains).

Only on 9V nowadays. In the past a few times on 12V as well...

No, I have not, but usually my trains are stored in boxes and they do not run
at all - most of them rest for years (or "forever", since they are not nice
enough for shows and not simple enough for kids). The heaviest engine of mine -
the BR50 stem engine - has a single motor in its lightweighted coal tender.

Therefor I have put bicycle rubbers on that motor and since that moment it runs
fine. It ran for 2 days without breaks at the Legoworld event in Zwolle.
So that is definitely the most used engine of mine and it ran without any
trouble even through curve combinations and points.
The small tan diesel engine (built by Larry P. 3 years ago) is the other "much
used" model of mine.

It is very small, lightweighted and only 4 wheeled - that is the reason, I
always have it with me at any show: it works as test engine as well than as
kids play model (easy to put onto the track). Because of its low weight I added
bicycle wheels on that as well. And it has run for several hours in garden
layouts (my nephew loves that!). And in Zwolle that one ran for lots of hours
as well and pulled 14 smaller waggons without any trouble. So I am really
convinced that these thicker rubber bands are very usefull to strengthen your
motors.

Definitely "NO!"

No, never heard about anything like that....
Good luck for future use of 9V motors! Usually those are very reliable:
Thorsten Wernecke has driven motors for over 4 month nonstop in his wifes
pharmacy window display.
Leg Godt!
