I can't remember all the posts now but an off balanced blower wheel could have contributed to its failure.
Maybe bad parts? The HVAC people who sold me the motor watched the video I posted and said the cage is probably defective. Would you agree, especially considering my re-adjusting it "solved" the noise issue? They suggested I buy a new cage.

As far as the motor being sized wrong, all that we can basically deduce from that is that the HVAC techs who came out are stupid and/or dishonest, and I am gullible and/or stupid to believe them. Either way, they're coming out again and I'm hoping I don't get screwed over. Any expert advice I can glean from this thread is greatly appreciated.
Thank you for the additional vote of "bad cage".

And now that you have gotten enough "votes" for bad cage you are going to try and replace that yourself too I'm sure.
All jokes aside, you could be a smart guy. You say you know all of these fields of knowledge but you are worried about transformer hum, don't know what causes a wire terminal to burn, didn't know to look at the data plate on the unit THAT SHOWS THE FAN SIZE, but I shouldn't worry that you are competent enough not to get hurt.
The technician diagnosed the problem as the cage being out of balance. He said clean or replace it, so I chose the former. While I had everything out I verified the ceramic piece was not from my heat pack. Put everything back together, turned it on, everything works fine.
A BIG thanks to everyone who helped, and have a happy Christmas! :D
