PM your email address to me or a cell # and I will send a quick video of spinning my fan by hand for comparison (has around 250k on it, but still fine).
I happen to have a bad one on the 140 next to a good one on the 124. The 124 spins about 90* when I give it a flick of the wrist, the 140 goes a couple of revs.
