Product review (4 stars): Double check your models' numbers
Our dryer went and, after much research, discovered we needed a new motor.  After having great luck with Amazon and finding awesome deals, I figured I'd order it here.  When it arrived, one major telltale sign (that it wasn't the right one) didn't stick out right away so, in my excitement of having a working dryer, I ran downstairs to put it in.  It didn't set right so it made it really hard to get the spring clamps back on.  Then once I got it all back together and turned it on, there was an awful scraping sound.  Upon investigation, the blower fan was now rubbing on the housing of the dryer vent.  Ripped it apart again and compared it to the bad motor.  Stood them on their ends and the new motor was a half-inch shorter pulley end to blower fan end of the shaft.  On a repair forum, someone suggested maybe it was another motor and posted a pic and that's when everything clicked.

On the blower fan end of the motor shaft, the collar around the bearings is BLUE.  The new one I received was ORANGE.  That was the major difference!!  And, nowhere on the new motor, did it say the model number 279787.  The model I needed was 279827 as shown in the above pic. So, now being shafted out a return shipping fee of $10.50 (but was promised a 20% discount on my next order...yeah like I'm going to chance dealing with THEM AGAIN!!), I wanted to make sure everyone knows what they're truly looking for.

This motor is for pre-1996 dryers so that gets you a head start.

279827...Can also be referenced as 3395652 (old Whirlpool motor order number), 695925, 8066207

279787...Can also be references as 8539556, 3395654, model S58NXMZS-6968

There's many other parts numbers that can be cross-referenced with the 279827, but the big difference is the color of the bearing collar.

As far as the motor itself is concerned...it's a good motor.  Like others have posted, it's not as quiet as the original, but not much louder and hey, if it works, who cares?!?  :-)
