I recently bought a used old Shimpo 21 wheel that's working great. I noticed when I turn off the motor it makes a weird sound as it comes to a stop.
Here's a vid of it..
I believe it's in the motor as I don't have the rest of the wheel engaged (Metallic Traction Drive system), but maybe I'm missing something.
Should I worry about trying to fix it? I'd rather catch it sooner if it could get progressively worse.
Thanks for any help with this!
