Product review (4 stars): Dryer works great again
As others mention - the motor works great and for less than $100 you can pretty much make your dryer new again.  Four stars because it would be nice if it included the motor pulley.  Removing the pulley requires a 3/16 hex wrench; getting the set screw off was the most time-consuming part of my job.  After bending a standard Allen wrench, I headed for Lowes and picked up a 3/16" hex drive that fits in a 3/8" socket drive.  Mounting the dead motor in a vise for stability, I first tried using an impact driver to no avail and then went to the hand wrench and brute forced the set screw loose.  After the screw released with a loud snap everything was pretty easy.  Pulley came right off and went onto the new motor with ease.  As the other reviewer noted you'll have to re-terminate a couple of wires.  Do this before you install the motor as its pretty tight in there.  Secondly, once inside the dryer its almost impossible to see the motor's terminal numbers so getting the connections right can be difficult. I found that writing down the wiring connections and terminal numbers down on a scrap piece of paper before mounting the motor made the task much easier once the motor is mounted.  As always, YouTube for video instructions makes getting the belt back on easier.
