That was easy!! Glad I could help!!
Sorry, couldn't resist. Just remember that the only stupid question is the one you don't ask. If only all our problems were that easy to solve.
Cheers!!

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Found it! Screws were under the speakers. Top of chassis lifted off exposing motor and shafts. Noise was a wire caught in a gear tower. It has been a good day.
I am working on a proto 2000 limited edition e8 920 series with the quantum sound dcc board atop the chassis. It grinds topside, a whiny sound in the motor driveshaft area. How do I get to the motor and top gears? Thanks!
