Product review (5 stars): Works fine!
I actually didn't use all of this part, because I just took the pulley off this one and replaced the old, worn out one on the existing one. It fit perfectly!

I still give it 5 stars because when I compared the old versus the new side by side, the new one looked like it was a suitable replacement. I just felt that the old one was made of hardier materials (it has the gold-tone color of higher-grade steel), and also I didn't want to remove it from the motor bracket and deal with re-stringing the spring and everything.
