Product review (1 stars): Idler pulley made of poor quality metal
I needed a new belt & idler pulley for my Kenmore 80 Series dryer.  This product had good reviews, so I took a chance.  The belt was of better quality than I could find at Lowes, and the idler pulley looked like it would work.  I installed both & then ran about 5 loads of laundry through the dryer.  The new belt was definitely louder than my original one, but not too bad.  When I went downstairs to get the final load, I noticed that the drum wasn't spinning.  When I opened the unit, I found that the belt had completely shredded & eventually snapped because the idler pulley had bent up towards the gear on the motor- causing a lot of friction.  I tried to bend the idler pulley back back, and it snapped.  Now, I'm just going to go to Sears to see what they have.  I made sure to keep my original pulley & this one to take there to compare.
