Product review (5 stars): One month later and all is well
I wait a while to write these reviews to insure that the parts work at least for a while.  I installed this kit in my dryer which is a ~30 minute job.  The kit came with good, usable instructions.  This complete rebuild kit is a good idea if your dryer is getting older rather than just the belt (my dryer ~17 years old...had previously replaced just the belt).  The old wheels and clips were looking the worse for being in a hot, dusty environment for so long.  I felt really good about the rebuild.
Top tip:  Plan to spend an extra 10 minutes with your shop vac.  Clean out the dryer cabinet, vacuum around the motor area, and take apart the vent area.  You will be amazed that the dryer can even run with all the dust and lint you find (and vacuum out).
