I gave it 4 stars because the motor does work as in, it turns my dryer drum quietly. I couldn't give 5 stars due to the mounting problems I had to amend.
The mounting pillows fit into the saddles fine, but the problem is on the front of the motor (pulley side). That pillow has an alignment key that fits a slot in the saddle. When the motor was fitted in the saddle correctly the motor frame clears the drum as it rotates. The pillow on this motor was either incorrect or was mounted incorrectly. Once the key was aligned, the frame made contact with the drum rotating. Instead of waiting another 2 weeks for an exchange (with the possibility of the same problem), I chose to use my drimmel to take out the key (it's just plastic molded). This way I could rotate the motor where it wouldn't contact the drum. My only concern is if/when the dryer gets a heavy wet load, the torque required to turn the drum doesn't make the motor twist in the saddle because it has no alignment key now.
If you choose to purchase this motor be sure to compare to your old one. Make sure that the key is facing down and the frame is in the same position.
